答案1
假设您想保留 y 轴上的对数缩放比例，但使用ymin=0对数 y 轴则无法实现，因此我将其更改为0.1。我想您想要类似以下示例的内容。我只是手动指定了 sytick和yticklabels。这可能不是最优雅的解决方案，但至少有效。

\begin{tikzpicture}
\begin{semilogyaxis}[
xmin=0, xmax=1, ymin=0.1, ymax=1,
samples=1000,
fill=blue,
ytick={0.1,0.2,...,1},
yticklabels={0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,1}
]
\addplot[black!50,thick ]
(x,{exp(-1/2)*(1-exp((-2*x)/0.01))+(1/2)*exp(-1/2)*(1+exp((-2*x)/0.01))+(1/8)*(0.01)*exp(-1/2)*(1-exp((-2*x)/0.01))});
\addplot[red,thick ] (x,{exp(-(1/2)+x/2)+((0.01)/8)*(1-x)*exp(-(1/2)+x/2)});
\addplot[blue,thick ] (x,{-exp(-(1/2)-(2*x)/0.01)+(1/2)*x*exp(-(1/2)-(2*x)/0.01)+exp(-(1/2)+x/2)+(0.01/8)*(-exp(-(1/2)-(2*x)/0.01)+(1-x)*exp(-(1/2)+x/2))});
