注釋

6-10)

構造函數，具有第一std::allocator_arg_t類型的參數，必須有一個第二個參數是alloc類型AAllocator。該分配器是用於創建function可以使用任何內部數據結構的內存.

Original:

Constructors that have a first parameter of type std::allocator_arg_t must have a second argument alloc of type A that is an Allocator. This allocator is used to create memory for any internal data structures that the function might use.

5，10）的類型F應該CopyConstructible，和對象f應該Callable。函數創建的對象將是空的，如果f是一個空函數指針，NULL指針成員，或者如果f是一個std::function!f == true。被移動到函數對象的參數f.

Original:

5, 10) The type F should be CopyConstructible and the object f should be Callable. The resulting function object that is created will be empty if f is a NULL function pointer, a NULL pointer to member, or if f is a std::function and !f == true. The argument f is moved into the resulting function object.
