我正在尝试编写一份 2 列科学报告，我想让图表出现在第二页顶部的两列上。据我所知，使用 figure* 命令应该可以解决问题，但结果却添加了分页符，并且图像在下一页上垂直居中！我该如何解决这个问题？提前谢谢您。
请注意代码中所写的文字内容。

\section{Introduction}
This is a two column document and I want an image to spread across two
columns on the SECOND page. Rather than add a load of text here, I've kept
it short, but if you run this code then you should add a load of text so
that you're on page 2 before adding the image in order to replicate the
conditions.

您没有提供测试文件，但如果您添加足够的文本来开始第 2 页，并且图形足够小以允许位于文本页面的顶部，那么它就会出现在第 2 页的顶部。我删除了，[ht]因为figure*无法放置here。
