Description
Technical field
The present invention relates to field of measuring technique, are more particularly to a kind of drainage rapid and accurate determination smallclothes irregularly shaped object
The method of volume.It is particularly suitable for the irregular living materials body such as plant leaf blade, fruit in the Ecology investigation of field
Product Fast And Accurate Determination.
Background technology
Volume is an important feature amount of object, has there is various assay methods, is also had to regular object each
Kind calculation formula can use.But the quick measurement of the volume of irregularly shaped object is still comparatively laborious, is measured using drainage
The volume of irregularly shaped object is simplest method, is generally measured to larger object.Modern computer three-dimensional reconstruction
Development also provide mature technology for irregularly shaped object cubing, but the required equipment limit technology is in a large amount of fields
Use in work.More particularly, in the investigation work of field Ecology, a large amount of days irregular, quality is different
The quick measurement of right object is almost not achievable task, therefore object volume is hardly the measurement in these investigation works
Index.
At present in Ecology field investigation work, to the irregularly shaped object such as blade, fruit being related to, one
As only measure length (or thickness), weight etc. and have the index of canonical measure apparatus.Volume is not measured generally.One
The reason is that these living materials often come in every shape, conventional measurement means can not be used to measure, on the other hand also in that these
Material is often lighter than water, it is difficult to is convenient for measuring with drainage.
Invention content
In order to solve the problems, such as above-mentioned irregularly shaped object cubing, the purpose of the invention is to provide one
Kind using drainage rapid and accurate determination irregularly shaped object volume method, this method is easy to operate quickly, and accuracy is high, can be with
Easily used in biology, ecological environmental condition in the wild.
In order to achieve the above purpose, the present invention uses following technical measures：
A kind of method of rapid and accurate determination irregularly shaped object volume, includes the following steps：
1, the syringe (common) for selecting certain specification, including syringe needle.
In actual survey work, the syringe of 50ml specifications disclosure satisfy that mostly with the cooperation of 1ml 2ml pipettes
Needs in the case of number.
2, injected clear water (tap water) in syringe excludes air by following method and vertically upward by syringe needle uses finger
It flicks syringe while slowly pushing piston, air is discharged by syringe needle, ensure that clear water is accurately full of the maximum of syringe and carves
At degree.By taking 50ml gauge hypodermic devices as an example, it is accurately full of 50ml clear water.
3, syringe piston is slowly exited, with rubber cap closed injection device front end before extracting out, prevents clear water water clock.
4, syringe piston is removed, object under test is put into syringe cylinder.
5, syringe piston is closed, changes syringe top rubber cap into syringe needle.Syringe needle is upward, by abovementioned steps (2) side
Air is tentatively discharged in method；
6, according to scale where piston at this time, the pipette (common) of dimension is chosen：It is applicable in 50ml syringes and is
Example selects 1ml glass pipets, if being above standard 50ml if scale where piston, which is more than 50ml master scale lines, is less than 1ml
Graduation mark selects 2ml glass pipets within the scope of 1-2ml.By pipette tip rubber cap closure, syringe needle
Head is pierced into pipette tip rubber cap and enters in pipette.
7, syringe and liquid relief tube complex is upright, piston is pushed, is remained in step (2) Inside Syringe according to a conventional method
Remaining air and liquid, until piston arrives at label where specification of syringe.By taking 50ml syringes as an example, piston is pushed into 50ml marks
At note.
8, in pipette the volume of clear water be object being measured volume.Use the stereometry essence of 1ml standard pipettes
Degree can reach 0.01cm3。
It is of the invention it is critical that the ingenious beam that syringe measuring targets are utilized by above-mentioned technical measures
It ties up, no matter whether object under test can swim in the water surface, using drainage Accurate Determining volume.Utilize standard size wooden unit
(1×1×1cm；0.5 × 0.5 × 0.5cm), glass marbles (diameter 1cm) examine, gained measure volume with calculating volume it is consistent.
For exobiology out of office with Ecological Investigation, the present invention is nondestructively measuring to the measurement of biological living volume,
Detected materials can also be used to measure other indexs.Such as blade, after having measured volume, it may also be used for length, width,
The measurement of the indexs such as thickness, chlorophyll content, realization measure each measurement index in same measurement object.
Compared with prior art, the present invention haing the following advantages and effect：
1, this method is simple and convenient, and article used is the product for having various unified standard specifications, can spirit as needed
It is living to select.
2, this method measurement result accuracy is high, and precision depends on the precision of pipette.
3, to object quality to be measured without selectivity, no matter rising and falling can measure this method.
4, this method determination efficiency is high, and a large amount of volumetric quantities can be quickly obtained without special training.
Specific implementation mode
Embodiment 1：
A kind of method of rapid and accurate determination irregularly shaped object volume, step are：
1, the syringe (simple glass syringe) for selecting certain specification, including syringe needle.In actual survey work, 50ml
The syringe of specification disclosure satisfy that needs in most cases with the cooperation of 1ml or 2ml pipettes.
2, injected clear water (tap water) in syringe, routinely application method exclude air：Syringe needle is upward, use finger
Syringe is flicked, while slowly pushing piston, air is discharged, ensures that clear water is accurately full of at the maximum scale of syringe.With
For 50ml gauge hypodermic devices, it is accurately full of 50ml clear water.
3, syringe piston is slowly exited, with rubber cap closed injection device front end before extracting out, prevents clear water water clock.
4, syringe piston is removed, object under test is put into syringe cylinder, closes piston, changes rubber cap into syringe needle,
Air is tentatively discharged by aforementioned method steps (2).
5, the amount for exceeding master scale line according to top land, selects the pipette of certain specification：It is suitable with 50ml syringes
For, if scale where piston, which is more than 50ml master scale lines, is less than 1ml, that is, 1ml glass pipets are selected, if being above standard
50ml graduation marks select 2ml glass pipets within the scope of 1-2ml.Top rubber cap closure, syringe needle is pierced
Enter pipette tip rubber cap to enter in pipette.
6, syringe and liquid relief tube complex is upright, piston is continued to press on, according to a conventional method step (2) Inside Syringe
Interior air and liquid, until piston arrives at label where specification of syringe.By taking 50ml syringes as an example, piston is pushed into 50ml marks
At note.
7, in pipette the volume of clear water be object being measured volume.
The measurement accuracy of this method measuring targets volume is very high, for using the stereometry of 1ml standard pipettes,
Precision can reach 0.01cm3.
Measuring targets of the present invention are Non-destructive samplings；No matter whether the proportion of object under test is more than water, can be used
The present invention realizes the accurate quick measurement of volume.
