此泛用型交流伺服控制架构主要包含三个控制迴路：电流控制迴路、解耦控制迴路与伺服控制迴路。
The proposed UAC scheme consists of three main control loops: current control, decoupling control, and servo control.
可以将泛型类型看作是类型“函数”；它们通过类型变量进行参数化，这些类型变量可以根据上下文用各种类型参数进行实例化。
Generic types can be thought of as type "functions"; they are parameterized by type variables that can then be instantiated with various type arguments depending on context.
就像泛型类的类型参数用尖括号括起来那样，泛型类型应用程序的参数也是用尖括号括起来的。
Just as the type parameters of a generic class are wrapped in Angle brackets, the arguments of a generic type application are wrapped in Angle brackets as well.
再提一次，那是因为一个泛型类可以用其自己的类型参数来实例化另一个泛型类。
Again, that's because one generic class may instantiate another with its own type parameters.
因为运行时不能区分List和List(运行时都是List)，用泛型类型参数标识类型的变量的构造就成了问题。
Because the runtime cannot tell a List from a List (at runtime, they're both just Lists), constructing variables whose type is identified by a generic type parameter is problematic.
擦除的另一个后果是，对泛型类型参数是用强制类型转换或者instance of毫无意义。
Another consequence of erasure is that using casts or instanceof with generic type parameters doesn't make any sense. The following code will not improve the type safety of your code at all.
