The variation and transmit of the radial and tangential energy flow in the air gap of electrical machines are illustrated by analyzing the divergence of Poynting vector.
通过对坡印亭矢量的散度的分析，阐明了电机气隙中径向能流和切向能流的变化和传递。

Therefore the maximum of the radial energy during the P-wave arrive appears in the direction of the first singular vector.
In this paper we discuss the important parameter the ocean surface current and raise an algorithm to generate the vector current map in terms of data from two pieces of radial current map.
