我正在尝试使用热力学模块等来显示焓,但似乎不起作用。
\documentclass[twocolumn]{article}
\usepackage{chemmacros}
\usechemmodule{all}
\begin{document}
\enthalpy*(r){1}
\end{document}

以下内容适用于 v5.0 之前的版本和当前版本:
\documentclass{article}
\usepackage{chemmacros}
% versions below 5.0 don't have the macro. Let's provide it
% to expand to the “false” branch if it isn't defined:
\providecommand\IfChemCompatibilityTF[4]{#4}
% let's check if the current version of chemmacros (or rather the
% compatibility mode it is used with) is 5.0 or newer:
\IfChemCompatibilityTF{>=}{5.0}{
% load all the modules we need. “all” is overkill but will do:
\usechemmodule{all}
}{
% in the new versions \Enthalpy is called \enthalpy. Let's
% take care we can use the same command either way:
\let\enthalpy\Enthalpy
}
\begin{document}
\enthalpy*(r){1}
\end{document}
