Momentum of particle的意思|示意

The cranking term breaks the time reversal symmetry, and the projection of the single particle angular momentum on the intrinsic symmetric axis is no longer a good quantum number.

推转项的引入破坏了时间反演对称性，单粒子角动量在内禀对称轴上的投影量子数已不再是好量子数。

The nonequilibrium statistical operator (NSO) of the system is constructed and a series of macroscopic equations for its particle number, momentum, energy, force aad entropy etc. are derived.

构成了此体系的非平衡统计算符，进而导出其粒子数、动量、能量、力和熵等一系列宏观方程。

Using Lorentz transformation, a momentum vectors diagram of the emitted particle in laboratory frame and center-of-momentum frame is given in relativistic two-body reaction.

利用洛伦兹变换，画出了相对论下二体反应实验室系和动心系出射粒子动量的关系图，并利用关系图，对不同情况下的出射粒子能量分布作了讨论。

What is the momentum of particle number one?

物体1的动量是多少？

And we'll also talk about photon momentum as another example of light behaving up as a particle.

并且我们也会讨论光子动量的问题，这个可以作为光有粒子行为的例子。

Particle collisions are the main mechanism of the momentum transfer, the energy transfer and the energy dissipation for rapid granular flows.

颗粒碰撞是快速颗粒流的动量传递，能量传递及耗散的主要机制。
