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。
Residual coding is even more difficult to understand than motion vector coding, as the only full reference is a bunch of highly optimized, highly obfuscated C code.
剩下的编码甚至比运动矢量编码更难理解，因为唯一的完整参考是一堆高度优化的，高度混淆的C代码。
Many textbooks have derivations of the equations of motion. We list some below. The discussion in Reference 3 (indeed the whole book) is very clear.
很多教科书都有运动方程的推导。在下面我们列举了一些。参考文献3(实际上是整本书)中的讨论是十分清楚的。
