So, again we can use these probability density plots, which are just a plot of psi squared, where the density of the dots is proportional to the density, the probability density, at that point.

同样的我们可以利用这些概率密度图，这是psi的平方的图，这里面点的密度，正比于概率密度。

The square modulus of the wave function is proportional to the probability density of finding the system at each point in the configuration space.

波函数的模平方正比于体系处在其位形空间各个点的几率密度。

We have found that the complex density was directly proportional to the length of the reaction pad as well as the number of pads even if total length was kept constant.

我们已经发现结合物的浓度与反应垫的长度和反应垫的数量，如果长度不变的话，有直接的比例关系。
