| Abstract: | The demonstrative meter of thermal expansion and contraction of solid is made of a metallic hoop and a metallic ball.In this paper,we introduce a new synthesis-demonstration meter of thermal expansion and contraction of solid based on more exploration of physical principle of the demonstration experiment,which uses the characteristic of thermal expansion contraction of solid as the switch of the passing or breaking to the laser circuitry,and also uses the amplification function of the light path to minim ap... |
