1. 问题描述

遇到的问题长这样。

辅助指的是中文摘要；文摘指的是英文摘要。

问题说明，每次保存完，都会出现两个多余的空行；你删除了，保存再打开，又出现了两个空行。

2 问题原因

2.1 粘贴摘要操作

如果你的电脑安装了Grammer插件的话，即使你什么也没写，如下图：

点一下保存，再回到系统：

2.2 查看错误源码

你会看到多出来了两个空行：

然后查看源码，会发现如下内容：

并且你每保存一次，就会多两个空行。

分析这些源码，可以发现，grammar出现了很多次；再一想，我的浏览器装有grammer插件，问题锁定，就是grammer捣的鬼。

2.3 查看正确的源码

正常的源码应该是长这样：

<p>

你的摘要</p>

3 解决方案

解决方案也很简单，找一个洁净的浏览器；所谓洁净指的是没装任何插件，在我们这里就是不要装Grammer的浏览器插件的浏览器。重新粘贴你的摘要进去即可。
