![将多列研究论文切换为双列研究论文,创建间隙并在下一页开始双列](https://linux22.com/image/452800/%E5%B0%86%E5%A4%9A%E5%88%97%E7%A0%94%E7%A9%B6%E8%AE%BA%E6%96%87%E5%88%87%E6%8D%A2%E4%B8%BA%E5%8F%8C%E5%88%97%E7%A0%94%E7%A9%B6%E8%AE%BA%E6%96%87%EF%BC%8C%E5%88%9B%E5%BB%BA%E9%97%B4%E9%9A%99%E5%B9%B6%E5%9C%A8%E4%B8%8B%E4%B8%80%E9%A1%B5%E5%BC%80%E5%A7%8B%E5%8F%8C%E5%88%97.png)
我下载了一个模板来写研究论文。这是一个多列(两列)模板,但由于多列(伪代码和其他表格),这个模板无法工作(除了文本和图片外,不显示任何内容)。我将多列文档切换为两列文档,伪代码和表格现在可以正常工作了。但在摘要之后,介绍显示在旁边,摘要之后整个页面都是空白的,我正在分享图片和代码。
代码如下

The Android Operating System is used on more than 2.8 billion smartphones. Only last year, over 1.05 billion Android phones were shipped. Among mobile phone users, over 75\% use Android smartphones due to their low prices and open-source operating systems, which make up the most popular operating system. Smartphones are no longer just for communications; they have evoloved into one of lifes necessities. An average person spends 5 to 6 hours daily on mobile devices, including browsing, social media, and online purchasing apps. The Android platform offers a free play store to download applications.
