我想按字母顺序对每个组中的名称进行排序（根据符号的描述）。

答案1
你的代码很好，除了你必须调用
\Nomenclature{A}{\(c\)}{Speed of light in a vacuum}
用大括号{}而不是方括号[]。
不过，我建议进行一点小改动，使 case switch 更易于管理，而不是嵌套，从而提高效率。请注意，在 的上下文中，\ifthenelse文本中的空格必须用 表示。case 更容易扩展。~\ExplSyntaxOn

我添加了一些虚假条目以确保排序正确。
要在组名前后添加空格，您可以这样做
\ExplSyntaxOn
\RenewDocumentCommand\nomgroup{m}
{
\par\addvspace{1cm}
\item[\bfseries
\vrule width 0pt depth 1cm
\str_case:nn { #1 }
{
{A}{Physics~constants}
{B}{Number~sets}
{C}{Other~symbols}
}
]
}
\ExplSyntaxOff
我使用了 1cm 来夸大效果。请将两者更改为适合您的值。
答案2
需要进行两项变革。
首先，您不需要尝试连接两条信息来获取所需的排序键。根据 nomencl 包的文档第 2.2 节，主命令的语法\nomenclature[<prefix>]{<symbol>}{<description>}是
排序键将是 <前缀><符号>...
因此，只需更改：
\newcommand\Nomenclature[3]{\nomenclature[#1,#3]{#2}{#3}}
到
\newcommand\Nomenclature[3]{\nomenclature[#1]{#2}{#3}}
（另外，即使您必须自己连接这些值，您想要的也是 #1、#2。）
其次，当您使用新命令时，第一个参数周围有方括号，而您需要使用花括号。因此只需更改：
\Nomenclature[A]{\(c\)}{Speed of light in a vacuum}
到
\Nomenclature{A}{\(c\)}{Speed of light in a vacuum}
您将获得此输出。无需进行其他更改。
