Description

Novel matts and using method thereof

Technical field: the novel matts of the present invention relates to a kind of grid and the using method thereof of practising Chinese characters, especially relates to a kind of grid and using method thereof of exercising Chinese characters.

Background technology: the matts used now, roughly coordinates because of it and adapts to stroke and design feature in block character word, in addition brief, directly perceived, convenient, and is commonly recognized, and becomes exercising Chinese characters always and uses grid the most general at most.But matts exists obviously not enough, epi region 7 is not had to indicate, especially the periphery of word is not provided and close on reference to and/or limit control dotted line, the lump-sum stroke that relates to word periphery or stroke end points is caused not to have basis on location, when writing stroke from the center of word far away with close to follow one's bent, extremely inconveniently determine position, cause following consequence:

1. cannot unify to fix multiple word font size, let alone whole page entire chapter word font size is consistent;

2. there is no division and the sign of epi region 7 and main body matts 2, word periphery is not had to paste word or nearly word reference dotted line, when easily making to practise handwriting, the extension stroke of word and main body are not distinguished, thus can not pull open the two and should have distance, cause writing overcautious and run counter to the radial feature irregular and tight inside but loose outside that Chinese character should possess;

3. the situation that peripheral stroke is straight and oblique and degree, its bending situation and degree, be not easy to hold because far away with reference to dotted line, greatly reduce and write accuracy and standardization;

4. must now write outer blank of now writeeing down characters, add and be hard on and workload;

5. what word peripheral reference dotted line and epi region 7 indicated lacks, and having made receipts pen and row pen decide time lengthening when locating, having greatly reduced writing speed;

6. do not have for the lattice in the elementary stage of practising handwriting of comprehensive or multi-faceted reference, with one to end, to be unfavorable for practising handwriting by easy stages, to reduce the quality and speed of practising handwriting and consolidate word.

China Patent Publication No. 201210188058.4, publication date on October 24th, 2012, the name of innovation and creation is called " in one, lattice and Writing method thereof are write in word location in heart ", and this application case has done a part of repairing to above-mentioned defect, but still there is more shortcoming.

1. well-known, Hanzi features and shape attractive in appearance are that slightly long in regular script side, the flat side of lishu, seal character is rectangular." the interior matts " of foregoing invention design is suitable for this feature, but the outer grid with its collocation is all designed to square.For inner-outer sleeve lattice, people generally feel is, inside and outside should with same shape, collocation just shows nature, harmony, comfortable in the same way, conform with visual custom, and the relevant design of these innovation and creation has run counter to this rule, therefore obviously not enough in harmonious aesthetic;

2. do not indicate epi region 7, to write different model word, to the main body of word and epitaxial part write with reference to, strengthen normalized written and raising speed is still unfavorable further;

3. matts inner cross line simple, does not need to streamline any further into central point.Because matts is used for greatly practicing write hard-tipped pen small character, uses containing cross curve matts, practised by stage, after level and ability improve, the center of less square region is easily seen and knows and perception; If middle word or large word lattice, cross curve and even rice wordline must be used again.Therefore, use central point impracticable, and unsightly;

The patent application document that the present inventor submitted on 01 28th, 2014 to Patent Office of the People's Republic of China, the name of innovation and creation is called " novel matts and using method thereof ", this application case compensate for above-mentioned shortcoming, but still has excellent novel matts can repair above-mentioned deficiency.

Summary of the invention: object of the present invention to be provided convenience further practical novel matts for above-mentioned shortcoming.

