厦门大学LaTeX模板：封面头

   {\songti \zihao{-4} \noindent \bfseries 
  	\parbox[l]{0.5\textwidth}{\raggedright \XMU@label@serialnumber \XMU@value@serialnumber}  
    \parbox[r]{0.5\textwidth}{\raggedleft
        \XMU@label@classification\XMUunderline[45pt]{\XMU@value@classification}
  		\XMU@label@confidential\XMUunderline[45pt]{\XMU@value@confidential}} 
   }\\
   {\songti \zihao{-4} \bfseries  
    \parbox[l]{0.5\textwidth}{\raggedright\XMU@label@studentnumber  \XMU@value@studentnumber}  
    \parbox[r]{0.5\textwidth}{\raggedleft\XMU@label@UDC\XMUunderline[45pt]{\XMU@value@UDC}}
   }

由于格式更改，新的封面头为

  { 
   {\songti\zihao{-4} \noindent\bfseries \XMU@label@serialnumber \XMU@value@serialnumber } \\
   {\songti\zihao{-4} \bfseries  \XMU@label@studentnumber  \XMU@value@studentnumber}
  }
