the shortening period of tumors after unilateral nephrectomy might help to provide a better model for chronic animal experiment.
因为这一方法可以明显缩短引癌的周期,有可能作为整体慢性诱癌实验一个改良的模型。
for the sake of reducing cost, shortening period of design, manufacture, in- stalling and debugging, standard impact molding system has been exploited.
为了降低成本,缩短设计、制造、安装调试时间,开发了标準沖击造型系统。
therefore, it is significant to implement parametric 3d solid modeling and engineering drawing for improving quality of design, shortening period of design, reducing cost and realizing cam.
