我正在尝试缩放图形的大小。我们该怎么做？

Answer 1

无需缩放。只需使用正确的图像尺寸即可pspicture：

\documentclass[a4paper, 12pt, oneside]{article}
\usepackage{pst-all}
\usepackage{tikz}
\begin{document}

\begin{figure}
\centering
\begin{pspicture}[showgrid=false](-3,0)(7.5,2)
  \psline{*-*}(0,1)(2,1)\psdot(1,1)
  \psline[linestyle=dashed]{-*}(2,1)(3,1)
  \psline{-*}(3,1)(4,1)
  \psarc[linestyle=dotted](0,1){1.5}{135}{225}
  \psarc[linestyle=dotted](4,1){1.5}{-45}{45}
  \rput(0,1){\psforeach{\iA}{135,157.5,205.5,225}{\psline{-*}(1.5;\iA)}}
  \rput(4,1){\psforeach{\iA}{-45,-22.5,0,22.5,45}{\psline{-*}(1.5;\iA)}}
  \uput{10pt}[-90](0,1){$u_0$}
  \uput{10pt}[-90](1,1){$u_1$}
  \uput{10pt}[-90](2,1){$u_2$}
  \uput*{10pt}[-90](4,1){$u_{k-s-t}$}
  \rput[r](-1.5,1){$s$ vertices $\Bigg\{$}
  \rput[l](5.6,1){$\Bigg\} t$ vertices}
\end{pspicture}
\caption{The graph $\mathcal{P}(k,s,t)$}\label{pkst}
\end{figure}

\end{document}

Answer 2

您可以调整 pspicture 的大小，而不调整文本的大小——这会导致字体大小不一致，\psset{unit=...}在开始时使用（默认单位是 1cm；我在这里选择unit=0.8cm）。这是一个例子。我借此机会简化了您的代码，系统地使用了 psnodes，并附加了包pst-eucl/

    \documentclass[a4paper,, oneside]{article}

    \usepackage{pst-all, pst-eucl}

    \begin{document}

    \begin{figure}
    \psset{unit=0.8cm}
    \centering
    \begin{pspicture}(-3.5,-1.3)(7.5,1.3)
    \pstGeonode[PointName={u_0,u_1,u_2,none, u_{k-s-t},none}, PosAngle=-90](0,0){U0}(1,0){U1}(2,0){U2}(3,0){U3}(4,0){U4}(5.4,0){B0}
    \psline(U0)(U2)\psline[linestyle=dashed, dash=3pt 2pt](U2)(U3)\psline(U3)(B0)
    \foreach \ang/\i in {-50/1,-30/2,30/3,50/4}{\dotnode[PointName=none](-1.4;\ang){A\i}\AtoB(A\i)(U4){B\i} \psline(A\i)\psline[arrows=-*](U4)(B\i)}
    \pstArcOAB[linestyle=dotted]{U0}{A1}{A4}
    \pstArcOAB[linestyle=dotted]{U4}{B2}{B3}
    \pnodes[-0.8em, 0](A2){C2}(A3){C3}
    \pnodes[0.8em, 0](B2){D2}(B3){D3}
    \psset{braceWidth=1pt, braceWidthInner=3pt, braceWidthOuter=3pt}
    \psbrace[ref=rC, nodesepA=-2pt](C2)(C3){$s$ vertices}
    \psbrace[ref=lC, nodesepA= 2pt](D2)(D3){$t$ vertices}
    \end{pspicture}
    \caption{The graph $\mathcal{P}(k,s,t)$}\label{pkst}
    \end{figure}

    \end{document}
