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(gè)對象到容器中通常會(huì )導致容器中的新元素從被插入對象中復制分配器。
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(gè)會(huì )被其它線(xiàn)程修改的容器插入對象是沒(méi)有線(xiàn)程安全性保證的，雖然在多數平臺上，它是無(wú)鎖定線(xiàn)程安全的。
