我的投影仪幻灯片的背景有问题。当我在 PC（Windows 7，TeXLive 2015）上编译它时，我得到以下背景：
但是当我在 MacBook（Mojave，TeXLive 2018）上编译它时，我得到了以下背景：
我该如何修复它才能获得第一个？

答案1
你首先设置了黄红色背景，但后来你用\setbeamertemplate{background canvas}[vertical shading][bottom=red!10,top=blue!10]
如果删除这条线，就会得到黄红色的阴影。
关于您的代码的其他一些评论：
第一张图片中阴影的阴影不正确，表明您的 beamer 版本严重过时。您应该更新您的 tex 发行版
beamer 选项
red已过时。请\usecolortheme[rgb={0.7,0.2,0.2}]{structure}使用你不需要
xcolor，graphicx或者url用投影仪不要多次加载包
使用 beamer进行加载没有什么意义
multicol，因为 beamer 有自己的柱状机构你不应该
epsfig在本世纪写的任何文件中使用times已经过时了，有更好的 times 字体包而不是
colortbl更好地将xcolor={table}documentclass 选项传递给 beamer可选参数后的换行符
\date毫无意义，且缺少强制参数
% !TeX TS-program = xelatex
