Description
Technical field
The present invention relates to a kind of teaching aid, the body demonstrator such as in particular to a kind of laughable Sprite mixing.
Background technology
On liquid hybrid solving problem in teaching, usually teacher explains principle, student's rehearsal exercise, teaching process list
One, student thought is limited, and teaching method is single, with actual mixed process without contacting, it is difficult to which training student working knowledge is solved
The ability of practical problem, to break through conventional teaching drawback, so have this invention.
The content of the invention
The purpose of the present invention is that there is provided a kind of body demonstrators such as laughable Sprite mixing for problem above.
The solution of the present invention is realized by following technological means：A kind of body demonstrators such as laughable Sprite mixing,
Including tank（1）, graduation mark（2）, pull bar（3）, dividing plate（4）, scale（5）, it is characterised in that：Tank（1）It is that a upper end is opened
The transparent vessel of the rectangular shape of mouth, tank（1）Bottom, top and side have graduation mark（2）, dividing plate（4）Tank（1）
It is divided into left and right two parts, dividing plate（4）With pull bar（3）It is fixedly connected, pull bar（3）Two ends pass through tank（1）Left and right sidewall and and side
Wall is in close contact, scale（5）It is close to tank（1）Outer wall and and tank（1）Base it is parallel.
The dividing plate（4）With tank（1）It is in close contact, left and right pulls pull bar（3）, can be with dynamic dividing plate（4）In tank（1）In
Move left and right, so as to change tank（1）The volume of the right and left, tank（1）The right and left adds liquid and will not mutually mixed.
The tank（1）On graduation mark（2）All with tank（1）Each side it is vertical, interval is all uniform, bottom scale
Line（2）Scale total length be 1, the graduation mark on top（2）It is identical with bottom.
The scale（5）Can parallel tank（1）Base upward-downward translation, scale（5）Start movement be from liquid level downwards,
Displacement is equal to liquid level value and the product of vertical clapboard indicated number.
The present invention has larger help to training student thinking ability, has the advantages that easy to operate, visual phenomenon.
Although the preferred embodiments of the present invention are described above in conjunction with accompanying drawing, the invention is not limited in upper
The embodiment stated, above-mentioned embodiment is only schematical, be not it is restricted, this area it is common
Technical staff in the case of present inventive concept and scope of the claimed protection is not departed from, may be used also under the enlightenment of the present invention
To make the specific conversion of many forms, these are belonged within protection scope of the present invention.
Brief description of the drawings：
Accompanying drawing 1 is elevation cross-sectional view of the invention；
Accompanying drawing 2 is left view of the invention；
Accompanying drawing 3 is top view of the invention.
Wherein：1-tank, 2-graduation mark, 3-pull bar, 4-dividing plate, 5-scale.
Embodiment：
Below in conjunction with brief description of the drawings, the present invention is described in further detail with embodiment：
As illustrated, a kind of body demonstrator such as laughable Sprite mixing, including tank 1, graduation mark 2, pull bar 3, dividing plate 4, mark
Chi 5, it is characterised in that：Tank 1 is the transparent vessel of the rectangular shape of a upper end open, bottom, top and the side of tank 1
While there is graduation mark 2, tank 1 is divided into left and right two parts by dividing plate 4, and dividing plate 4 is fixedly connected with pull bar 3, and the two ends of pull bar 3 pass through tank
1 left and right sidewall is simultaneously in close contact with side wall, and scale 5 is close to the outer wall of tank 1 and parallel with the base of tank 1.
The dividing plate 4 is in close contact with tank 1, and left and right pulls pull bar 3, can be moved left and right with dynamic dividing plate 4 in tank 1,
So as to change the volume of the right and left of tank 1, the right and left of tank 1 adds liquid and will not mutually mixed.
Graduation mark 2 on the tank 1 is vertical all with each side of tank 1, and it is all uniform to be spaced, bottom graduation mark 2
Scale total length is 1, and the graduation mark 2 on top is identical with bottom.
The scale 5 can parallel tank 1 base upward-downward translation, scale 5 start movement be from liquid level downwards, it is mobile away from
From the product equal to liquid level value and vertical clapboard indicated number.
Application method：The body demonstrators such as laughable Sprite mixing are placed in horizontal table top, body is separately added into two cups
Product it is equal can happy Sprite, the cola that volume is V is taken out from laughable cup, the body demonstrator water such as laughable Sprite mixing are poured into
The left side of groove 1, then all Sprites in Sprite cup are poured into the right side of tank 1；Pull bar 3 is pulled, until the liquid level phase of the both sides of dividing plate 4
It is flat, liquid level value h is read, the indicated number a of vertical clapboard 4 is read, scale 5 is moved down since liquid level, displacement c is equal to
The liquid level value h and indicated number a of vertical clapboard 4 product；Then with pipettor by all of above liquid of scale 5, move into laughable
In cup, remaining liq refunds sky Sprite cup；Then the Sprite volume in laughable cup and the laughable volume phase in Sprite cup
Deng.
Principle：If the thickness of tank 1 is d.Mobile pull bar 3, it is laughable in horizontal direction when the liquid level of the both sides of dividing plate 4 is equal
It is that equivalent uniform is mixed with Sprite, and volume V=ahd；Mobile scale 5, displacement c=ah, then V=ahd=1 × ah × d=
1 in 1 × c × d, 1 × c × d, it is the scale total length of bottom graduation mark 2, the body demonstrator such as laughable Sprite mixing is intuitively shown
It is V to go out the liquid volume that height is c, intuitively shows V=a（h-c）D+acd, intuitively show V=（1-a）Cd+acd, so that directly
Sight shows a（h-c）D with（1-a）Cd is equal, it is, being c by the level above of scale 5, volume is moved back into for V liquid can
In happy cup, remaining liq is refunded in sky Sprite cup, the volume of Sprite and volume laughable in Sprite cup in laughable cup
It is equal.
