gcv是一個(gè)縮略詞，意思是總熱值，我們先來看到這個(gè)單詞的讀音，這個(gè)單詞是一個(gè)縮略詞，我們直接讀字母音GCV，這個(gè)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(rèn)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(gè)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(nèi)實(shí)驗(yàn)表明GCV能明顯抑制轉(zhuǎn)染細(xì)胞接種的腫瘤，而親代細(xì)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(diào)整參數(shù)的新方法，同時(shí)，給出了一個(gè)數(shù)學(xué)例子，并與廣義交叉實(shí)驗(yàn)B—樣條函數(shù)仿真比較驗(yàn)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(cè)量出來，在上面這三個(gè)句子中，GCV都指的是總熱量，gcv這個(gè)單詞你學(xué)會(huì)了嗎？
