中低山坡地土壤质量的变化特征主要依赖于土地利用与覆盖之间的差异。

The distribution configuration of middle-low mountain soil quality mainly depends on the variations between land use and cover, and human activities is the main factor that enhances the variations.

We have a table of the elements with properties varying periodically with atomic mass, so we compress all of that information and refer to it as the Periodic Table.

我们有一个元素表，其中的元素的特性,随着原子质量的改变而引起周期性的变化，所以我们将所有的信息精简,将它变成一个周期表。

And since we are not expecting the mass of the particle to change, what we really are saying is the uncertainty in its velocity times the uncertainty in its position is greater than the ratio of the Planck constant divided by 2 pi.

因为我们不期望,粒子质量发生变化，我们说的是,它速度的不确定度,乘以它位置的不确定度,比普朗克常量,除以2除以圆周率要大。