The present invention is achieved in that

Comprise being rectangle or foursquarely writing matts square frame 1 of dotted line, write in matts square frame 1 and be provided with being rectangle or foursquare main body matts 2 of dotted line, main body matts square frame horizontal line 3 is parallel with writing matts square frame 1 horizontal line, main body matts square frame vertical line 4 is parallel with writing matts square frame 1 vertical line, and the same central point writing matts square frame 1 of main body matts 2 is same point; Described main body matts 2, be dotted line be rectangle or in square main body matts square frame, be provided with the orthogonal central horizontal line main part 5 of dotted line and central vertical line main part 6, central authorities' horizontal line main part 5 is parallel and join with main body matts square frame vertical line 4 with main body matts square frame horizontal line 3, central authorities' vertical line main part 6 is parallel and join with main body matts square frame horizontal line 3 with main body matts square frame vertical line 4, and the intersection point of central horizontal line main part 5 and central vertical line main part 6 is same point with the central point of main body matts square frame; Describedly writing matts square frame 1 and dotted line master by dotted line and stop the novel matts that matts 2 forms, is on 01 28th, 2014, the present inventor apply for a patent sisters' lattice of novel matts one to ten three, be called novel matts 14.

In above-mentioned grid, write the part in matts square frame 1, belong to region of writing; The main part of extension word, main body character and half are received word and are all write within this main body matts 2; Writing matts square frame 1 is the position highlighting the arrival of stroke outer end or close on; The part of writing between matts square frame 1 and main body matts square frame belongs to epi region 7, is the region at the epitaxial part place of extension word.

The novel matts 14 of the present invention, during because writing, part highlights the outer end points of stroke and need arrive and write matts square frame 1, does not namely stay beyond region of writing blank in lattice.So, when printing use, lattice and compartment should be left space.With the external space, this space takes notice of that justice is upper identical with containing the region of writing in solid line foreign side sound of laughing son, but novel matts 14 does not have unnecessary central object-line than existing matts, " body " (lattice) are placed in advance outward by without the blank of writing value, replace with the form blanked in advance and now write the mode now blanked, greatly reduce the loaded down with trivial details and misalignment degree of writing! And in " body ", make the main body matts 2 having much and write with reference to being worth, namely mark off epi region 7 and main body matts 2, for show various stroke folding and unfolding difference, determine variety classes Chinese character size and avoid overcautious etc., provide a great convenience! More than design significantly improves the practicality of lattice of practising handwriting!

The using method of novel matts 14: coordinate the novel matts one to ten three of its sisters' lattice, according to hobby, is accustomed to and needs, and to 14 kinds of grid, preferably uses.Adopt follow the prescribed order, incremental, progressively improve use lattice calligraphy practice method, for the person of the practising handwriting grasp of characteristic of Chinese character being used to degree and writing ability difference, concrete use step is:

(1) one is selected to practise handwriting novel matts two to five;

(2) practise the some time, understood calligraphy knowledge such as highlighting the adduction such as stroke and interception stroke, Chinese character main body and extension, after the cognition of stroke and structure and writing ability are improved, in novel matts seven to ten four, select a kind of use;

(3) continue exercise a period of time, after adaptation, perception and writing ability improve further, select novel matts six;

(4) practise a period of time further, after using degree and writing ability comparatively strong to the grasp of characteristic of Chinese character, the dependence of grid is obviously reduced further, then selects the exercise of novel matts one;

Use for the grasp of characteristic of Chinese character the person of practising handwriting that degree is stronger, the following step preferably uses lattice calligraphy practice method:

(1) in novel matts seven to ten four, one is selected to practise handwriting;

(2) practise the some time, use the exercise of novel matts six;

(3), after continuing exercise a period of time, to little type-word, tackle stroke, highlight after the aspect knowledge of Chinese characters such as stroke improve further, select novel matts one to do to consolidate exercise.

Without the need to superfluous words, allly to practise handwriting period, must in conjunction with studying hard calligraphy knowledge, learn and complement each other with practicing.By conscientiously exercise and the raising in above-mentioned several stage, inevitable repeatedly generation of writing level runs up to qualitative leap by what measure, until after expertly can writing out specification and even beautiful Chinese character, just can depart from lattice writing Chinese characters of practising handwriting.

