gcv是一個縮略詞，意思是總熱值，我們先來看到這個單詞的讀音，這個單詞是一個縮略詞，我們直接讀字母音GCV，這個縮略詞的全稱是generalized cross-validation，Generalized的意思是總的，Cross是交叉的意思，Validation生效、確認的意思，合在一起的話gcv就是作為總熱值的意思來使用；

例如在下面這三個句子里，In vivo, growth of tumors which formed by transfected，cells was significantly inhibited by GCV，however, there was no similar inhibitive effect found，in control group，體內實驗表明GCV能明顯抑制轉染細胞接種的腫瘤，而親代細胞接種的腫瘤未受抑制，So, a novel method for choosing the regularization，data was presented，One numerical example was given with the comparison，of generalized cross-validation (GCV) B-splines，提出了一種選擇調整參數的新方法，同時，給出了一個數學例子，并與廣義交叉實驗B—樣條函數仿真比較驗證，The GCV of this kind of liquid can not be measured by this tool，這種液體的總熱量沒辦法被這種工具測量出來，在上面這三個句子中，GCV都指的是總熱量，gcv這個單詞你學會了嗎？
