coefficient of pressure diffusion的意思|示意

Permeability of concrete and its correlation with chloride ion diffusion coefficient under different test conditions including water pressure method and tension method are studied.

本课题主要研究混凝土在水压法及张力法试验条件下水在混凝土中的渗透行为以及同氯离子扩散系数相关性。

The increase of lobe diffusion angle results in the increase of velocity circulation at the lobe exit section, but it raises the mixing loss and lowers the pressure recovery coefficient.

扩张角的增加可提高速度环量，但是流动混合损失增加，总压恢复系数减小。
