set piston

Get lathe No.9 set to turn the new piston.

把九号车床调好来车这个新活塞。

Aiming at solving the present problems, we proposed a new method to set up and analyze work flow model when we finished the project of developing "piston PDM system based on WEB". This method is based on UML state machine-PNs integration.

基于当前工作流建模存在的问题，我们在完成山东省科技厅项目基于WEB的活塞PDM系统的研发过程中，提出了一种基于UML状态机-PNs集成的工作流建模与分析方法。

According to the thermal loading conditions of piston, a mathematical model for piston thermal shock problem was set up on the basis of the hyperbolic conduction equation proposed by R. M. Morse and H. Feshbach, and was solved by Laplace transform method.

摘要本文依据活塞受热特点，以R M Morse和H Feshbach提出的双曲线型导热方程为基础，建立了一种分析活塞热冲击问题的数学模型，并利用拉普拉斯变换对其进行求解。
