Let us take a look at our simple doIt example with a bit of parametric typing thrown in (in Listing 3).

下面我们来看一个简单的doIt例子，它使用了一些参数类型化(见清单3)。

In order for parametric models to have any validity they must be based on or proven using actual project data.

为了参数的模型具备有效性，他们就必须基于或者被证明为是使用精确的项目数据的。

So, we have mostly focused on the use of parametric equations just for one dimensional objects, lines, and curves.

我们主要还是关注，参数方程的运用，主要是一维的，比如直线、曲线等。

So, now, just to show you that we can do a lot of things when we have a parametric equation, here is a small mystery.

现在我们可以做很多事情了，因为我们有了参数方程，现在有一件神秘的事。

Your target repository may or may not support full-text (native content) search, parametric (property-based) search, or both.

目标存储库可能支持，也可能不支持全文(原始内容)搜索或参数(基于属性的)搜索。

So, I will have some parametric curve that lives on this surface so, the question is, what's going to happen at any given time?

也就是我在此平面上有一个参数曲线，所以问题就是，在任意给定时刻会发生什么呢？

Even if you have parametric estimation models, the early prototyping effort will help you to validate the parametric estimates.

即使您拥有了参数评估模型，早期的原型成果同样可以帮助您验证这个参数评估。

One thing developers usually ponder when starting a new project is the strategy they need to employ to write good parametric code.

当启动一个新项目时，开发者通常深思的一个问题是他们需要采用用来编写具有良好参数的代码的策略。

Parametric methods are very useful for subjecting uncertain situations to the rigors of a pre-defined and proven mathematical model.

参数化的方法对于将不确定的情况置于一个预定义的和被证明是精确的模型之下十分有用。
