结果：

输入文件：虚拟位移系统，虚拟位移自由体图和虚拟位移。

有没有办法通过A上图中的点将三张图片对齐？简而言之：

wished result

提前感谢您的帮助和努力！

答案1

这是另一个我无法解释为什么事情会失败的案例，但我可以指出如何使其发挥作用。

不要使用\\[\baselineskip]（这无论如何都是不受欢迎的），而是通过在图表前后添加一行空代码来开始一个新段落。（如果你总是添加\\[baselineskip]你做错的事情，我认为正确的方法是使用\documentclass[parskip=full]{scrartcl}，并用空行开始新段落。）

首先考虑这个简化的例子：

\documentclass{article}
\usepackage{tikz}
\usepackage{showframe} % to indicate text area bounds
\usepackage{parskip} % set zero parindent and some parskip

\newcommand\demodiagram[1]{%
\begin{tikzpicture}[trim left=(a)]
\coordinate (a);
\fill (a) circle[radius=2pt];
\draw [<->] (a) +(-#1,0) -- +(2*#1,0);
\end{tikzpicture}}
\begin{document}
Here we have paragraph breaks before and after the diagrams.

\demodiagram{1}

\demodiagram{2}

And it works as expected.

But this\\
\demodiagram{1}\\
does not\\
\demodiagram{2}\\
work.
\end{document}

输出如下所示：

result of above code

因此，您可以看到，由于您使用的结构（即使用 的换行符）的原因，此操作失败\\。

用您的代码完成示例。

在下面的代码块中，我为您的代码实现了相同的功能，但我还演示了第二种方法，即添加类似于

\useasboundingbox (-2,2.5) rectangle (7.5,-1);

在每个 的开头tikzpicture。当在图表的最开始处添加时，这可以让您手动设置边界框。要对齐多个图表，您只需确保第一个坐标的 x 分量在所有tikzpictures 中都相同。其他值需要针对每个图表单独调整。

这种方法不如 方便trim left，但好处是图表不会突出到左边距。（取决于您为最左边的坐标选择的 x 值。）

% note the parskip=full parameter which disables paragraph indentation
% and sets some vertical space between paragraphs.
