Use geometry or you need to set up for double integral of a surface.

总之，就是用几何方法或是在曲面上建立二重积分。

Double integral of F.dS or F.ndS if you want, and to set this up, of course, I need to use the geometry of the surface depending on what the surface is.

就是做F·dS或是F·ndS的二重积分，为了能建立积分，需要用到曲面的几何性质，这与该曲面的类型有关。

Varying the geometry allows the pair to discern better the signal they see from different types of surface.
