摘　　要：利用洛仑兹变换,导出匀速运动带电粒子的电磁场;根据洛仑兹力公式,推出匀速带电粒子的相互作用力.从电磁动量、动量守恒、动量定律与力之间的联系出发,分析阐述了运动带电粒子间的相互作用力不一定服从牛顿第三定律.The electromagnetic field induced by charged particles with uniform motion is derived from the Lorentz transformation. The electromagnetic force between charged particles with uniform motion is de duced accordingly to Lorenz force equations. The thesis, by investigating the electromagnetic momentum, momentum conservation law in electromagnetic field, and the relationship between electromagnetic force and momentum theorem, analyses and illuminates why the interaction force between two moving charged particles is not always accord ance with Newton third law.
