为降低粒子量和改善生产量提供恒定的1.0-0.2的粒子过滤，有效的降低了酸耗量。

The MODUBATH?F Series will significantly reduce acid consumption while providing continuous 1.0 to 0.2 micron filtration for reduced particle count & improved yields.

在普通力学中，如果不关注大量粒子的熵，诸如此类的物理量的话，这就是我们通常见到的结果。

And this is the familiar result from ordinary mechanics, where you're not worrying about something like entropy for a whole collection of particles.

And this spin is an intrinsic quality of the electron, it's a property that is intrinsic in all particles, just like we would say mass is intrinsic or charge is intrinsic.

自旋是电子的本征量，它是所有粒子的本征性质，就像我们说质量是本征的或者电荷是本征的。
