The idea is that you can instantiate a Scope in one method with an instance of type t that you'd like another method later in the call stack to be able to access.

您可以在一个方法中使用类型t的一个实例来实例化s cope，并希望调用堆栈中的另一方法稍后能够访问该实例。

Scope also supports nesting, meaning that internally it maintains a stack of instances of type t and exposes the instance at the top of the stack through the Current property.

Scope也支持嵌套，即在内部，它保留类型t的实例堆栈，并通过Current属性将实例暴露在堆栈顶部。

With its narrow operating frequency scope and low measuring precision, traditional phase difference measuring system can 't satisfy the requirement of modern phase array technology.

传统的相位差测量系统，因其工作的频段窄，测量精度低，已不能满足现代相控阵技术的要求。
