Both nucleation and growth are affected by the external stress by two-step aging simulation, but the effect degree depends on lattice misfit.

采用双级时效模拟方式时，外加应力场对析出相的成核及生长阶段均有影响，只是影响程度与析出相自身的点阵错配度有关。

In the case of considering the misfit dislocation, relaxed lattice mismatch, the radius of curvature and density of misfit dislocation were calculated.

在考虑存在失配位错的情况下，计算了驰豫晶格失配、曲率半径和失配位错密度。
