自定义图形/方案编号

Question

我目前正在撰写化学领域的论文。在我的实验部分，我提出了一些方案，我想知道是否可以以及如何自定义这些方案的编号。更具体地说：我想将这些方案编号为“方案 Ex”，x 为方案的编号（从 1 开始；因此方案 E.1、方案 E.2、方案 E.3，...）。这种自定义编号应该只从实验部分开始，因此 LaTeX 文档前面部分的方案应该以正常方式编号。

我的基本文档如下所示：

Answer 1

由于自动chemstyle加载chemscheme，我已经评论过chemscheme。chemscheme使用scheme计数器来控制方案。

你可以这样做

\chapter{Experimental part}
\renewcommand*{\thescheme}{E.\arabic{scheme}}%
\setcounter{scheme}{0}

就在实验部分开始的地方。
