postscript产生了Dojo小部件生命周期方法，但对标准dojo类没有什么用处。
Postscript drives the Dojo widget life cycle methods, but provides no benefit to a standard Dojo class.
如果，在小部件生命周期内一些连接已经不再需要，那么实现者就可以通过调用disconnect方法来手动断开这些连接以减少事件的处理。
If, during the widget lifecycle, some connections are not needed any longer, the implementer can manually disconnect them by calling the disconnect method to reduce the event handling.
实现者负责管理小部件的整个生命周期，包括小部件的销毁。
Implementers are in charge of managing the whole widget lifecycle, including the widget destruction.
请注意，虽然 SO系统与其所属的SO解决方案具有相同的生命周期，但面向服务的部件具有自己的生命周期。
Note that whereas an SO system part shares the same lifecycle as the SO solution that it is a part of, a service-oriented part has a lifecycle of its own.
