第一个方法返回可枚举对象而不是实际的函数结果。

The first returns an enumerable object instead of the actual result of the function.

这确保调用者适当地检验函数结果，从而能够适当地处理错误。

This ensures that callers are properly validating the function result so that they can handle the appropriate errors.

本文通过对锚泊非线性水动力系统进行分析，首次将两种方法取得的频率响应函数结果进行对比。

In this paper, the frequency response functions obtained by using these two methods are first compared through analysis of non-linear mooring system.

It turns out there's a new function strlen S-T-R-L-E-N that you probably have not used yet called strlen, S-T-R-L-E-N, programmers early on and still like to be succinct but communicates sufficiently what they mean.

结果这里有个新的函数,你可能没有使用过，叫做，早期的和现在的程序员喜欢简洁地,但是能充分的传达他们的意思。

So again, for both heat and work we don't get the same result. Now let's look at our special function, right. So here's path A.

所以，再一次说明，对于热量和功,我们得到的结果是不同的,现在让我们看看我们的特殊函数。

But it turns out that as we'll see that functions absolutely take arguments, right?

但结果是我们将看到,函数绝对是有参数的，对不对？
