Abstract
The utility model discloses an atomic absorption teaching demonstration model. The atomic absorption teaching demonstration model comprises a demonstration platform, a hand-operated demonstration apparatus and a process model. According to the utility model, by means of a moving side plate, energy magnetons and atomized atoms are subjected to energy level differential matching combination on a main board, thereby achieving the purpose of demonstrating energy level transition, and the process of demonstrating light source reduction is controlled by an up-down moving sliding plate. The model provided by the utility model can vividly demonstrate the process of atomic absorption, being suitable to be widely used for teaching.
Description
Technical field
The utility model relates to a kind of teaching mode, relates in particular to a kind of teaching mode that the Atomic absorption process is demonstrated.
Background technology
The Atomic absorption principle has widespread use aspect identification and the qualitative and quantitative analysis material, but the process of Atomic absorption is difficult to understand, owing to there is not teaching mode, so the teacher usually explains with bookish literal in the teaching, but inadequate image, be difficult to make the student more deep, thorough understand content.
The utility model content
The utility model purpose is the blank of replenishing the Atomic absorption teaching mode, this model can be demonstrated before plate, the magnetite sheet of being with represents different wave length energy and ground state atom, side plate moves demonstration energy level transition process, sliding up and down the plate demonstration light source reduces, the atomization district is with molecular atoms, and is not only simple to operate, is convenient to understand.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of Atomic absorption demonstration model for teaching comprises the combination of atomizer, the distribution of transition energy level, atom and coupling energy, control plate moving up and down, main floor, energy side plate.Base plate is provided with a plurality of functional areas, has many hollow outs rectangular on the main areas, posts isometric iron bar between the space.Iron bar is marked with energy level and distributes, and side plate energy magneton is arranged side by side, in the moving process, with the energy of atomic transition energy level coupling by Atomic absorption, rectangular by hollow out, in conjunction with adhering to iron bar energy level district, dump energy shifts out with the side plate right side, up and down removable district's regulation and control energy side plate size variation.
The present invention can demonstrate the Atomic absorption overall process, conveniently clearly demonstrates overall flow, and is simple to operate, is beneficial to understand and master, is desirable Atomic absorption teaching mode instrument.
