So the first thing is, let's approximate that we could take the sum not to some finite level, which would be the case if there's a finite number of elements in the chain.

那么第一件事，让我们估算它们的和，不是对有限能级求和，有限能级适用于，分子链中有有限数目的结构单元的情况。

This one is, because there's a finite number, four in this case, of configurations.

这一个因为是有限的数目，在这种构型的情况下。

In this case, we need to truncate the domain to obtain a finite domain for performing numerical calculations.

在这种情况下，我们需要将这无限的区域截断成有限的区域来进行数值计算。

First, because commodity backed currencies (in this case gold) are basically tied to a finite resource that can not be counterfeited, a deflationary economic environment is created.
