通过自动编程系统可将激光切割的CAD图形自动转换为加工代码，并可自动选择最佳切割顺序，保证最短空程路径；

The automatic programming system can translate the CAD drawing to processing code , optimize the working procedure and processing path .

尤其是碰撞中产生的源的时空信息，由于源存在的时间非常短，空部尺度非常小，所以只能由实验末态可观测量间接地加以推测。

For short lifetime and little space extend , the space-time information of the source created in the collisions must be deduced by final observable quantity .

与野生型相比，沉默株系ABD株高变矮，叶片变短，出现白色空秕谷。

Compared with the wild type , the down-expression lines ABD showed reduced plant height , shorter leaf , white blighted grain .
