动量

Angular momentum can accompany nonrotational motion.

非旋转可能伴随着有角量。

Those variables for which it holds (e.g., momentum and position, or energy and time) are canonically conjugate variables in classical physics.

那些具有变量(如量与位置,或能量与时间)是经典力学里正则共轭变量。

According to this hypothesis, the solar wind could transfer energy and momentum to the plasma surrounding the earth only by wave motions along the magnetopause.

根据项假说，太阳风只能靠磁层顶上波，来传递能量与量给地球四周电浆。
