parameter和function后面的分号都去掉，parameter应定义为x1，x2，……，x6。
Parameter x1,x2,x3,x4,x5,x6;
Function 1.04e-2*x6^2-5.02e+05*x1*x5-3.14e+02*x1*x6+1.58e+03*x2*x5=0;
3.14e+2*x1*x6-1.58e+03*x2*x5-7.74e+03*x2*x6+1.77e+02*x3*x5=0;
7.74e+3*x2*x6-1.77e+02*x3*x5-2.70e-04*x3^2+7.30e+06*x4*x6-6.50e-03*x2*x3+ 6.26e+06*x4*x5=0;
1.35e-4*x3^2-3.65e+06*x4*x6+ 6.50e-03*x2*x3-6.26e+06*x4*x5-3.16e+14*x4=0;
1.04e-2*x6^2+3.14e+02*x1*x6-1.58e+03*x2*x5+7.74e+03*x2*x6-1.77e+02*x3*x5-9.74e+05*x5^2+6.50e-03*x2*x3-6.26e+06*x4*x5=0;
2.56e-10*x6+x1+x2+x3+x4+x5+x6=1;