In summary: the novel matts of the present invention 14 compares existing matts, has the following advantages:

1. font size: be easy to determine font size, makes similar word in the same size;

2. exact specification: greatly can reduce the misalignment degree that stroke and word portion are arranged, improve the standardization of Chinese-character writing;

3. folding and unfolding has certificate: the setting of writing matts square frame 1 and main body matts square frame, be convenient to word periphery and main body character or main part and write reference, the epitaxial part of word is played and guides and/or the double action of limit control, the main part of main body character or word is served to sign or the suggesting effect of homepitaxy maintenance short distance.Both easily started to write and write, located large, medium and small word, can make again write and avoid overcautious shortcoming, strengthen the subjective initiative to putting outside stroke adduction, thus make write and more meet Chinese character important feature tight inside but loose outside;

4. keep away tired just letter: objectively naturally to be blanked in advance loaded down with trivial details showing that writing now blanks and replace with misalignment, avoid and to be hard on and unnecessary thinking is weighed, thus greatly reduce workload; Eliminating writing adiaphorous ruling, solving and highlighting stroke outer end all the time and can not push up and to reach or near the prejudice of grid outer edge, and using grid outer edge also as a difficult problem for nearest line of reference;

5. speed-raising and strong god: because of inside and outside abundant with reference to dotted line, rises and receives pen and the particular location of wieling the pen easily is selected, therefore substantially increase writing speed and efficiency, and therefore strengthens shape between stroke and connect and connect effect with god, enhances flavor expression;

6. correct simple and easy: inside and outsidely weigh contrast with reference to dotted line because be easy to contrast, thus substantially increase that teacher comment or autoscopy correct quality and speed;

7. be beneficial to laddering practising handwriting: coordinate the use of novel matts one to ten three, be beneficial to and follow the prescribed order, practise handwriting by easy stages, improve the quality and speed of practising handwriting and the effect consolidating word.Completely eliminate on difference writes basis and Different age group still uses the defect of the grid of incompatible with it, unfavorable raising writing skill, solve do not distinguish, end, inconvenience improve with one problem.

In addition, retain or/and improve all advantages of matts:

1. four regions: it is equal to write four regions in matts, for the well-balanced arrangement of block character four parts provides great convenience;

2. center of gravity arrangement: be convenient to the multi-faceted reference of stroke inside and outside word, thus make the arrangement of Chinese character center of gravity more convenient;

3. ruling is suitable for: all using transverse and longitudinal line as ruling, meets human vision custom, be convenient to again by all for Chinese character straight, tiltedly, the position of curving, flat stroke and direction ruling do reference and comparison and write;

4. word lattice are harmonious: block character (containing word state) is outwards divided into four parts from word center by central horizontal line and central vertical line, word dative cooperatively interacts, and it is all symmetrical regular, feel pleasing to the eye, happy, natural, do not have that existing a lot of lattice have make us gloomy, awkward, confusing inclined side line, strange shape line, confused line intert, and makes word dative the relation harmonious;

5. practical and attractive: lattice design is brief, intuitive and convenient, not only practicality but also attractive in appearance.

In addition, comparatively " in one, matts is write in word location in heart ", the present invention has following beneficial effect:

1. more harmonious: to add the outer grid of rectangle, territory, block, field in configurable rectangle or square, thus outer grid 1 can be reached, consistent, the object of getting along amiably and peacefully of shape between territory, block, interior field and Chinese character three;

2. do not abandon leading: the use of central horizontal line and central vertical line is carried throughout, internal field territory, block make brief, attractive in appearance, naturally indicate, both avoided in matts the multiple drawback of practising handwriting not dividing and bring, turn avoid " in one heart word location write matts " with put replaced divide equally and mark to etc. the Central Line of Main Function and the practicality of mistake that causes and phenomenon attractive in appearance;

3. be convenient to stroke location (also for matts is not available): partial grid clearly marks off epi region 7 and main body matts 2, be convenient to Chinese character main part and/or epitaxial part to check the number respectively in main body matts 2 and/or epi region 7, be more conducive to strengthen the convenience and standardization write;

Therefore, novel matts 14 is than existing matts and " in one, matts is write in word location in heart ", and tool has an enormous advantage.Greatly must improve specification aesthetic measure and writing speed that handwriting practicing person writes, make to practise handwriting good and fast." draw bow strong when drawing ", " a workman must first sharpen his tools if he is to do his work well "! Adopt superior lattice of practising handwriting to practise handwriting, the good result of getting twice the result with half the effort must be played!

