An interacting—and complicating—phenomenon is wind-to-water transfer of momentum that occurs when waves are formed.

一种相互作用且复杂的现象是波浪形成时发生的风向水的动量传递。

He is adamant that this is not a perpetual motion machine, and does not violate the law of conservation of momentum because different reference frames apply to the drive and the waves within it.

他坚持认为这并非永动机，也没有违反能量守恒定律，因为驱动器和里面的微波使用不同的坐标系。

Wind waves and atmospheric turbulence were measured in the experiment of wind wave momentum transfer.

在风浪槽中进行水气动量交换实验，测量了不同风速和风区下的波浪及空气湍流流场。

Current wireless protocols alter the spin angular momentum (SAM) of radio waves to hold info, and by combining both methods the team was able to pack eight data steams into a single signal, resulting in the mouth-watering number noted above.

With a modest investment in time and data collection, investors can use ETFs to surf those waves of capital, taking advantage of a well-known phenomenon in the markets called "momentum, " or "relative strength, " in which rising shares tend to keep rising for three months to a year after they start their run.
