图片和文本块

Question

我做学校项目，里面有 circuitikz 电路和每个电路的一些方程式。我想把它们放在一起，把图片放在左边，把方程式放在右边——就像附图一样。也不想让块覆盖前一个。试过多列，但它强制两列宽度相同，也不允许我在方程式上方添加任何空间。有什么想法吗？谢谢。看起来

\begin{multicols}{2}
\centering
\resizebox{8cm}{!}{
    \begin{circuitikz} \draw
      (0,0) to[dcvsource, l=$U_{12}$] (0,4)
      %connect 0,0 with R1
      (0, 4) -- (0.75, 4)
      to[R, *-*, l=$R_{12}$] (4,4)
      %parallel R1,2, R3
      (0.75,4) -- (0.75,2)
      to[R, -*, l=$R_3$] (4,2)

      to[R, l=$R_4$] (4, 4)

      to[R, l=$R_5$] (8, 4)

      (8,4) -- (8,0)
      (4,2) -- (4, 2)
      to[R, -*, l=$R_6$] (8,2)
      (8, 0) -- (4, 0)
      to[R, l=$R_{78}$]
      (2, 0) -- (0,0)
    ;
    \end{circuitikz}
}
\columnbreak
\begin{itemize}
    \item $R_{12} = R_1 + R_2$
    \item $U = U_1 + U_2$
\end{itemize}
\end{multicols}

Answer 1

那这个呢？

\documentclass[11pt,a4paper]{report}
\usepackage{amsthm,amsmath,amssymb,amsfonts}
\usepackage{circuitikz}
\usepackage{showframe}
\begin{document}
Using \verb|\parbox[text]{width}{text}|:

\parbox[c]{.5\linewidth}{%
\begin{circuitikz}[scale=.6] \draw
      (0,0) to[dcvsource, l=$U_{12}$] (0,4)
      %connect 0,0 with R1
      (0, 4) -- (0.75, 4)
      to[R, *-*, l=$R_{12}$] (4,4)
      %parallel R1,2, R3
      (0.75,4) -- (0.75,2)
      to[R, -*, l=$R_3$] (4,2)

      to[R, l=$R_4$] (4, 4)

      to[R, l=$R_5$] (8, 4)

      (8,4) -- (8,0)
      (4,2) -- (4, 2)
      to[R, -*, l=$R_6$] (8,2)
      (8, 0) -- (4, 0)
      to[R, l=$R_{78}$]
      (2, 0) -- (0,0)
    ;
    \end{circuitikz}
}%
\parbox[c]{.5\linewidth}{%
\begin{itemize}
    \item $R_{12} = R_1 + R_2$
    \item $U = U_1 + U_2$
\end{itemize}
}

Or using \verb|\begin{figure*}[placement] \end{figure*}|:
\begin{figure*}[h]\centering
\begin{circuitikz}[scale=.6] \draw
      (0,0) to[dcvsource, l=$U_{12}$] (0,4)
      %connect 0,0 with R1
      (0, 4) -- (0.75, 4)
      to[R, *-*, l=$R_{12}$] (4,4)
      %parallel R1,2, R3
      (0.75,4) -- (0.75,2)
      to[R, -*, l=$R_3$] (4,2)

      to[R, l=$R_4$] (4, 4)

      to[R, l=$R_5$] (8, 4)

      (8,4) -- (8,0)
      (4,2) -- (4, 2)
      to[R, -*, l=$R_6$] (8,2)
      (8, 0) -- (4, 0)
      to[R, l=$R_{78}$]
      (2, 0) -- (0,0)
    ;
    \node[right] at (9,3) {\textbullet\ $ R_{12} = R_1 + R_2$};
    \node[right] at (9,1) {\textbullet\ $U = U_1 + U_2$};
\end{circuitikz}
\end{figure*}

\end{document}

Answer 2

问题在于，为了保持左右连贯性，你必须进行大量的视觉设计，而这并不是 LaTeX 的强项。我通常使用的是wrapfigure，但它有其注意事项（有时会表现得很奇怪，你必须强制使用它，你会在这里找到很多关于它的问答）。例如（直接来自我的课程材料）：

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[spanish]{babel}\deactivatequoting
\usepackage{wrapfig}
\usepackage[siunitx]{circuitikz}
\usepackage{amsmath}
\newcommand{\shunt}{\mathop{/\!/}}
\parindent=0pt
\begin{document}

bla blah blah blah blah, 
para obtner:

\begin{wrapfigure}{l}{0.5\textwidth}
        \begin{circuitikz}[american]
            \draw (0,0) to[sV=$v_{th}$, ] ++(0,-3) node[ground](GND){}; %notice the worng +-, uffff
            \draw (0,0) to [R=${R_{th}}$] ++(2,0)
                to [C=${C}$, ] ++(1.5,0) coordinate (n2)
                to  [R=${R_L}$] (n2 |- GND) node[ground]{};
            \draw (n2) to [short, -o] ++(1,0) node [right] {$v_{o2}$};
        \end{circuitikz}
\end{wrapfigure}
y donde los equivalentes de Thévènin son:
\begin{align}
    R_{th} &= R_p\shunt r_d = \SI{667}{\ohm} \\
    v_{th} &= \frac{r_d}{R_p + r_d} v_s = \frac{2}{3}v_s
\end{align}
\dots y de paso, nota que:
\begin{equation}
    \frac{v_{o2}}{v_s}\bigg\vert_{f\to\infty} = \frac{R_L}{R_L+R_{th}} v_{th} =
    \num{0.4}v_s
\end{equation}
que lógicamente coincide con el resultado anterior.