Accompanying drawing illustrates:

Accompanying drawing is that the novel matts of the present invention 14 is applicable to exercise regular script schematic diagram and schematic diagram (belonging to preferred grid pattern) write in regular script.

In figure: write matts square frame 1; Main body matts 2; Main body matts square frame horizontal line 3; Main body matts square frame vertical line 4; Central authorities' horizontal line main part 5; Central authorities' vertical line main part 6.

Embodiment:

1. the decision design of novel matts 14 and use (setting forth for regular script lattice used):

Observe with study at all times famous expert's standard Chinese character and daily finding Chinese character known, regular script the most attractive in appearance and running hand font are that Fang Erwei is long.Therefore, if the shape of writing matts is consistent with above-mentioned font, is just more conducive to reference nearby and seems that word lattice are harmonious.With the height writing matts square frame 1 and wide ratio within the scope of 10:8.8-10:9.6 for good, preferred proportion is 10:9.

Cause " painting and calligraphy are avoided full ", palpus spacing between word and word, " meter is worked as black in vain ", so class lattice should not lattice dative leaning on, must deposit at regular intervals, its interval is identical with the meaning that must blank in solid line lattice, but such lattice have concisely pure, there is not the clear superiority of unnecessary line.Lattice dative spacing distance can calculate according to directly removing on the basis of existing matts the outer novel matts mode of the present invention that grid retains of solid line and use, and also can slightly increase and decrease.Optimal way is: according to write across the page or perpendicular aspect needs and order the is horizontal lattice dative spacing such as to write and vertical lattice dative spacing different; In addition, according to presentation direction, coloured dotted line or colourless indentation line (being preferred with solid line) can be adopted a side of unit lattice or dual-side to be coupled together; Also can dotted line or colourless indentation line be set between the cell of row or column, to strengthen the connecting of row and row, column and row; Certainly, equally can with pinyin lattice, rectangular space or rectangular lattice with the use of.

3) epi region 7 and main body matts 2 decision design:

(1) mode: the long limit that matts square frame 1 is write in order is parallel with the long limit of main body matts 2, even both directions are identical.

(2) scope is set: can using the height of " state " word and width as main body matts 2 the roughly standard of height and width, make the wide or high sum of two epi region 7 in the same way account for and write the wide or high 25-50% of matts.

2. dotted line: novel matts 14 dotted line used, with short-term or some composition, is preferred with short-term; Described point is polygon form point or round dot, is preferred with square points.

5. according to characteristic of Chinese character science lattice: existing for regular script, tell about the using method of novel matts, lishu and writing of seal character can with reference to regular script lattice methods.In addition, regular script lattice used are also suitable for running hand exercise lattice, difference is, practice and write running hand and notably make word periphery highlight a face more stretching and make widely known, in one page, the stroke that highlights of minute quantity word is better with offscale (go out and write matts) in various degree, and among a word, offscale stroke is generally one or two (length that acts improperly when being two difference).

1) stroke and interception stroke is highlighted:

(1) periphery highlights stroke:

Irregular is the important feature of Chinese character, the side of good multiword or every side of two, three, four sides, outside having a unicursal " punching " drawing to its more highlightedly towards a direction, end points extension, even obviously extension, protrudes from other stroke, this kind of stroke just belongs to periphery and highlights stroke, referred to as highlighting stroke.Have a small part word the same side to contain two and highlight stroke, the individual malapropism of left, center, right structure also has the same side and contains the situation that three and even four highlight stroke, and when just the same side highlights stroke more than containing two or three, each stroke highlights degree slightly difference.Highlight stroke comprise horizontal, vertical, skim, right-falling stroke and hook segment picture etc.Such as: the short perpendicular and long horizontal stroke of " going ", the Nun of " greatly ".In following rich exhibition word, the end points that most numeral highlights stroke can reach word wide limits.

In novel matts 14, usually order highlights stroke and to reach or close to writing matts square frame 1.

