动量

Angular momentum can accompany nonrotational motion.

非旋转的运动可伴随着有角动。

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

那些具有的变(如动位置,或时间)是经典力学里的正则共轭变。

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，太阳风只靠磁层顶上的波动，来动给地球四周的电浆。
