子浮点中的错误引用

Question

最近我问了一个问题caption关于的不兼容性revtex4-2。我采纳了建议，但现在我面临新的问题，例如：

1. 文本中和文本下方的图形数字样式之间的差异
2. 我想将图片并排放置。我附加了文件（我不知道如何附加图片）

通过以上代码与您的代码的比较您应该观察到：

• 图表标签应位于标题之后
• 您的问题的 MWE 可以显著缩短
• 它也适用于最近的subcaption软件包（版本 1.3 或最新版本）
• 您不需要加载graphics包（它由加载graphicx）。
• 请为图像加载示例图像，该图像可供所有人使用

附录：

例如，如果您希望图中的图像跨越文档的列，则需要使用figure*浮动。例如：

\documentclass[aps,pra,twocolumn,floatfix,footinbib,notitlepage,superscriptaddress,groupaddress,subcaption,caption,showpacs]{revtex4-2}
