+ * 考虑下列路由配置：
+ * `[{ path: 'user/:name', component: UserCmp }]`.
+ * 如果要链接到这个 `user/:name` 路由，你可以使用 `RouterLink` 指令。

  *
+ * 如果该链接是静态的，你可以使用下列指令：

+ *
  * If you use dynamic values to generate the link, you can pass an array of path
  * segments, followed by the params for each segment.
  *
+ * 如果你要用动态值来生成该链接，你可以传入一组路径片段，每个片段后面都可以跟一些参数。
+ *
  * For instance `['/team', teamId, 'user', userName, {details: true}]`
  * means that we want to generate a link to `/team/11/user/bob;details=true`.

+ * 比如 `['/team', teamId, 'user', userName, {details: true}]` 表示我们要生成一个到 `/team/11/user/bob;details=true` 的链接。

  * * If the first segment begins with `/`, the router will look up the route from the root of the
  *   app.
+ *
+ *   如果第一个片段用 `/` 开头，则路由器会从应用的根路由开始查找。

  * * If the first segment begins with `./`, or doesn't begin with a slash, the router will
  *   instead look in the children of the current activated route.
+ *
+ *   如果第一个片段用 `./` 开头或者没有用斜杠开头，路由器就会从当前激活路由开始查找。
