1·We will create the enclosing frame at the end of the program.
我们将在程序的最后创建这个封闭的框架。
2·A scope activity can contain more scope activities within it, so activities within a scope can also access variables of all enclosing scopes.
范围活动可以在其内部包含多个范围，因此范围中的活动也可以访问所有封闭范围的变量。
3·The activity is then put in state failed and the fault is propagated to the fault handler of the next enclosing scope.
然后将该活动置于已失败状态，并且将错误传播到下一个封闭范围的错误处理程序。
4·In both cases the source and the target activity both have to be directly nested in the same enclosing construct.
在这两种情况中，源活动和目标活动都必须直接嵌入同一封闭结构中。
5·Note that scope administrators are passed on by scopes to their enclosed scopes, that is, scope administrators of enclosing scopes become scope administrators of the current scope.
注意，范围管理员通过范围传递到其封闭范围，即封闭范围的范围管理员将成为当前范围的范围管理员。
