	bucket_count	bucket_count

	Returns:;; The size of the bucket array.	返回：桶数组的大小。

	Hash Policy	哈希策略
	load_factor	负载因子
	```c++ float load_factor() const noexcept; ```	```c++ float load_factor() const noexcept; ```
	Returns:;; `static_cast<float>(size())/static_cast<float>(bucket_count())`, or `0` if `bucket_count() == 0`.	返回：`static_cast<float>(size())/static_cast<float>(bucket_count())`，如果 `bucket_count() == 0` 则返回 `0`。</float></float>

	max_load_factor	max_load_factor
	```c++ float max_load_factor() const noexcept; ```	```c++ float max_load_factor() const noexcept; ```
	Returns:;; Returns the container's maximum load factor.	返回：容器的最大负载因子。

	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:;; Does nothing, as the user is not allowed to change this parameter. Kept for compatibility with `boost::unordered_map`.	效果：不执行任何操作，因为用户不允许更改此参数。保留此函数是为了与 `boost::unordered_map` 保持兼容。
:1434	---	---
	max_load	max_load
	```c++ size_type max_load() const noexcept; ```	```c++ size_type max_load() const noexcept; ```
	Returns:;; The maximum number of elements the container can hold without rehashing, assuming that no further elements will be erased. Note:;; After construction, rehash or clearance, the container's maximum load is at least `max_load_factor() * bucket_count()`. This number may decrease on erasure under high-load conditions.	返回：容器在不触发重哈希的情况下能够容纳的最大元素数量（假设不再有元素被擦除）。注意：在构造、重哈希或清空操作之后，容器的最大负载至少为 `max_load_factor() * bucket_count()`。在高负载条件下，该数值可能会因元素擦除而减小。
:1448	---	---
	rehash	重哈希
	```c++ void rehash(size_type n); ```	```c++ void rehash(size_type n); ```
	Changes if necessary the size of the bucket array 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.	必要时更改桶数组的大小，使其至少包含 `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关联的 `bucket_count()`。
	When `size() == 0`, `rehash(0)` will deallocate the underlying buckets array. If the provided Allocator uses fancy pointers, a default allocation is subsequently performed.	当 `size() == 0` 时，`rehash(0)` 将释放底层的桶数组。如果提供的分配器使用异形指针，则会随后执行一次默认分配。
:1459	Invalidates iterators and changes the order of elements.	使迭代器失效并改变元素的顺序。
:1462	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的），则该函数无效果。
:1464	---	---
	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()))`.	等价于 `a.rehash(ceil(n / a.max_load_factor()))`。
