On Designation and Application of Multi-Function Electrostatics Experiment Device

实验装置通过一对带电平行金属板形成匀强电场,由可控带电液滴装置提供带电粒子,整个装置封闭在一个外壳中.该装置可以演示带电粒子在匀强电场中的加速、偏转现象,探究带电粒子在匀强电场中偏转运动的偏转量与哪些因素有关,探究平行板电容器的电容与哪些因素有关等.阐述了装置的原理,分析了装置的构成及其在教学中的应用方法.

An experiment device has been formed by a pair of charged parallel plates,provided charged par-ticles by the controllable device charged water droplets,and the whole device has been enclosed in a shell. The experimental device shows charged particles acceleration and deflection phenomenon in uniformly strong electric field,and charged particles deflection quantity concerning the factors of the deflection movement in the uniform strong electric field,and capacitance of plane-parallel capacitor concerning relat-ed factors.It also describes principle of the device,introduces designing,demonstrating and using meth-ods of the device in teaching.
