The results show that SDV could not be detected in old leaves and stem barksall over the year.
结果表明SDV在老叶、老枝皮中全年均检测不到；

It takes design experiment samples by orthogonal plan method and regards the SDV values which come from soft trying die as goal of optimizing.
其中由正交法设计得到实验样本，由软试模提取模具的SDV值，将其作为优化目标。

The non-homogeneous metal flow during the extrusion forming process was well controlled by introducing a non-equilibrium parameter of metal flow, the mean-square deviation of velocity (SDV).
