So, one possibility would be that your fluid is actually being compressed or expanded.

一种可能性就是，流体被压缩或是膨胀了。

Two small pouches, placed in the bottom of a shoe, are filled with the fluid and generate a current whenever they are compressed by the foot’s up and down motion.

当他们将两个装有该流体的小袋子置于鞋内时，它们就会因人脚抬升和下落的动作而受到挤压，从而产生电流。

According to the fractal geometry theory and the non-compressed viscous fluid laminar flow theory, the leakage model of metallic gasket based on fractal parameter was established.

依据分形几何理论，结合不可压缩粘性流体层流流动理论，建立基于分形参数的金属垫片泄漏模型，该模型揭示了泄漏率与密封表面形貌之间的关系。
