Parametric Estimating: basically this is scaling an estimate.(參數(shù)估計：基本上，這是按比例擴(kuò)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(shù)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(guān)鍵的SSA項目是使用SEER參數(shù)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(xù)往下，線性參數(shù)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(shù)化的方法對于將不確定的情況置于一個預(yù)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(xiàn)在我們可以做很多事情了，因為我們有了參數(shù)方程，現(xiàn)在有一件神秘的事。)

Parametric/predictive software modeling(參數(shù)的/預(yù)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(jù)圖5的模型文件中的“XMLAttributeDefinition”，可以對“price”元素的值進(jìn)行參數(shù)化搜索。)

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

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