:703	Inserts an object, constructed with the arguments `args`, in the container if and only if there is no element in the container with an equivalent key.	当且仅当容器中不存在具有等价键的元素时，才插入一个使用参数 `args` 构造的对象。
:706	Requires:;; `value_type` is constructible from `args`. Returns:;; The `bool` component of the return type is `true` if an insert took place. + + If an insert took place, then the iterator points to the newly inserted element. Otherwise, it points to the element with equivalent key. Throws:;; If an exception is thrown by an operation other than a call to `hasher` the function has no effect. Notes:;; Can invalidate iterators, pointers and references, but only if the insert causes the load to be greater than the maximum load. +	要求：;; `value_type` 可以从 `args` 构造。返回：;; 如果进行了插入，则返回类型的 `bool` 分量为 `true`。如果进行了插入，则迭代器指向新插入的元素；否则，指向具有等价键的元素。抛出：;; 如果除调用 `hasher` 之外的操作抛出异常，则该函数无效。备注：;; 可能会使迭代器、指针和引用失效，但仅当插入导致负载因子大于最大负载因子时才会发生。
