与大多数现代编程语言一样，需要使用AND和OR语句对表达式或它们的值进行条件运算。
Like in most modern programming languages, the and and or statements are necessary for definitive conditional evaluations of expressions or their values.
与属性相似，度量是组成事实对象的表上的列或列表达式。
Measures, like attributes, are columns or column expressions on the tables that make up a facts object.
与在单个dbspace中保存多个表或索引片段提高了查询性能，这样做胜过将每个分段表达式存储在不同的dbspace中。
Storing multiple table or index fragments in a single dbspace improves query performance over storing each fragmented expression in a different dbspace.
IDN或其子树可以出现在xsl:apply-templates的select表达式中，允许按照与XML输入文档相同的方式处理。
The IDN, or a sub-tree of it, can be in the select expression of xsl:apply-templates, allowing the tree to be processed in the same manner as an XML input document.
1(或\ \2)表示模式与匹配表达式的第一个(或第二个)子表达式相匹配。
1 (or \ \ 2) means the pattern matched by the first (or second) subexpression of the match expression.
这些语句也规定程序员可以选择的变量与参数种类，以及当一个表达式使用过程或函数时代码将返回的值的类型。
These statements also define the kinds of variables and parameters the programmer can choose and the type of value that the code will return when an expression accesses the procedure or function.
本文提出一种新的算法，它是从开关函数最小项集合所对应的整数集出发，通过对整数进行算术运算，从而求得接近最小的两级与一或表达式。
An algorithm for such purpose, quite different from any others so far known, is here presented on the basis of arithmetic operations on integers, which correspond to the minterms of the function.
您可以将字符串表达式中的每个字符与具体字符、通配符、字符列表或字符范围进行匹配。
You can match each character in the string expression against a specific character, a wildcard character, a character list, or a character range.
索引或表达式与集合的现有成员不匹配。
Index or expression does not match an existing member of the collection.
由于一个语句可以包含一个或多个表达式，因此语句与表达式是有区别的。
A statement differs from an expression in that a statement can consist of one or more expressions.
本文中我们在经典风险模型的基础上构造了三类随机变量具有相依性的风险模型并对它们进行了研究，得到了与破产相关的一些变量的表达式或性质。
In this text, based on the classical risk model, we construct and research three kinds of new risk models with dependence. Finally we obtain some expressions or characters of the variables about ruin.
正在调用重载方法或属性的表达式找不到与传递的参数类型完全匹配的参数。
An expression that is calling an overloaded method or property does not find an exact match to the types of arguments that are passed.
按位或向结果表达式添加位，而按位与只选择两个运算符之间相同的位。
Bitwise-or adds bits to the resulting expression, whereas bitwise-and selects only those bits in common between its two operators.
本文中，我们以经典风险模型为基础构造了三类风险模型并且对其进行研究，得到了与破产相关的一些变量的表达式或性质。
In this text, based on the classical risk model, we construct and research three kinds of new risk models. Finally we obtain some expressions or characters of the variables about ruin.
并分析了产生这种差异的原因，主要是经典强度准则表达式中采用的无拉剪耦合假设和层与层之间理想粘接假设，只适用于单层板或正交各向异性板。
The main reason came from the assumptions of non-tension-shear coupling whose is correct only for lamina and orthotropic laminates, and realistic bond between layers.
