乳胶图形；当绘制四部分图形时，其中一个(b)比另一个高，我找不到任何原因

Question

​

​

我正在用latex写一篇文章，出于某种原因，我的一个人物神秘地漂浮在周围。我试着制作四个数字中的一个(a，b，c，d)，而b数字只是浮动在它应该在的位置上。我已经检查了图形大小和定义图形后的任何额外标志，但似乎找不到问题。

有没有人看到问题出在哪里？

Answer 1

subfigure环境的第一个可选参数用于外部位置。实际上，b和c是允许的值，其他值将默认为c。您的第二个图像未对齐，因为您指示它底部对齐。

其他一些评论：

• mathtools已经加载了amsmath

• load hyperref after the other packages

如果还加载hyperref，则

• 不需要url

• subcaption已经加载了caption
