	```c++ float load_factor() const noexcept; ```	```c++ float load_factor() const noexcept; ```
	Returns:;; The average number of elements per bucket.	返回：;; 每个桶的平均元素个数。
:1600	---	---
	max_load_factor	max_load_factor
	```c++ float max_load_factor() const noexcept; ```	```c++ float max_load_factor() const noexcept; ```
	Returns:;; Returns the current maximum load factor.	返回：;; 返回当前的最大负载因子。
:1611	---	---
	Set max_load_factor	设置最大负载因子
	```c++ void max_load_factor(float z); ```	```c++ void max_load_factor(float z); ```
	Effects:;; Changes the container's maximum load factor, using `z` as a hint.	效果：;; 改变容器的最大负载因子，以 `z` 作为提示。
:1621	---	---
	rehash	重哈希
	```c++ void rehash(size_type n); ```	```c++ void rehash(size_type n); ```
	Changes the number of buckets so that there are at least `n` buckets, and so that the load factor is less than or equal to the maximum load factor. When applicable, this will either grow or shrink the `bucket_count()` associated with the container.	改变桶的数量，使得至少包含 `n` 个桶，并且使得负载因子小于或等于最大负载因子。在适用的情况下，这将增大或缩小与容器相关联的 `bucket_count()`。
	When `size() == 0`, `rehash(0)` will deallocate the underlying buckets array.	当 `size() == 0` 时，`rehash(0)` 将释放底层桶数组的内存。
:1633	Invalidates iterators, and changes the order of elements. Pointers and references to elements are not invalidated.	使迭代器失效，并改变元素的顺序。指向元素的指针和引用不会失效。
:1636	Throws:;; The function has no effect if an exception is thrown, unless it is thrown by the container's hash function or comparison function.	抛出：;; 如果抛出异常（除非是由容器的哈希函数或比较函数抛出），则该函数无效。
:1638	---	---
	reserve	保留
	```c++ void reserve(size_type n); ```	```c++ void reserve(size_type n); ```
	Equivalent to `a.rehash(ceil(n / a.max_load_factor()))`, or `a.rehash(1)` if `n > 0` and `a.max_load_factor() == std::numeric_limits<float>::infinity()`.	等价于 `a.rehash(ceil(n / a.max_load_factor()))`；如果 `n > 0` 且 `a.max_load_factor() == std::numeric_limits<float>::infinity()`，则等价于 `a.rehash(1)`。</float>
	Similar to `rehash`, this function can be used to grow or shrink the number of buckets in the container.	与 `rehash` 类似，此函数可用于增加或减少容器中桶的数量。
:1649	Invalidates iterators, and changes the order of elements. Pointers and references to elements are not invalidated.	使迭代器失效，并改变元素的顺序。指向元素的指针和引用不会失效。
:1652	Throws:;; The function has no effect if an exception is thrown, unless it is thrown by the container's hash function or comparison function.	抛出：;; 如果抛出异常（除非是由容器的哈希函数或比较函数抛出），则该函数无效。
	Deduction Guides	推导指引
	A deduction guide will not participate in overload resolution if any of the following are true:	在以下任一条件成立时，推导指引将不参与重载决议：
	- It has an `InputIterator` template parameter and a type that does not qualify as an input iterator is deduced for that parameter. - It has an `Allocator` template parameter and a type that does not qualify as an allocator is deduced for that parameter. - It has a `Hash` template parameter and an integral type or a type that qualifies as an allocator is deduced for that parameter. - It has a `Pred` template parameter and a type that qualifies as an allocator is deduced for that parameter.	- 它具有 `InputIterator` 模板参数，并且为该参数推导出的类型不符合输入迭代器的要求。 - 它具有 `Allocator` 模板参数，并且为该参数推导出的类型不符合分配器的要求。 - 它具有 `Hash` 模板参数，并且为该参数推导出的是整数类型或符合分配器要求的类型。 - 它具有 `Pred` 模板参数，并且为该参数推导出的是符合分配器要求的类型。
	A `size_type` parameter type in a deduction guide refers to the `size_type` member type of the container type deduced by the deduction guide. Its default value coincides with the default value of the constructor selected.	推导指引中的 `size_type` 参数类型指向由该推导指引所推导出的容器类型的 `size_type` 成员类型。其默认值与所选构造函数的默认值一致。
	__iter-value-type__	_iter-value-type_
	__iter-key-type__	__iter-key-type__
	__iter-mapped-type__	__iter-mapped-type__

Otherwise, swapping with unequal allocators results in undefined behavior.	如果 `Allocator::propagate_on_container_swap` 已声明且 `Allocator::propagate_on_container_swap::value` 为 `true`，则交换两个容器的分配器。否则，使用不相等的分配器进行交换将导致未定义行为。
