图像下方高度相似的框

Question

我正在尝试在 beamer 模板上的图形下放置 2 个高度相似的框。经过多次建议，一位用户建议我使用hf-tikz。但是当我将它用于图形下的方程式时，它一直在框住上面的图像而不是方程式。

但是通过删除图像，它会绘制所需的结果：它是否与使用有关figure？

谢谢你，

Answer 1

问题与盒子无关，subcaption包裹丢失了。

这将通过日志文件中的错误显示出来。出现错误后，Latex 只能恢复到足以对文档的其余部分进行语法检查的程度，而不一定能产生合理的输出。

其他的建议：

• beamer 没有浮动机制，指定浮动说明符是没有意义的，例如[!ht]
• beamer 自动将环境内容置于中心figure，\centering没有必要
