下面的方程用lingo怎么解啊?max=17.86*n3*e3/(4/5+e3)*(1-exp(-2/3*e3-8/15))+22.99*n4*e4/(4/5+e4)*(1-exp(-2/3*e4-8/15));n=a3*n3*exp(-2/3*e3-8/15)+a4*n4*exp(-2/3*e4-8/15);n1=1.22*pow(10,11)*n/(1.22*pow(10,11)+n);n2=

结果是无界解也不是很奇怪吧
max=17.86*n3*e3/(4/5+e3)*([email protected](-2/3*e3-8/15))+22.99*n4*e4/(4/5+e4)*([email protected](-2/3*e4-8/15));
n=a3*n3*@exp(-2/3*e3-8/15)+a4*n4*@exp(-2/3*e4-8/15);
n1=1.22*10^11*n/(1.22*10^11+n);
[email protected](-4/5)*n1;
[email protected](-4/5)*n2;
n4=n3*@exp(-4/5-2/3*e3)+n4*@exp(-4/5-2/3*e4);
e3=0.42*e4;
