高速运动质点的4-角动量

4-angular Momentum of the High-speed Particle

高速运动质点的4-角动量表示成张量Jμv的形式,通过对Jμv进行洛伦兹变换可以得到3维角动量L的变换关系以及辅助量G的变换关系,在经典过渡下,前者与角动量的伽利略变换相符合,后者恰好反映加速度a是伽利略变换的不变量.

By expressing 4-angular momentum of the high-speed particular in the form of tensor,and by Lorentz transformation,we can get the conversion equation of 3-dimension angular momentum and auxiliary vector.Furthermore,by the classical transition,the former is in accord with Galilean transformation,the later is in accord with the invariance of acceleration of Galilean transformation.
