希望有1stopt 2.0 以上的高手帮小妹一个忙，深表感激

1.5下编的，感觉sharemodel 不起作用，希望有更高版本的高手帮忙运算一下，小妹在此先谢过了！

Title "mp3";
Parameters
m(1:3) = [0,1];
p(1:3) = [0,1];
q(1:3) = [0,1];
Variable t,N1,N2,N3;
SharedModel;
Function
N1=(1-exp(-(p1+q1)*t))/(1+(q1/p1)*exp(-(p1+q1)*t))*m1*(1-(if(t<=4,0,(1-exp(-(p1+q1)*(t-4)))/(1+(q1/p1)*exp(-(p1+q1)*(t-4))))));
N2=(if(t<=4,0,(1-exp(-(p2+q2)*(t-4)))/(1+(q2/p2)*exp(-(p2+q2)*(t-4)))))*(m2+(1-exp(-(p2+q2)*t))/(1+(q2/p2)*exp(-(p2+q2)*t))*m1)*(1-(if(t<=6,0,(1-exp(-(p2+q2)*(t-6)))/(1+(q2/p2)*exp(-(p2+q2)*(t-6))))));
N3=(if(t<=6,0,(1-exp(-(p3+q3)*(t-6)))/(1+(q3/p3)*exp(-(p3+q3)*(t-6)))))*(m3+(if(t<=4,0,(1-exp(-(p3+q3)*(t-4)))/(1+(q3/p3)*exp(-(p3+q3)*(t-4)))))*(m2+(1-exp(-(p3+q3)*t))/(1+(q3/p3)*exp(-(p3+q3)*t))*m1));
