-  Used to access content [distributed by slots](/guide/components.html#Content-Distribution-with-Slots). Each [named slot](/guide/components.html#Named-Slots) has its own corresponding property (e.g. the contents of `slot="foo"` will be found at `vm.$slots.foo`). The `default` property contains any nodes not included in a named slot.

-  Accessing `vm.$slots` is most useful when writing a component with a [render function](/guide/render-function.html).
+  在使用 [render 函数](/guide/render-function.html)书写一个组件时，访问 `vm.$slots` 最有帮助。
