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。

That would that would give rise to a perpetual motion machine, breaking of the second law. It can't happen.

否则就会使，得永动机出现，打破第二定律那是不可能的。

Arguments based on the impossibility of perpetual motion can be used to support Newton's third law of mechanics.

以承动机的不可能实现为基础的论据，也可用以支持牛顿第三运动定律。
