而粒度均值曲线与冰心及石笋氧同位素曲线的差异，一方面可能是由于地理位置的差异，另一方面可能与当时太阳辐射变化情况以及季风作用有关。

Then through dynamical analysis, every instantaneous acceleration distributing of slope under dynamical earthquake can be got too. According to this result, adding earthquake force to structure by way of inertial force, this paper analyses the slope stabilization by using FEM strength reduction method and gains every instantaneous safety factor and its corresponding slide. Curves of safety factors versus duration can be made by curvefitting. By safety factors versus duration curves and slides, we can value structure's quakeproof stabilization and point its slide out. By these principles, programs of FEM stabilization analysis for each moment are organized.