(2) peripheral interception stroke:

The periphery of word horizontal, vertical, flatly to skim, to roll over, to carry, point (part), hook (part) etc. draw now, other stroke is to this picture or leave or lean, and do not intert and belong to peripheral interception stroke through, this type of stroke, referred to as interception stroke.As the slash of " doing ", " as " right side cross break, the horizontal stroke in the perpendicular slash of " skin " and horizontal hook and hook, the peripheral stroke of " state ".Interception stroke is divided into local interception and the interception of full side.Local interception stroke is that in word, the part of unicursal to the side of word plays interception function, as " to " in first horizontal with carry; Whole interception is that unicursal is all tackled word side.As the lifting-hook of " arriving ".

In novel matts 14, order peripheral interception stroke is within main body matts 2 or near main body matts 2 sideline usually.

2) font size and use lattice:

Adopting Chinese character form size has difference because stroke length is different with stroke combination situation.With regard to Chinese character size, weigh with left and right width or upper-lower height, be divided into extension word, main body character and half receives word three class, also can be called large size word, medium size word and small size word, wherein extension word comprises epitaxial part and main part, and main body character and half is received word and only had main part.This kind of dividing mode be so that distinguish and write different model and shape word for the purpose of and principle.

(1) extension word and epitaxial part thereof:

A extension word word wide (height) limit: in principle, wide (height) with the word of the widest in section word (height) spends, for writing matts wide (height) degree in novel matts.The outside of block character is divided into four sides up and down, every one or strokes stroke are towards direction, left and right two or a direction or obviously stretch towards upper and lower two directions or a direction or put, reach or close to word that is wide with word in a section or word high limit be extension word, also abduction word or rich exhibition word, large size word can be called, as: " company ", " one ", " blowing ", " the present ".Can push up and reach word stroke that is wide or word high limit and be generally and highlight stroke.

With regard to extension direction, extension word is divided into horizontal extension word and vertical extension word; With regard to extension degree, extension word is divided into limit extension word and slight extension word, it is limit extension word that the one or both sides of word, three sides, four side stroke end points reach word word that is wide or word high limit, as " spring ", " my god ", in novel matts, for limit extension word, its limit extension stroke end points should be leaned and write matts square frame 1; And slight extension stroke (interception stroke or highlight stroke) end points is placed in from writing matts sideline or there is a little distance on border, about the centre position of epi region 7, as: " rich ", " bucket ", " specially " three word, the limit extension strokes such as vertical stroke need be leaned when writing and write matts square frame 1, and the end points of the long horizontal stroke as slight extension stroke is written to the centre position of epi region 7; Stroke or stroke end points in direction, left and right two all slight adduction or in Xia Liang direction, upper left all slight adduction and have the word of a little distance to belong to slight extension word from word wide limits, as: " toot ", in writing, or stroke end points should be highlighted be placed in the interception stroke of word both sides and have a little distance, about the centre position of epi region 7 from writing matts square frame 1.In Chinese character, major part belongs to extension word.

The main body of b word and epitaxial part:

For extension word, if remove limit extension word periphery to highlight highlighting part, slight extension word interception stroke or highlighting a little of stroke of stroke, the width of the part of institute's surplus is equivalent to the width of following main body character, then this part belongs to main part, above-mentioned removed part belongs to the epitaxial part of word, top as " China " belongs to main part, and the both ends wider than main body in long horizontal stroke belong to epitaxial part; Main body character and half is received word and is only had main part, and half receipts word is narrower than main body character.

(2) main body character:

The word that every one or strokes stroke are greater than again word wide limits or word high limit one half-distance relative to word wide limits or the obvious adduction of word high limit is main body character, also can be called adduction word or medium size word, as: " state ", " field ", " even ".With regard to adduction direction, main body character is divided into horizontal main body character and vertical main body character, and the wide word equaling main body character width of word belongs to horizontal main body character, as: " state ", " power ", " even " " district " " cutter "; The high word in main body character height of word belongs to vertical main body character, as: " day " " mountain " " six " " ugly " " king "; Double corpus word is as little in Chinese character in the word such as " field ", " returning ", " day ".

