你可以用 来获得它。如果你用开关(MiKTeX) 或(TeX Live, MacTeX)启动它pstricks，它就可以被编译。pdflatex--enable-write18--shell-escape

\documentclass[border=3pt, x11names]{standalone}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}%
\usepackage{lmodern}
\usepackage{mathtools}
\usepackage{pstricks-add}
\usepackage{auto-pst-pdf}
\pagestyle{empty}

\begin{document}

\begin{pspicture}(-2,-6)(7,6)
    \everypsbox{\scriptsize}
    \psset{linewidth=0.5pt, dotsize=4pt, linecolor=SlateGray3, yunit=0.5, arrowinset=0.15, shortput=nab, linejoin =1}
    \multido{\i=2 + 1}{4}{\dotnode[href = 2ex, vref = 2ex](0,\i){A\i}}
    \multido{\i=2 + 1}{4}{\dotnode[href = 2ex, vref = 2ex](0,-\i){B\i}}
    \pnodes(-1ex,5){A’}(-1ex,-5){B’}
    \psset{yunit=1.33}
    \multido{\i=1+1}{4}{\dotnode(4,\i){C\i}}
    \pnodes(4.15,4){D}(4.15,1){C}
    \uput[u](0,4.5){\em item}
    \uput[u](4,4.5){\em container}
    \psset{linecolor=black, arrows=-> , arrowinset=0.15, labelsep=1pt, npos=0.6}
    \ncline{A5}{C4}\naput{$1$}
    \ncline{A5}{C3}\naput{$2$}
    \ncline{A5}{C2}\naput{$3$}
    \ncline{B5}{C1}\naput{$\mathrm {j\times i}$}
    \psset{braceWidthInner=3pt,braceWidthOuter=3pt, braceWidth =0.6pt, nodesepA =-5pt}
    \psbrace[rot=180](A’)(B’){$ j $}
    \psbrace[nodesepA=1pt](C)(D){$ i $}
    \psset{linestyle=dotted, linewidth=0.8pt, linecolor=black, arrows=-, nodesep=8pt}
    \ncline{A2}{B2}
    \pcline[offset=2.4cm, nodesep =-3pt](C1)(C2)
\end{pspicture}

luamplib这是使用 TeX Gyre Termes 字体完成的版本。使用 进行处理lualatex。

vardef vbrace(expr a,b,n,m,s) =
