	_T_	_T_
	_Hash_	_Hash_
	A unary function object type that acts a hash function for a `Key`. It takes a single argument of type `Key` and returns a value of type `std::size_t`.	一个一元函数对象类型，用作 `Key` 的哈希函数。它接受一个 `Key` 类型的参数并返回 `std::size_t` 类型的值。
	_Pred_	_Pred_
	A binary function object that induces an equivalence relation on values of type `Key`. It takes two arguments of type `Key` and returns a value of type `bool`.	一个二元函数对象，在 `Key` 类型的值上诱导出等价关系。它接受两个 `Key` 类型的参数并返回 `bool` 类型的值。
	_Allocator_	_Allocator_
	An allocator whose value type is the same as the container's value type.	一个分配器，其值类型与容器的值类型相同。
	Allocators using https://en.cppreference.com/w/cpp/named_req/Allocator#Fancy_pointers[fancy pointers] are supported.	支持使用 https://en.cppreference.com/w/cpp/named_req/Allocator#Fancy_pointers[花式指针^] 的分配器。
	The elements of the container are held into an internal _bucket array_. An element is inserted into a bucket determined by its hash code, but if the bucket is already occupied (a _collision_), an available one in the vicinity of the original position is used.	容器的元素存储在内部的__桶数组__中。元素根据其哈希码被插入到对应的桶中，但如果该桶已被占用（即发生__冲突__），则会使用原始位置附近可用的桶。
	The size of the bucket array can be automatically increased by a call to `insert`/`emplace`, or as a result of calling `rehash`/`reserve`. The _load factor_ of the container (number of elements divided by number of buckets) is never greater than `max_load_factor()`, except possibly for small sizes where the implementation may decide to allow for higher loads.	桶数组的大小可通过调用 `insert` / `emplace` 自动增加，也可通过调用 `rehash` / `reserve` 来调整。容器的__负载因子__（元素数量与桶数量的比值）始终不会超过 `max++_++load++_++factor()` ，但在小规模数据情况下，实现可能允许更高的负载因子。
	If `link:../../../../../container_hash/doc/html/hash.html#ref_hash_is_avalanchinghash[hash_is_avalanching]<Hash>::value` is `true`, the hash function is used as-is; otherwise, a bit-mixing post-processing stage is added to increase the quality of hashing at the expense of extra computational cost.	若 link:../../../../../container_hash/doc/html/hash.html#ref_hash_is_avalanchinghash[`hash++_++is++_++avalanching`]`++<++Hash++>++::value` 为 `true` ，则直接使用哈希函数；否则，会添加一个位混合后处理阶段以提高哈希质量，但会牺牲额外的计算成本。

	Configuration Macros	配置宏
	`BOOST_UNORDERED_ENABLE_STATS`	`BOOST++_++UNORDERED++_++ENABLE++_++STATS`
	Globally define this macro to enable xref:reference/stats.adoc#stats[statistics calculation] for the container. Note that this option decreases the overall performance of many operations.	全局定义此宏，以启用容器的 xref:reference/stats.adoc#stats[统计计算] 功能。请注意，此选项会降低许多操作的总体性能。

	Typedefs	类型定义
	An iterator whose value type is `value_type`.	一种迭代器，其值类型为 `value++_++type` 。
:344	The iterator category is at least a forward iterator.	迭代器类别至少为前向迭代器。
	Convertible to `const_iterator`.	可转换为 `const++_++iterator` 。

	A constant iterator whose value type is `value_type`.	一个常量迭代器，其值类型为 `value++_++type` 。
:357	The iterator category is at least a forward iterator.	迭代器类别至少为前向迭代器。
	Constructors	构造函数
	Default Constructor	默认构造函数
	```c++ unordered_flat_map(); ```	```c++ unordered_flat_map(); ```
	Constructs an empty container using `hasher()` as the hash function, `key_equal()` as the key equality predicate and `allocator_type()` as the allocator.	构造一个空容器，使用 `hasher()` 作为哈希函数、 `key++_++equal()` 作为键相等性谓词、以及 `allocator++_++type()` 作为分配器。
:370	Postconditions:;; `size() == 0` Requires:;; If the defaults are used, `hasher`, `key_equal` and `allocator_type` need to be https://en.cppreference.com/w/cpp/named_req/DefaultConstructible[DefaultConstructible^].	后置条件：`size() == 0` 要求：若使用默认参数，则 `hasher`、`key_equal` 和 `allocator_type` 需满足 https://en.cppreference.com/w/cpp/named_req/DefaultConstructible[可默认构造^] 要求。

	Bucket Count Constructor	桶数构造函数
	```c++ explicit unordered_flat_map(size_type n, const hasher& hf = hasher(), const key_equal& eql = key_equal(), const allocator_type& a = allocator_type()); ```	```c++ explicit unordered_flat_map(size_type n, const hasher& hf = hasher(), const key_equal& eql = key_equal(), const allocator_type& a = allocator_type()); ```

Key	English	Chinese (Simplified Han script)
:1371	Invalidates iterators, pointers and references, and changes the order of elements.	使迭代器、指针和引用失效，并改变元素的顺序。
:1374	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：若抛出异常（除非由容器的哈希函数或比较函数抛出），则该函数无效果。

:1459	Notes:;; Behavior is undefined if the two containers don't have equivalent equality predicates.	注意：如果两个容器的相等谓词不等价，则行为未定义。
:1461	---	---
:1473	Notes:;; Behavior is undefined if the two containers don't have equivalent equality predicates.	注意：如果两个容器的相等谓词不等价，则行为未定义。
:1485	If `Allocator::propagate_on_container_swap` is declared and `Allocator::propagate_on_container_swap::value` is `true` then the containers' allocators are swapped. 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。
