-Effect scope is an advanced API primarily intended for library authors. For details on how to leverage this API, please consult its corresponding [RFC](https://github.com/vuejs/rfcs/blob/master/active-rfcs/0041-reactivity-effect-scope.md).
+Effect 作用域是一个高阶的 API，主要服务于库作者。关于其使用细节请咨询相应的 [RFC](https://github.com/vuejs/rfcs/blob/master/active-rfcs/0041-reactivity-effect-scope.md)。

 ## `effectScope`
 
-Creates an effect scope object which can capture the reactive effects (e.g. computed and watchers) created within it so that these effects can be disposed together.
+创建一个 effect 作用域对象，以捕获在其内部创建的响应式 effect (例如计算属性或侦听器)，使得这些 effect 可以一起被处理。

 ## Intro
 
 A `*.vue` file is a custom file format that uses HTML-like syntax to describe a Vue component. Each `*.vue` file consists of three types of top-level language blocks: `<template>`, `<script>`, and `<style>`, and optionally additional custom blocks:

 We consider Vue and Web Components to be primarily complementary technologies. Vue has excellent support for both consuming and creating custom elements. Whether you are integrating custom elements into an existing Vue application, or using Vue to build and distribute custom elements, you are in good company.
 
-## Using Custom Elements in Vue
+## 使用 Vue 构建自定义元素
 
 Vue [scores a perfect 100% in the Custom Elements Everywhere tests](https://custom-elements-everywhere.com/libraries/vue/results/results.html). Consuming custom elements inside a Vue application largely works the same as using native HTML elements, with a few things to keep in mind:
