insert object的用法和樣例：
例句
- With this model, inserting an object into a container usually causes the new container item to copy the allocator from the object that was inserted.
使用此模型，插入一個對象到容器中通常會導致容器中的新元素從被插入對象中複製分配器。 - Inserting an object in containers that will be modified by different threads has no thread safety guarantee, although in most platforms it will be thread-safe without locking.
向一個會被其它線程修改的容器插入對象是沒有線程安全性保證的，雖然在多數平台上，它是無鎖定線程安全的。
