如何使编号标签变得更大?

如何使编号标签变得更大?

目前,我正在使用此代码。我使用了 scriptsize 命令,以便某些分数不会占满页面。

\documentclass[letterpaper,12pt]{article}
\begin{document}
\begin{scriptsize}
\begin{align}
   \nonumber &E_{PP}^* = (S_b^*, I_b^*, S_h^*, I_a^*, R_h^*) = \Big(\frac{H_b(\mu_b + \delta_b) + \Lambda_b}{\mu_b + \beta_b}, \frac{\beta_b\Lambda_b - H_b\mu_b(\mu_b + \delta_b)}{(\mu_b + \delta_b)(\mu_b + \beta_b)},\\ \nonumber &\frac{\Lambda_h[\beta_b\Lambda_b-H_b\mu_b(\delta_b+\mu_b)+H_{bh}(\beta_b+\mu_b)(\delta_b+\mu_b)]}{\mu_b(\delta_b+\mu_b)[\beta_{bh}(cq-1)H_b-H_b\mu_h+H_{bh}\mu_h]+\beta_b\big\lbrack\beta_{bh}(\Lambda_b-cq\Lambda_b)+\mu_h[H_{bh}(\delta_b+\mu_b)+\Lambda_b]\big\rbrack},\\\nonumber
     &-\frac{\beta_{bh}(cq-1)\Lambda_h[\beta_b\Lambda_b-H_b\mu_b(\delta_b+\mu_b)]}{(\gamma_a+d+\mu_h)\Big\lbrack\mu_b(\delta_b+\mu_b)[\beta_{bh}(cq-1)H_b-H_b\mu_h+H_{bh}\mu_h]+\beta_b\big\lbrack\beta_{bh}(\Lambda_b-cq\Lambda_b)+\mu_h[H_{bh}(\delta_b+\mu_b)+\Lambda_b]\big\rbrack\Big\rbrack},\\\nonumber
     &-\frac{\beta_{bh}\gamma_a(cq-1)\Lambda_h[\beta_b\Lambda_b-H_b\mu_b(\delta_b+\mu_b)]}{\mu_h(\gamma_a+d+\mu_h)\Big\lbrack\mu_b(\delta_b+\mu_b)[\beta_{bh}(cq-1)H_b-H_b\mu_h+H_{bh}\mu_h]+\beta_b\big\lbrack\beta_{bh}(\Lambda_b-cq\Lambda_b)+\mu_h[H_{bh}(\delta_b+\mu_b)+\Lambda_b]\big\rbrack\Big\rbrack}\Big).\\\label{Eqn: PPEE}
\end{align}
\end{scriptsize}

输出如下: 在此处输入图片描述

我想让数字标签 (67) 采用常规字体,而不是采用 scriptsize 字体。有办法解决这个问题吗?

答案1

无论您是否想使用方程编号,我建议如果您像这样写这些方程,读者会更容易理解:

在此处输入图片描述

你可能不想把它分开这么多,但你绝对应该给这些方程式分母的公共部分命名,这样更容易理解。(这个X,或者无论你想叫它什么,都可能很“重要”,因为它出现在很多地方。)正如评论中所述,scriptsize应尽可能避免使用。

完整代码:

\documentclass[letterpaper,12pt]{article}
\usepackage{amsmath}
\begin{document}
   Now, $E_{PP}^*= (S_b^*, I_b^*, S_h^*, I_a^*, R_h^*)$, where
   \begin{align}
  S_b^* &= \frac{H_b(\mu_b + \delta_b) + \Lambda_b}{\mu_b + \beta_b},\\
  I_b^* &=\frac{\beta_b\Lambda_b - H_b\mu_b(\mu_b + \delta_b)}{(\mu_b + \delta_b)(\mu_b + \beta_b)},\\
  S_h^* &=\frac{\Lambda_h[\beta_b\Lambda_b-H_b\mu_b(\delta_b+\mu_b)+H_{bh}(\beta_b+\mu_b)(\delta_b+\mu_b)]}{X},\\
  I_a^* &=-\frac{\beta_{bh}(cq-1)\Lambda_h[\beta_b\Lambda_b-H_b\mu_b(\delta_b+\mu_b)]}{(\gamma_a+d+\mu_h)X},\\
  R_h^*  &=-\frac{\beta_{bh}\gamma_a(cq-1)\Lambda_h[\beta_b\Lambda_b-H_b\mu_b(\delta_b+\mu_b)]}{\mu_h(\gamma_a+d+\mu_h)X},\\
   \intertext{and}
   X&=\mu_b(\delta_b+\mu_b)[\beta_{bh}(cq-1)H_b-H_b\mu_h+H_{bh}\mu_h]+\\\nonumber
  & \quad+\beta_b\big\lbrack\beta_{bh}(\Lambda_b-cq\Lambda_b)+\mu_h[H_{bh}(\delta_b+\mu_b)+\Lambda_b]\big\rbrack

  \end{align}

\end{document}

答案2

我建议采用这种布局,基于alignedat和使用mathtoolsnccmath(适用于中等大小的分数)和geometry(如果不使用边注,则可以获得更合适的水平边距):

\documentclass[letterpaper,12pt]{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[showframe]{geometry}
\usepackage{mathtools, nccmath}

\begin{document}

\vspace*{1cm}
\begin{equation}\label{Eqn: PPEE}
\begin{alignedat}{2}
 &\mathrlap{ E_{PP}^* = (S_b^*, I_b^*, S_h^*, I_a^*, R_h^*) = \biggl(\mfrac{H_b(\mu_b + \delta_b) + \Lambda_b}{\mu_b + \beta_b}, \mfrac{\beta_b\Lambda_b - H_b\mu_b(\mu_b + \delta_b)}{(\mu_b + \delta_b)(\mu_b + \beta_b)}}, & &\\%
  & & \mfrac{\Lambda_h[\beta_b\Lambda_b-H_b\mu_b(\delta_b+\mu_b)+H_{bh}(\beta_b+\mu_b)(\delta_b+\mu_b)]}%
   {\begin{rcases}\splitfrac{\rule{0pt}{2ex}\,\mu_b(\delta_b+\mu_b)\bigl[\beta_{bh}(cq-1)H_b-H_b\mu_h+H_{bh}\mu_h\bigr]}{+\beta_b\bigl[\beta_{bh}(\Lambda_b-cq\Lambda_b)%
   + \mu_h \bigl(H_{bh}(\delta_b+\mu_b)+\Lambda_b\bigr)\bigr]}\end{rcases}{\textstyle \rlap D}} & ,\\[0.5ex] %
    & & -\mfrac{\beta_{bh}(cq-1)\Lambda_h\bigl[\beta_b\Lambda_b-H_b\mu_b(\delta_b+\mu_b)\bigr]} %
     {(\gamma_a+d+\mu_h)D},%
     -\mfrac{\beta_{bh}\gamma_a(cq-1)\Lambda_h\bigl[\beta_b\Lambda_b-H_b\mu_b(\delta_b+\mu_b)\bigr]}%
     {\mu_h(\gamma_a+d+\mu_h)D}\biggr) & .
\end{alignedat}
\end{equation}

\end{document} 

基于 <code>alignedat</code>
