     We shouldn't show errors for a new hero before the user has had a chance to edit the value.
     The checks for `dirty` and `touched` prevent premature display of errors.

     ### Why declare _angular_ as _any_?
     
+    ### 为何将*Angular*声明为*any*？

     A strongly typed `angular` reference to Angular 1 would be great.
     But we can't import its <a href="https://github.com/Microsoft/TypeScript/wiki/What's-new-in-TypeScript#support-for-umd-module-definitions" target="_blank">UMD typings</a>
     library, `@types/angular`, without also importing Angular 1 itself via `import * as angular from 'angular'`.
 
+    如果能在Angular 1中使用强类型的`angular`引用就太好了！
+    但是在不同时通过`import * as angular from 'angular'`导入Angular 1本身时，我们不能导入Angular 2的 <a href="https://github.com/Microsoft/TypeScript/wiki/What's-new-in-TypeScript#support-for-umd-module-definitions" target="_blank">UMD类型</a>库`@types/angular`。

     Angular 1 is currently loaded by a script tag in `index.html` and 
     switching to an ES6 import at this time is not worth the considerable effort.
     Instead we declare `angular` as an untyped `any` to avoid typing errors.
 
+    Angular 1目前是被`index.html`里的脚本标签加载的，目前不值得将其切换到ES6导入。
+    我们声明`angular`为无类型的`any`来防止类型错误。
