双语例句
- First notice that this subexpression is itself composed of two child subexpressions, with some stuff in the middle that is not part of any child subexpression.
首先，请注意这个子表达式本身由两个子表达式组成，两者之间的字符并不属于任何一方。 - NOT& Matches documents where the first subexpression
NOT&匹配那些第一个子表达式匹配的文档 - Finally, we get the second child subexpression, which other than the "don't refer" operator consists of some stuff in square brackets, and a plus sign.
最后，我们看到第二个子表达式，它除了有由方括号组成的“不引用”运算符外，还有一个加号。 - The process of evaluation is similar to calculating by hand: while the expression contains parentheses, the subexpression inside the deepest nested pair of parentheses is evaluated.
求值过程类似于手工计算：如果表达式中包含括号，先求嵌套最深的括号对中的子表达式的值。 - More often it simply has the effect of removing a common subexpression.
通常它只是除去公共子表达式。 - One such trick is the?: operator at the beginning of a subexpression.
其中一个技巧是子表达式开始处的？：运算符。 - Common Subexpression Elimination and Algebraic Simplification
公共子表达式消除和代数简化 - Matches the preceding character or subexpression one or more times.
一次或多次匹配前面的字符或子表达式。 - Represents the results from a single subexpression capture.
表示单个子表达式捕获中的结果。 - Constant folding, common subexpression elimination are effective techniques in optimizing intermediate code.
常量合并、删除公共子表达式是中间代码优化时采用的有效技术。 - This DCT/ IDCT architecture distributes the multiply/ accumulate with fixed coefficients into additions for partial products at first, then decreases the number of additions by sharing subexpression, and accumulates all partial products to get the transform result based on optimized Wallace trees at last.
该体系结构首先将DCT／IDCT中的常系数乘加运算分散为部分积加法运算，然后通过共享公共子表达式减少加法数量，最后用优化的Wallace树汇总部分积以计算最终结果。 - Using cyclic convolution is helpful in exploiting the word-level data sharing in computing different DCT/ IDCT outputs. Adopting the common subexpression sharing is beneficial to the bit-level data sharing in computing the outputs.
使用循环卷积方法在计算得到不同的DCT/IDCT输出过程中有利于挖掘字级的数据共享，而使用公共子表达式共享技术则有利于比特级的数据共享。
