Abstract
The utility model discloses a definite integral teaching aid. The technical problem of the utility model is to provide the visual definite integral teaching aid used for facilitating the understanding of the students about the definition of the definite integral. In order to solve the above mentioned problem, the definite integral teaching aid comprises a bottom plate made of transparent materials. The definite integral teaching aid is characterized in that the bottom plate is provided with an abscissa rod and an ordinate rod, which are vertically connected together, and a curve top disposed on the top end of the ordinate rod; a group of interval vertical rods capable of moving leftwards and rightwards are disposed between the abscissa rod and the curve top; an interval horizontal rod capable of moving upwards and downwards is disposed between every two interval vertical rods; and the abscissa rod is provided with verniers capable of moving leftwards and rightwards. The definite integral teaching aid has advantages of simple production, low costs, convenient operation, strong visual performance, and abilities of reducing learning difficulty, raising learning interests of students, and improving classroom teaching quality.
Description
Technical field
The utility model relates to a kind of teaching aid, particularly a kind of definite integral teaching aid.
Background technology
Definite integral is a more abstract mathematical concept in higher mathematics, and teacher is lecturing higher mathematics class hour now, explains for general, usually because not intuitively make student be difficult to fast understanding on blackboard with word or simple drawing.
Utility model content
The technical problems to be solved in the utility model is to carry a kind of definite integral teaching aid that makes intuitively student manage fast definition of definite integral.
For addressing the above problem, the utility model adopts technical scheme to comprise the base plate that transparent material is manufactured, it is characterized in that: described base plate is provided with horizontal ordinate bar connected vertically, ordinate bar and the curve top of ordinate bar upper end is set, between described horizontal ordinate bar and curve top, be provided with one group of interval vertical pole that can move left and right, between every adjacent interval vertical pole, be provided with interval cross bar moving up and down, described horizontal ordinate bar is provided with the vernier that can move left and right.
Described definite integral teaching aid, is characterized in that: described interval vertical pole, interval cross bar are expansion link, and described interval vertical pole can do expanding-contracting action with the curve height at curve top, and described interval cross bar can do expanding-contracting action with adjacent interval vertical pole spacing.
Described definite integral teaching aid, is characterized in that: described interval vertical pole is provided with scale.
Described definite integral teaching aid, is characterized in that: described interval vertical pole and vernier adopt different colours to distinguish.
Described definite integral teaching aid, is characterized in that: described vernier is spherical.
Described definite integral teaching aid, is characterized in that: described interval vertical pole takes on a red color, and described vernier is black.
Described definite integral teaching aid, is characterized in that: described vernier quantity is 8-10.
Definite integral teaching aid of the present utility model, has and manufactures the advantages such as simple, cost is low, easy to operate, intuitive is strong, has reduced learning difficulty, has improved student's learning interest, thereby has improved Classroom instruction quality.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Constitutional diagram when Fig. 2 is the utility model demonstration;
Fig. 3 is interval vertical pole structural representation;
Fig. 4 is interval bar structure schematic diagram.
Embodiment
As shown in Figures 1 to 4, definite integral teaching aid of the present utility model, comprise the base plate 1 that transparent material is manufactured, described base plate 1 is provided with horizontal ordinate bar 2 connected vertically, ordinate bar 3 and the curve top 4 of ordinate bar upper end is set, between described horizontal ordinate bar 2 and curve top 4, be provided with one group of interval vertical pole 5 that can move left and right, between every adjacent interval vertical pole, be provided with interval cross bar 6 moving up and down, described horizontal ordinate bar 2 is provided with the vernier 7 that can move left and right.
Described interval vertical pole 5, interval cross bar 6 are expansion link, all have outer bar and interior bar, and interior bar stretches in bar outside.Described interval vertical pole 5 can do expanding-contracting action with the curve height at curve top 4, and described interval cross bar 6 can do expanding-contracting action with adjacent interval vertical pole spacing.Described interval vertical pole 5 is provided with scale.Described interval vertical pole 5 adopts different colours to distinguish with vernier 7.The most desirable, for described interval vertical pole 5 takes on a red color, described vernier 7 is black, and quantity is 8-10., with different color differentiatings, in order to allow, student is convenient clear sees position relationship clearly, makes in understanding.Described vernier 6 is spherical being convenient to and moves.
When demonstration, interval vertical pole and vernier are moved right, then will on interval cross bar, move, in the time that mobile interval cross bar is more, cut apart when thinner, rectangular parallelepiped group area and dianegative that all interval cross bars surround are more approaching.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within being all included in protection domain of the present utility model.
