By strong fluctuation stimulation of a proper initial function the frequency-lockingeffect is observed not only in P_2-wave, but also in P_4 wave.
适当初函数的强扰动激发不仅在P_ 2波观察到锁频效应，在P_ 4波也证实了锁频效应的存在。

In order to reduce the intractable shear lockingeffect, a macro triangular partition shell element is formed with three individual sub-triangular domains.
针对剪切闭锁效应，本文引入一种基于假设自然应变方法的宏观三角形分区平板壳单元。

What's more, when a vibration test was performed in this condition, no loosening occurred, indicating that a self-lockingeffect is present even if the nut is not fully tightened.
