在物理实验教学中,经常会遇到要演示一些变化效应微弱的物理现象,为使实验效果明显,可见度大,通常要采用放大手段.物理实验中常用的放大手段或方法有杠杆放大,光点反射放大,点光源投影放大,投影仪放大,弱电流放大等.本文主要谈谈几种“微小形变”演示实验的放大设计.1反射光点?
In physics experiment teaching, we often encounter to demonstrate some of the weak effects of changes in the physical phenomenon, in order to make the experimental effect is obvious, the visibility is large, usually to use amplification means.Experiments commonly used in physics amplification means or methods of lever amplification, light point Reflection amplification, point light projection enlargement, projector magnification, weak current amplification, etc .. This article mainly talks about several kinds of “small deformation” demonstration experiment amplification design.1 Reflected light point?
