摘　　要：无外场时,转动参照系中的物体受到惯性离心力、科里奥利力和横向力的作用。转动参照系中的惯性离心力与运动电荷受到的电场力等价,两者都是保守力;科里奥利力与磁场力等价,两者都不改变运动物体的动能;而转动参照系中的横向力与惯性系中的感应电场力类似。研究结果表明力学与电磁学具有相似性,相对性原理是正确的。In the absence of external fields,the objects in rotating reference frames are exerted force by centrifugal force of inertia,Currie Ollie and lateral forces.Inertial centrifugal forces of rotating reference frames and electric forces of the moving charges are equivalent,both of which are conservative forces;Curry Ollie forces are equivalent to magnetic forces,and both of them never change the kinetic energy of the moving objects;The lateral forces are similar to the induced electric field forces of inertial system.The results show that mechanics and electromagnetism have similarity,and the principle of relativity is correct.
