如果要用数学模式插入一个变量或者一个函数名, 且这个变量或函数名包含多个字母, 则一般推荐用\mathrm的格式, 比如:
$\mathrm{c}\mathrm{o}\mathrm{u}\mathrm{n}\mathrm{t}\leftarrow 1$: (\mathrm{count}\gets 1)
$\mathrm{p}\mathrm{r}\mathrm{o}\mathrm{m}\mathrm{o}\mathrm{t}\mathrm{e}\_\mathrm{f}\mathrm{l}\mathrm{o}\mathrm{w}(...)$: (\mathrm{promote_flow(…)})
