这个想法是

其中\E{#1}{<number>}代表你的#<number>。
检查函数定义，因为我收到 gnuplot 错误；扩展版本似乎是
( (x/10^3)*exp(-((-10))/(1))+((x/10^3)**2)* exp(2*(-((-10)))/(1))*(1)*exp((
0)/(1) + (x/10^3)*exp(-((-10))/(1))* (1)*exp(-(0)/(1))*(1)*exp((0)/(1)) )/ ( 1
+2*(x/10^3)*exp(-((-10))/(1))+((x/10^3)**2)* exp(2*(-((-10)))/(1))*exp((0)/(1))
+ 2*(1)*exp(-(0)/(1)) + exp( (0)/(1) )*( (1)*exp(-(0)/(1) ) )^2 + 2*(x/10^3)
*exp(-((-10))/(1))*(1)*exp(-(0)/(1) )* exp((0)/(1)) )
