查询词典 extern

If an initializer is present, the declaration is treated as a definition even if the declaration is labeled extern

如果声明有初始化式，那么它可被当作是定义，即使声明标记为 extern

If the definition of the external variable occurs in the source file before its use in a particular function, then there is no need for an extern declaration in the function.

在源文件中，如果外部变量的定义出现在使用它的函数之前，那么在那个函数中就没有必要使用extern声明。

If you specify both inline and extern in the function definition, then the definition is used only for inlining. In no case is the function compiled on its own, not even if you refer to its address explicitly.

当一个函数是inline和extern的，这个函数定义只会在调用中展开，而不会被编译，即使你明确引用它的地址。

According to Newton's first law of motion a body is in motion but actually never is there a body which remain in motion forever because it is impossible to get rid of extern al influence.

Linkage is done by placing the keyword extern prior to a variable declaration.

链接是通过把关键字放在一个外部的变量声明中。

To declare what we can do with a set, we start a header file Set.h:#ifndef SET_H #define SET_H extern const void * Set; void * add (void * set, const void * element); void * find (const void * set, const void * element); void * drop (void * set, const void * element); int contains (const void * set, const void * element);#endif The preprocessor statements protect the declarations: no matter how many times we include Set.h, the C compiler only sees the declarations once.

宣布我们能做些什么用一套，我们开始一个头文件Set.h ：＃ ifndef SET_H ＃定义SET_H 外部构造无效*设置；无效*地址（无效*一套，无效*常量元素）；无效*找到（常量无效*一套，无效*常量元素）；无效*下降（无效*一套，无效*常量元素）；国际载（常量无效*一套，无效*常量元素）；＃ endif 预报表保护声明：无论多少次我们包括Set.h ， C编译器将只看到申报一次。

Include #include #include #include using namespace std;//下面的几句来自其它的头文件 char* itoa(int value, char* workArea, int radix ); extern int fileIdCounter

全局变量的出现应该早已引起了我们的警觉，使我们特别留意那些企图在它被初始化之前就使用它的代码。

The effect of Selenium on the content of intern or extern polysaccharide and protein of Armillaria mellea was studied, through culturing in medium with different selenium concentrations.

Methods We electronically searched The Cochrane Library (Issue 4, 2009), PubMed (1980 to 2009), Ovid MEDLINE (1950 to 2009), Ovid EBM Database (1991 to 2009), EMbase (1980 to 2009), CBM (1978 to 2009) and CNKI (1979 to 2009) to collect literature about intravertebral analgesia for extern al cephalic version. We screened randomized cont rolled trials according to the predefined inclusion and exclusion criteria, extracted data and evaluated the quality of the included studies, and then performed meta-analyses by using RevMan 5.0.13 software.

计算机检索Cochrane Library （2009年第4期）、PubMed (1980~2009)、Ovid MEDLINE (1950~2009)、Ovid循证医学数据库(1991~2009)、EMbase (1980~2009)、CBM (1978~2009)和CNKI (1979~2009)，按纳入和排除标准筛选椎管内镇痛在外倒转胎位术中应用的随机对照试验，提取资料及评价文献质量后，采用RevMan5.0.13软件对数据进行Meta分析。

Methods:Using dogs as experimental objects,we ligated one side of carotis extern al artery and occipitalis artery.Electromagnetic flowmeter was used to measure t he blood flowing volume of carotis artery;polygraph system was used to investigate the change of blood pressure,ECG and heart rate.

以犬为实验对象，结扎一侧颈外动脉及枕动脉，以电磁流量计测颈动脉血流量，用多道生理记录仪记录血压、心电图及心率的变化。
