中性点位置 meaning in English

neutral-point position

In the same time we let the relative displacement be zero
同时令相对位移为零可得出中性点位置。
The factors that cause negative friction are discussed . the mechanism of negative friction and the methods decreasing it are also studied . the neutral point and negative friction are determined according technical code for building pile foundation
