结果表明，活塞面积和蓄能器体积对系统性能影响比较大，而活塞最大行程和油液弹性模量对系统性能影响较小。

The result show that the piston area and the accumulator volume have more influence on the system 's performance, and the piston stroke...

结果表明，与圆形、方形活塞的辐射远场相比，在声波频率、活塞面积相同条件下，六边形活塞声源的辐射远场相对比较均匀。

Through comparison, it shows that at the same value of frequency and size, the far field of hexagonal piston is more uniform than that of circular piston.

And so we know the force for a particular mass, and we know the area of the piston.

我们知道每个质量对应的力，也知道活塞的面积。
