展开的表达式可以被用来初始化一个对象，可以初始化从std::atomicvalue。如果原子对象具有静态存储持续时间，这个初始化是常数初始化.
Original:
Expands the an expression which can be used to initialize an std::atomic object that can be initialized from value. If the atomic object has static storage duration, this initialization is 常数初始化.

[编辑] 注释

从另一个线程访问的变量在初始化过程中，即使是通过一个原子操作，是数据争用（它可能发生，如果该地址被立即传递给std::memory_order_relaxed操作与另一个线程）
Original:
Accessing the variable during initialization from another thread, even through an atomic operation, is a data race (it may happen if the address is immediately passed to another thread with a std::memory_order_relaxed operation)

这个宏主要是为了与C兼容，它的行为一样的构造函数std::atomic的
Original:
This macro is primarily provided for compatibility with C; it behaves the same as the constructor of std::atomic.
