查询词典 lubricational

By designing different test rigs, choosing different friction materials and performing a large amount of tests, the property of friction with respect to the variation of normal loads, relative velocities and lubricational conditions is examined.

通过设计不同的测试装置，采用不同的摩擦材料，通过大量的实验，测试并分析了摩擦力随接触界面间正压力、相对速度、润滑状态变化的情况，研究了摩擦力在预滑动和宏观滑动阶段的静态及动态摩擦特性，发现并提出摩擦过冲概念。

A two-dimentional isothermal transient full film and part film EHL model has been established, which is used to analyze lubricational behavior of cam-tappet pair of valve train. Using mulit-gird method, the oil film status during intake duration could be investigated with the consideration of dynamic effect. The influences of surface roughness are also taking into account in the part film model.

建立了配气凸轮-挺柱副润滑油膜分析的二维等温瞬态全膜及部分膜模型，运用多重网格法进行计算，结合动力学计算模型分析了从进气门开启至关闭期间油膜状态的变化，并在部分膜润滑下考虑了表面粗糙度对其影响。

Means the parent directory, so this command means to execute "toolchain.sh," which is in the current directory.

代表父目录，所以这个命令就是执行当前目录下的"toolchain.sh"。

Yes,In fact,I'm on our city ream.

是的。事实上我是我们市队的。
