chemnum - 文本中的编号错误

Question

这是该答案的后续问题这里。当我将第一个方案与第二个方案结合时，文本中的编号出现了问题。如果我将文本放在位置一，编号是正确的。当我在第二个方案之后添加文本时，文本中的编号是错误的。

仅限位置 1：

仅限位置 2：

我以为第二个位置上得到的数字和第一个位置上得到的数字相同。哪里出了问题？

Answer 1

\cmpdinside of 的使用psfrag显然会弄乱相应化合物的启动/定义。您可以通过使用\cmpd*{<ID>}inside ofscheme环境自己定义新标签来防止这种情况，例如：

\begin{scheme}[htb]
\centering
\cmpd*{mycompound.a, mycompound.b, mycompound.c}
\psfrag{TMP1}{\cmpd{mycompound.a}: M = Ti, n = 4}
\psfrag{TMP2}{\cmpd{mycompound.b}: M = Fe, n = 3}
\psfrag{TMP3}{\cmpd{mycompound.c}: M = Sn, n = 4}
\includegraphics{xyz}
\caption{My compounds. The replacement text is left aligned with respect to the placeholder text.}
\label{mycompounds}
\end{scheme}

为了避免两次输入相同的ID，以及避免意外弄乱ID的顺序，您还可以定义自己的命令，如下所示：

\newcommand{\replacecmpdcomment}[3]{\cmpd*{#2}\psfrag{#1}{\cmpd{#2}: #3}}

然后您可以在文档中使用它，如下所示：

\replacecmpdcomment{<replacement tag>}{<compound's ID>}{<comment to be added>}
