我的代码如下:
\documentclass{book}
\usepackage{amsmath}
\begin{document}
\begin{align}
\label{eq:ocdphi}
E(\Delta\phi_{r,j}^s)&=g^s_r\tilde{\tau}_r+d\tilde{t}_r-d\tilde{t}^s-\mu_j\tilde{\iota}_r^s+\tilde{\delta}_{r,j}-\tilde{\delta}_{,j}^s+\lambda_j\tilde{z}_{r,j}^s,\\\label{eq:ocdp}
E(\Delta p_{r,j}^s)&=g^s_r\tilde{\tau}_r+d\tilde{t}_r-d\tilde{t}^s+\mu_j\tilde{\iota}_r^s+\tilde{d}_{r,j}-\tilde{d}^s_{,j},
\end{align}
\end{document}
DVI 输出\Delta
符号采用罗马字体,但在 HTML 输出中,它采用斜体字体。我该如何修复它?
我正在运行以下命令:
htlatex filename "xhtml,mathml,mathml-" " -cunihft" " -cvalidate -p"
请建议...
