amsmath 中的垂直对齐方式

我有以下内容：

\documentclass{article}
\usepackage{amsmath}
\begin{document}

     \begin{align*}
     &\pi(x)       & \parbox{8cm}{Lorem ipsum dolor sit amet, harum electram vim ut. Recusabo expetenda sententiae an nam. Ut has laudem graeco invenire. }   \\
     &\psi(y)      & \parbox{8cm}{Lorem ipsum dolor sit amet, harum electram vim ut. Recusabo expetenda sententiae an nam. Ut has laudem graeco invenire. }   \\
     &\tau(z)      & \parbox{8cm}{Lorem ipsum dolor sit amet, harum electram vim ut. Recusabo expetenda sententiae an nam. Ut has laudem graeco invenire. }   \\
     \end{align*} 

\end{document}

我正在尝试解释左侧表达式的一些内容。如何垂直对齐表达式及其相应的解释？

如果混合 amsmath aligned 和 parbox 不是正确的方法？你有什么建议？

答案1

align这里的环境是错误的，您最好使用表格或列表，列表的优势在于您可以在自然点进行分页，即使那是在项目描述的一半。可以使用enumitem我已加载的包轻松控制列表格式，但这里只使用默认布局。

\documentclass{article}
\usepackage{amsmath,array,enumitem}
\begin{document}

     \begin{tabular}{>$l<$p{8cm}}
     \pi(x)       & Lorem ipsum dolor sit amet, harum electram vim ut. Recusabo expetenda sententiae an nam. Ut has laudem graeco invenire.    \\
     \psi(y)      & Lorem ipsum dolor sit amet, harum electram vim ut. Recusabo expetenda sententiae an nam. Ut has laudem graeco invenire.    \\
     \tau(z)      & Lorem ipsum dolor sit amet, harum electram vim ut. Recusabo expetenda sententiae an nam. Ut has laudem graeco invenire.    \\
     \end{tabular} 


\begin{description}
     \item[$\pi(x)$]  Lorem ipsum dolor sit amet, harum electram vim ut. Recusabo expetenda sententiae an nam. Ut has laudem graeco invenire.    
     \item[$\psi(y)$]  Lorem ipsum dolor sit amet, harum electram vim ut. Recusabo expetenda sententiae an nam. Ut has laudem graeco invenire.    
     \item[$\tau(z)$] Lorem ipsum dolor sit amet, harum electram vim ut. Recusabo expetenda sententiae an nam. Ut has laudem graeco invenire.   
     \end{description} 

\end{document}
