Beamer 演示：字幕问题

我正在制作演示文稿，遇到了两个问题：1) 我需要使用包 subcaption 来制作子图，同时我想使用此站点的命令\setbeamertemplate{caption}{\raggedright\insertcaption\par}删除图标题前的“Figure:”。但是，当我使用包 subcaption 时，后一个命令停止工作，我仍然可以在标题前看到“Figure:” - 参见第一张图片。 在此处输入图片描述

您知道如何使“图：”消失并且仍然使用子标题包吗？

2）为什么下图中标题和图形之间的距离这么长？（代码的最后几行） 在此处输入图片描述 这个图的代码和第一个图的代码相同，所以我不明白为什么标题和图的距离会有如此大的差异。

代码如下：

除了subcaption使用包之外，您还可以简单地使用 beamers 列机制来放置图像。

请注意，您不需要使用 beamer 或 。\usepackage{graphicx}和被称为默认，因为它们是默认加载的，因此无需再次加载它们。在没有浮动对象的类中，给出浮动说明符（例如 ）是没有意义的\usepackage{hyperref}。\usepackage{xcolor}\usecolortheme{default}\usefonttheme{default}[!htb]
