This Paper discusses the impact of export trade on China's economic growth by analyzing a stationary real variable system and a non-stationary nominal variable system separately.
这是因为实际的源代码和变量绑定可以更改，这是建立在环境或者构建宏预处理程序指令的时间定义的基础上的。
This is because the actual source code and the variable binding can change, based on the environment or the build time definitions of macros and preprocessor commands.

在这种情况下，您可以向该变量分配一个实际的类名称，有效地为原先的类创建一个别名(参见清单3)。
In this case, you assign the actual class name to the variable, effectively creating an alias to the original class (see Listing 3).

实际的类型参数可以由泛型类定义的类型变量匹配。
The actual type arguments can be matched to the type variables defined by the generified class.
编目中保存的是全局变量的定义而非实际的值，了解这一点非常重要。
It is important to understand that only the definition of the global variable is stored in the catalogs and not the actual values.
不幸的是，没有实际的方式来比较每一变量的影响，因此没有实际的方式评价净影响。
Unfortunately there is no real way of comparing the impact of each variable, and so there is no real way of judging the net effect.
对于占用资源很多的sql语句，查看实际的变量值(字符)而不是参数标记也许对优化器较为有益。
For very expensive SQL statements, the optimizer may benefit from seeing actual variable values (literals) instead of parameter markers.
绑定标量变量以及在此问题上的任何绑定变量都需要将其实际数据存储在某个地方。
Note that a tied scalar variable, and any tied variable for that matter, needs to store its actual data somewhere.
这看起来很方便，实际上它与向CLASSPATH环境变量添加目录一样，存在长远的潜在问题。
While this seems convenient, it is also a long-term mistake akin to adding directories to the CLASSPATH environment variable.
如果这个元素的名字是title，这段代码将把该元素的实际内容放到字符串变量title中。
If the name is title, the code puts the actual contents of the element into the String variable title.
它需要整数参数errno，该参数应该是全局errno变量的实际数值。
It requires an integer argument, errno, which should be the actual value of the global errno variable.
门户框架常常为Portlet内容指定变量，以在实际Portlet输出上显示动态Portlet标题。
Portal frameworks often specify variables for portlet content to display dynamic portlet titles above the actual portlet output.
应该在定义有问题的实际全局(静态全局)变量之前定义ExceptionHandler的全局(静态全局)实例。
A global (static global) instance of ExceptionHandler should be defined prior to the definition of the actual global (static global) variable in question.
为了处理变量名和实际值，Bison的语义类型必须进行增强
To handle variable names and real values, the semantic type of Bison has to be enhanced
当从脚本中调用AdminTask命令时，用户通常更期望(和实际需要)为命令参数指定变量而不是文本。
When invoked from within a script, it is usually more desirable (and practical) to specify variables rather than literals.
现在，让我们看一下如何实际使用环境变量。
Now, let's take a look at how one actually USES environment variables. Here's an example.
这个变量实际上是一个xml树，以后可将其他模板应用于该树。
This variable is actually an XML tree to which I can then apply other templates.
这并非只是简单的文本搜索，它实际上会提取出变量名和常量名，然后根据语法树进行比较。
This is not a textual search, it actually strips out variable names and constants and performs comparisons against the syntax tree.
