+ * 代表一个可用来实例化内嵌视图的内嵌模板。
+ *
  * You can access a `TemplateRef`, in two ways. Via a directive placed on a `<ng-template>` element
  * (or directive prefixed with `*`) and have the `TemplateRef` for this Embedded View injected into
  * the constructor of the directive using the `TemplateRef` Token. Alternatively you can query for
  * the `TemplateRef` from a Component or a Directive via {@link Query}.
  *
+ * 你可以用两种方式访问 `TemplateRef`。通过一个放在 `<ng-template>` 元素上的指令（或带有 `*` 前缀的指令），
+ * 可以用 `TemplateRef` 作为令牌把它的内嵌视图注入到该指令的构造函数中。
+ * 你还可以在组件或指令中通过 {@link Query} 来查询 `TemplateRef`。
+ *
  * To instantiate Embedded Views based on a Template, use {@link ViewContainerRef#
  * createEmbeddedView}, which will create the View and attach it to the View Container.
  *
+ * 要想实例化一个基于模板的内嵌视图，可使用 {@link ViewContainerRef# createEmbeddedView}，该方法会创建一个视图，
+ * 并把它挂到所属的视图容器中。
