摘　　要： 本实验是基于调制电场原理,结合密立根实验,从能量守恒的角度出发来测量微电量.在两极板间加平衡电场使碳粒平衡,再添加调制电场,在调制电场作用下碳粒做振幅为A的振动.取碳粒从最低点运动到最高点这个过程,根据动能定理可推导出q的表达式. Our experiment is to measure micro charge based on the law of conservation of energy ,com bined with MIllikan experiment .Add a balanced electric field to make a carbon particle balanced ,then add a modulated electric field to make the carbon particle to vibrate with an amplitude of A .The progress the particle vibrates from the bottom to the highest point is the point we need to consider ,and then we can determine the expression of q according to the theorem of kinetic energy .
