Every time a pointer reference is modified , such as through an assignment statement , or when a reference goes out of scope , the compiler must generate code to update the referenced object s reference count 每次修改指針引用時(比如通過賦值語句) ,或者當(dāng)引用超出范圍時,編譯器必須生成代碼以更新引用的對象的引用計數(shù)。
An assignment statement evaluates the expression list ( remember that this can be a single expression or a comma - separated list , the latter yielding a tuple ) and assigns the single resulting object to each of the target lists , from left to right 一個賦值語句對表達(dá)式序列求值(還記得這可以是單個表達(dá)式或者一個逗號分隔的序列,后者導(dǎo)出一個元組) ,然后從左到右地將對象結(jié)果一一地賦給目的序列的每個對象。
An augmented assignment evaluates the target ( which , unlike normal assignment statements , cannot be an unpacking ) and the expression list , performs the binary operation specific to the type of assignment on the two operands , and assigns the result to the original target 一條增量賦值語句對目標(biāo)(和一般的賦值語句不同,它不能是展開的對象)和表達(dá)式列表求值,執(zhí)行特定于兩個操作數(shù)的賦值類型的二元運(yùn)算,并將結(jié)果賦值給原先的目標(biāo)。
Abstract : the objective of this paper was to develop a semiautomatic method for the translation of assignment statements into their corresponding gscct expressions , and thus to facilitate automatic creation of database of generic chemical structures in patents 文摘:本文研究了自然語言處理技術(shù)在藥物專利檢索中的應(yīng)用,開發(fā)出一套翻譯軟件,能夠?qū)⑺幬飳@袑ψ逍宰兞康奈谋久枋霭胱詣踊剞D(zhuǎn)化為符合規(guī)則的gscct格式,為準(zhǔn)確、高效地建立藥物專利檢索數(shù)據(jù)庫打下了基礎(chǔ)