In writing, the main part of main body character or word is usually made to be in main body matts 2.A lot of interception stroke becomes the outer end stroke of main body character, and such as: the lower right side folding picture of " easily ", left side vertical stroke, right side folding picture that " making a noise " " holds high ", the bottom side folding picture of " change ", is main body character periphery interception stroke.

(3) partly word is received: have the width of a small amount of word word or highly account for the half of limit extension word, this kind of word belongs to half receipts word, as: " moon ", " mouth " " fore-telling ".When writing, generally half receipts word left and right sides end points is written on and writes the centre position of matts vertical edge line to central vertical line.

The peripheral stroke of matts square frame 1 pair of word of writing in novel matts 14 serves closely marked effect; And serve outside guiding function to highlighting stroke, guide it to arrive at and write matts sideline.Especially left and right sides is highlighted to the guiding of stroke, serve significant anti-overcautious effect; Wherein main body matts 2 is the location of main body character and extension word main part, provides conveniently; Novel matts remains the cross curve of matts, only accounts for write matts width or height 1/2 and occupy write the determination that half of matts middle position receives word stroke to distribution range, very favourable.Meanwhile, paste word or nearly word write matts square frame 1 pair of font and stroke serves limit control effect, make the well-balanced harmony of each font size.

To sum up, novel matts be the main body of extension word and epitaxial part, main body character, half receive word location, for showing its folding and unfolding difference, provide a great convenience, especially fully can show that highlighting a face stretches the characteristic made widely known, meet the important feature that Chinese character is tight inside but loose outside, free and easy overcautious, not stiff, and there is not the mixed and disorderly property increasing line index, make grid not only practicality but also attractive in appearance, changing in matts all the time the folding and unfolding of above-mentioned word or stroke without with reference to without guiding unlimited control, causing not simple and easy inconsistent nonstandard drawback of writing!

Indicate, guide, limit control be novel matts to the peripheral stroke specification writing of Chinese character, unified font and avoid overcautious, show graceful major contribution!

3) correspondence is divided equally: in matts, have two central authorities' lines anyhow.Moment before writing, the height of word and width are corresponded to write in matts in the heart.So, each several part component of word is suitable, just well-balanced harmony of writing.

Part word, does not belong to the word that four sides is substantially well-balanced.Note having write stroke angle and length according to ruling, just can make barycentre steadiness, natural beauty.

4) stroke reference: stroke angle is the principal element of stroke.The accurate location of novel matts to stroke angle provides brief and sufficient line of reference and/or reference point.Novel matts is inner and peripherally all possesses with reference to dotted line, for the length of each position stroke in word, angle, curvature are determined all to provide with stroke midway metamorphosis sufficient with reference to dotted line, chooses nearby that line of reference or reference point be as a reference when writing.For the inside stroke of word, with reference to central horizontal line and central vertical line, for the peripheral stroke of word, with reference to writing border that matts sideline or border or end points indicate, comparing property is write respectively.

5) center of gravity of word and novel matts: novel matts is inside and outside sufficient with reference to dotted line, plays a good role to steady Chinese character center of gravity.

(1) want apparent place to choose line of reference and write vertically or near vertical nearby for the vertical stroke in word, part folding picture.

(2) by perpendicular in word, longly skimming, the chief editor such as long right-falling stroke, tiltedly hook reserves relative to vertical line in contiguous lattice that gradient is coherent writes, note writing foot length degree simultaneously.

(3) left and right for correspondence is drawn, and namely long slash and length are erected, as " use "; Perpendicular and perpendicular, as " state ", " mountain "; Oblique slash with tiltedly press down, as " order ", " people "; Oblique slash and long point, as " no ", " little ", except long skim with long perpendicular except, it is suitable to draw angle of inclination about noting making it when writing.To this kind of stroke, consider angle with reference to the longitudinal dotted line closed on or oblique line and write.

(4) for single character, containing up-down structure word or parts, surround structure, note when writing making the line of the mid point of relevant stroke and the central point of top and the bottom be parallel to vertical line in contiguous lattice, field wordline end points composition vertical line or write matts border, as " many ", " pungent ", " portion ", " degree ".
