  • '“静态”的存储时间。变量在程序开始时分配和释放程序结束时。只有一个实例存在的变量。所有的全局变量有这样的存储时间，再加上​​那些声明的static或extern.
    Original:
    static storage duration. The variable is allocated when the program begins and deallocated when the program ends. Only one instance of the variable exists. All global variables have this storage duration, plus those declared with static or extern.

  • “”线“”的存储时间（C++11 起）。变量线程开始时分配和释放的线程结束时。每个线程都有它自己的实例的变量。只有声明的变量thread_local有这样的存储时间。 thread_local只能被声明为全局变量，再加上，那些与static声明或extern.
    Original:
    thread storage duration （C++11 起）. The variable is allocated when the thread begins and deallocated when the thread ends. Each thread has its own instance of the variable. Only variables declared thread_local have this storage duration. thread_local can only be declared for global variables, plus those declared with static or extern.

[编辑] 联动

连接是指一个变量或函数被称为在其他范围内的能力。如果具有相同标识符的变量或函数的声明在几个范围，但不能被称为从所有这些，那么所产生的几个实例变量。以下联系确认
Original:
Linkage refers to the ability of a variable or function to be referred to in other scopes. If a variable or function with the same identifier is declared in several scopes, but cannot be referred to from all of them, then several instances of the variable are generated. The following linkages are recognized:
