但是，由于视觉识别对色彩和长度等图形要素定量分辨的精度非常有限，因此，直接从图形上很难准确地解读出所表现的物理函数的精确值。

But because of the limit of distinguishing ability of?human's?eye, it is difficult to get accurate understanding of values of functions by reading from colors of the pictures directly.

例如，您可以使用填充函数来填充数组，这对于物理模型来说非常有用。

For example, you can populate arrays based on populating functions, which is likely to be useful for physical models.

如果我们从物理意义或者,概率密度的角度来看这个问题，我们需要把波函数平方。

So again if we look at this in terms of its physical interpretation or probability density, what we need to do is square the wave function.

If you have a quantity which is constant over any closed path, that quantity is a thermodynamics state function.

如果有一个物理量,对任何闭合回路积分是常数，这个物理量就是一个热力学态函数。

So, we're talking about wave functions and we know that means orbitals, but this is -- probably the better way to think about is the physical interpretation of the wave function.

我们讨论波函数而且,我们知道它代表着轨道，但-也许更好的思考方法是,考虑波函数的物理意义。

We'll then look at the quantity, internal energy, which we define through the first law, and we think of it as a function of two variables T and V.

接下来我们考虑内能，这是由热力学第一定律定义的物理量，我们把它看作T和V的函数。
