The effect of the first normalstressdifference increases the load capacity obviously under the condition of the dynamic load, and it also affects the locus of shaft center.
在动载荷条件下，第一正应力差效应明显增强了油膜压力和承载力，并对轴心轨迹产生影响。

The bubble shape is changed gently because of the difference between radius of geometric curvature and radius required to equalize normalstress.
