And, depending upon, say the density of the gas or the liquid, the size of the molecules, they change parameters in the simulation, how far it, say, goes in each unit time and things like that.

这还取决于，比方说，液体或气体的密度，分子的大小，它们改变了模拟程序中的参数，它们在一个时间单元内运行的距离，或者之类的。

One of the effective ways to improve the area recording density of magnetic media has been to reduce the size of recording unit.

信息存储用磁性介质的记录面密度的不断提高，主要途径之一就是减小磁性颗粒的尺寸。
