volume viscosity的意思|示意

The results indicate that the temperature dependence of ultrasonic attenuation in liquid hydrogen is mainly determined by volume viscosity effect.

实验结果表明，液氢的超声衰减的温度依赖特性主要取决于体积粘滞效应。

Similarly, for the twin-screw pump, the fluid viscosity smaller than the viscosity of the liquid leakage is smaller, leakage volume and viscosity of a certain percentage of media relations.

同理，对于双螺杆泵，粘度大的流体比粘度小的液体的泄漏要小，泄漏量与介质粘度有一定的比例关系。

This phenomenon is explained by free volume and viscosity theory.

用粘度和自由体积理论解释了此现象。
