我正在尝试写一个涉及费曼图总和的方程，这个方程看起来像“img1 + img2 + ... = a”，其中每个图像都是像我上一个问题中的图表（定义 Tikz 图形中边缘的轨迹)。当我编译方程式时，第一个图表以文本形式出现，而其他图表都正常，我该如何解决这个问题？

输出结果如下：
开头的文本是第一个图表的代码，它按原样编译，而不是显示实际图表。我尝试了评论中的建议，但还没有奏效。我刚刚注意到，如果我在 $$ 符号之间写方程式而不是方程式环境，它确实会起作用，并且所有图表都会显示出来

答案1
如果您tikzpicture在文档序言中没有定义选项
\tikzset{T/.style = {baseline = -0.5ex,
nb/.style={sloped,below, font=\tiny},
na/.style={sloped,above, font=\tiny},
scale=0.3}
}
并添加比您的 MWE 编译的tikzpicture选项：[T]luaLaTeX
（没有错误，没有警告，没有坏框）
