我需要帮助创建
这张图片是 LaTeX 格式的。我尝试使用 TikZ 包来做这件事。但没有得到精确的图像。请帮忙。我非常感谢你能提供的任何帮助。

使用库中的括号decorations.pathreplacing：
\documentclass[tikz, border=20]{standalone}
\usetikzlibrary{decorations.pathreplacing}
\begin{document}
\begin{tikzpicture}
\tikzset{brace/.style = {ultra thick, decorate, decoration={brace,amplitude=10pt,mirror,raise=4pt}}}
\draw[ultra thick, <->] (0, 0) -- (10, 0);
\draw[ultra thick] (1, -0.3) -- (1, 0.3);
\draw[ultra thick] (5, -0.3) -- (5, 0.3);
\draw[ultra thick] (9, -0.3) -- (9, 0.3);
\node at (1, -0.5) {\(t_{a^{-m}}\)};
\node at (5, -0.5) {\(t_{a^{0}}\)};
\node at (9, -0.5) {\(t_{a^{m}}\)};
\draw[brace] (5, 0.5) -- (1, 0.5);
\draw[brace] (9, 0.5) -- (5, 0.5);
\node at (3, 1.5) {Non-membership (\(LS_2\))};
\node at (7, 1.5) {Membership (\(LS_1\))};
\end{tikzpicture}
\end{document}

使用马查工具（无 MWE 的用户——最小工作示例)：
\documentclass[a4paper,12pt]{article}
\usepackage{tikz}
\begin{document}
\tikzset{every picture/.style={line width=0.75pt}} %set default line width to 0.75pt
\begin{tikzpicture}[x=0.75pt,y=0.75pt,yscale=-1,xscale=1]
\draw (135,101) -- (472,101) ;
\draw [shift={(474,101)}, rotate = 180] [fill={rgb, 255:red, 0; green, 0; blue, 0 } ][line width=0.08] [draw opacity=0] (12,-3) -- (0,0) -- (12,3) -- cycle ;
\draw [shift={(133,101)}, rotate = 0] [fill={rgb, 255:red, 0; green, 0; blue, 0 } ][line width=0.08] [draw opacity=0] (12,-3) -- (0,0) -- (12,3) -- cycle ;

为了锻炼，而且因为你是新手...一个更复杂/花哨的解决方案：
\documentclass[border=3.141592]{standalone}
\usepackage{tikz}
\usetikzlibrary{arrows.meta,
decorations.pathreplacing,
calligraphy,% had to be loaded after decorations.pathreplacing
positioning}
\begin{document}
\begin{tikzpicture}[
> = Straight Barb,
BC/.style = {% Brace Calligraphic
decorate,
decoration={calligraphic brace,
raise=3pt, amplitude=6pt,
pre =moveto, pre length=1pt,
post=moveto, post length=1pt,
},
very thick, thick, pen colour={black}
},
every node/.append style = {inner sep=2pt, align=center, anchor=south}
]
\draw[thick,<->] (0,0) -- (8.8,0);
\foreach \i/\j [count=\k] in {1/$t_{a^{-m}}$, 4.5/$t_{a^{0}}$, 8/$t_{a^{m}}$}
\draw (\i,-2mm) node[below] {\j} -- ++ (0,4mm) coordinate (n\k);
%
\draw[BC] (n1) -- node[above=8pt] {Non-membership\\ $(LS_2)$} (n2);
\draw[BC] (n2) -- node[above=8pt] {Membership\\ $(LS_1)$} (n3);
\end{tikzpicture}
\end{document}
