-## Associated types
-The use of "Associated types" improves the overall readability of code by moving inner types locally into a trait as output types. For example :
+## 关联类型
+关联类型主要用于提升代码的可读性，例如以下代码 :
 ```rust
 pub trait CacheableItem: Clone + Default + fmt::Debug + Decodable + Encodable {
   type Address: AsRef<[u8]> + Clone + fmt::Debug + Eq + Hash;

-Using of `Address` is much more clearable and convenient than `AsRef<[u8]> + Clone + fmt::Debug + Eq + Hash`.
+相比 `AsRef<[u8]> + Clone + fmt::Debug + Eq + Hash`， `Address` 的使用可以极大的极少其它类型在实现该特征时所需的模版代码.
