如果我修复了序言中的错误（参见代码中的注释），你的 tikz 就可以正常工作了。

在此处输入图片描述

\documentclass{amsart}
%\documentclass[11pt]{article}

\usepackage
% no[dvips]
{graphicx}
% no (mathtools loads this) \usepackage{amsmath}
\usepackage{mathtools}
% no! you load this later with different options \usepackage{caption}
\usepackage[b5paper,twoside,top=20mm,right=18mm,left=22mm,bottom=15mm,bindingoffset=0mm,nomarginpar]{geometry}

%NO! \usepackage{epsfig}
\usepackage[T1]{fontenc}

%No! use geometry
