The relationship can be expressed by a linear equation of windinglength and thickness versus drape behavior.
织物弯曲长度、 厚度等与织物悬垂性可以线性方程表达。

For such a low frequency, which would only be resorted to when it is indispensable for the operation of ordinary motors, I would use a secondary winding wound from a wire 50 miles in length.
The propagation process of pulse wave in the cable and influence of cable length on overvoltage and wavefront time of winding are discussed in this paper.
