	English Returns:;; A `node_type` owning the element if found, otherwise an empty `node_type`. Throws:;; Only throws an exception if it is thrown by `hasher` or `key_equal`. Notes:;; In C++17 a node extracted using this method can be inserted into a compatible `unordered_multiset`, but that is not supported yet. + + The `template<class K>` overload only participates in overload resolution if `Hash::is_transparent` and `Pred::is_transparent` are valid member typedefs and neither `iterator` nor `const_iterator` are implicitly convertible from `K`. The library assumes that `Hash` is callable with both `K` and `Key` and that `Pred` is transparent. This enables heterogeneous lookup which avoids the cost of instantiating an instance of the `Key` type.
	Chinese (Simplified Han script) ↹ ↵ NBS … 「 」 『 』 ﹙-﹚ ‐ – — 返回：若找到元素，则返回拥有该元素的 `node_type`；否则返回空 `node_type`。抛出：仅当 `hasher` 或 `key_equal` 抛出异常时才会抛出异常。说明：在 C++17 中，通过此方法提取的节点可以插入到兼容的 `unordered_multiset` 中，但该功能尚未支持。+ +`template<class k="">` 重载仅在以下条件下参与重载决议：`Hash::is_transparent` 和 `Pred::is_transparent` 是有效的成员 typedef，且 `iterator` 和 `const_iterator` 均不能从 `K` 隐式转换。库假定 `Hash` 可同时以 `K` 和 `Key` 调用，且 `Pred` 是透明的。这实现了异构查找，从而避免了实例化 `Key` 类型对象的开销。</class> 390/7460 · 746 Needs editing
