This paper deals with the eddy currents on the vacuum vessel of fusion devices. The eddy currents on the vessel are considered as surface currents and described by the normal components of a vector.

本文研究了聚变装置真空室上的涡流问题，将真空室上的涡流看作面电流密度并定义一矢势的法向分量来描述它。

I gave you a law of transformation of the components; namely, if the vector has components Ax and Ay in one reference frame and Ax prime and Ay prime in another reference frame, how are the two related?

我介绍过分量变换的法则,即如果矢量在一个坐标系的分量为 Ax 和 Ay,在另一坐标系中的分量为 Ax' 与 Ay',它们有着什么样的联系
