the law of conservation of angular momentum是什么意思

用法例句

Angular momentum feedback control for flexible spacecraft;

挠性卫星姿态的角动量反馈控制

2-rank tensors of angular momentum ladder operators;

二秩角动量阶梯算符张量

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.

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。
