从属类型是运行时值参数化的类型(与泛型比较，泛型是其它类型参数化的类型)。

Dependent types are types parameterized by run-time values (compare this with generic types, which are parameterized by other types).

提取通用行为并把它们包含在泛型 DAO 中，让类的所有用户通过泛型 DAO 访问这些功能，这样就可以减少代码重复。

You can reduce code duplication by abstracting the common behavior and including it in the generic DAO, where all users of the class will have access to the functionality.

因为我想在这一期中演示泛型的解码，所以类型信息需要包含泛型引用所使用的具体的参数类型。

Because I want to demonstrate decoding generic types for this column, the type information needs to include the specific parameter types used with a generic type reference.
