Tikz-Feynman 图在子图中重叠

我想并排显示三个费曼图。我使用 subfigure 环境。但是，第二张和第三张图的顶点标签重叠。我尝试使用参数[scale=0.5]缩小图表，\begin{tikzpicture}但之后没有任何效果。我该如何缩小这里的图表？

         \vertex [above right=of v1] (o0) {\(p_1,m_1\)};
         \vertex [right=of v1] (o1) {\(p_2,m_2\)};

这些图比 更宽0.3\textwidth。一个简单的方法是使用\begin{tikzpicture}[scale=0.75,every node/.style={transform shape}]

关键transform shape是将变换（缩放）应用于每个节点。

\scalebox也有效

\scalebox{0.75}{\begin{tikzpicture}
...
\end{tikzpicture}}
