The results show that: with the initial principal stress direction angle increases, the axial residual deformation from the compression state gradually transits to the elongation.
结果表明：随着初始主应力方向角的增大，轴向残余变形由压缩状态的正值逐渐过渡到伸长状态的负值。
In establishing residual limits, it may not be adequate to focus only on the principal reactant since other chemical variations may be more difficult to remove.
在确定残留物限度时，也许只是集中注意主要的反应物做得并不够，因为也许有别的化学变异产物更难以除去。
