对您的代码进行一些修改。

这是TransferDiagram.tex为了将 Tikz 图形生成为独立图形。在数学文本中列出节点的助记名称并不方便。

main.tex这是将传输图插入主文档的文件。

%% File main.tex

\documentclass[12pt,a4paper]{article}

\usepackage{graphicx}

\begin{document}    
        
\begin{figure}[ht!]
    \centering
    \includegraphics{TransferDiagram.pdf}
    \caption{The transfer diagram of HIV-TB transmission dynamic.}
