The net result is this: Overall perceived judder that originates from 3:2 pulldown is eliminated with 5:5 pulldown.

最终的结果是：总认为抖动，从3：2下拉起源是5：5淘汰下拉。

Second, by analyzing the strain of northsouth blocks of the fault, we find an asymmetric displacement distribution between the two sides of the rupture, and the two blocks are subject to compressional and tensional stress respectively. It is a pattern that cannot be explained with the linear elastic theory. However, laboratory experiments and in situ measurements in boreholes have shown that many crustal rocks exhibit a nonlinear elastic behavior in compression and tension with a dependence of the Young's modulus on the minimum principal stress. So we suggest that the nonlinear displacement distribution should be considered when dislocation and hypocentral parameters are analyzed.

进而通过对地震南北盘同震应变的分析，发现了昆仑山地震的南北两盘分别受挤压和拉张两种应力作用，研究表明多种岩石在拉张和压力作用下其最小主应力下的杨氏模量表现出非线性弹性特征，从而提出对昆仑山地震地表位移及震源特征参数分析时应考虑非线弹性介质导致的非线性弹性位移分布特征。
