Parametric Estimating: basically this is scaling an estimate.(參數估計：基本上，這是按比例擴縮的估計方法。)

Let us take a look at our simple doIt example with a bit of parametric typing thrown in (in Listing 3).(下面我們來看一個簡單的doIt例子，它使用了一些參數類型化(見清單3)。)

During a typical year the 90 or 100 most critical SSA projects are estimated using SEER parametric modeling solutions.(在一個典型的年份期間，90或者100個最關鍵的SSA項目是使用SEER參數建模解決方案被評估的。)

OK, so if not, let's move on to linear parametric equations.(如果沒有的話，我們繼續往下，線性參數方程組。)

Parametric methods are very useful for subjecting uncertain situations to the rigors of a pre-defined and proven mathematical model.(參數化的方法對于將不確定的情況置于一個預定義的和被證明是精確的模型之下十分有用。)

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.(現在我們可以做很多事情了，因為我們有了參數方程，現在有一件神秘的事。)

Parametric/predictive software modeling(參數的/預言性的軟件建模)

Based on the "XMLAttributeDefinition" in the model file in Figure 5, parametric search on the values of element "price" is possible.(根據圖5的模型文件中的“XMLAttributeDefinition”，可以對“price”元素的值進行參數化搜索。)

OK, so we are going to learn about parametric equations of lines.(我們馬上就要學習直線的參數方程。)

In fact, parametric equations of lines always look like that.(實際上，直線的參數方程總是這個樣子的。)
