之间会生成References一个Appendix白页，我似乎无法摆脱它：/
任何帮助是极大的赞赏
编辑
据我所知，\onecolumn 决定了白页的引入位置。如果我把它放在后面，\begin{appendices}它将Title Appendix 出现在参考文献之后，然后是白页和其余部分appendix
答案1
每个图形的子浮点数太大，无法用字母编号。可能的解决方案：用数字编号，例如（1-32），其中 1 为数字编号，32 为子浮点数：
\renewcommand\thesubfigure{\thefigure-\arabic{subfigure}}包含 32 张图片的图形大小可能超出文本块的大小。可能的解决方案：将第一张图片分成两部分，并使用包
\ContinuedFloat中的宏caption- 而不是
scale使用选项width并将其设置为表格列的宽度（我建议使用tabularx表格环境） - 对于较短的代码，请使用键
Gin来确定两个图中所有图像的大小
考虑到上述情况，两个图的代码是：
