各位高手，请给予指点谢谢。
微分方程为：dy/dt=k*(10369.5090113348*(0.0000275408670931059-0.000372031696283281*y)*((1-y)/y)^(1.73049210075848)-((1-y)/y)^(-1.73049210075848)/(10369.5090113348*(0.0000275408670931059-0.000372031696283281*y))),初始条件是t=0,y=0。
实验数据为：x=0,1,2,3,5,7,10,15,20,30,40,60,90,115,150,180;y=0,0.038938914,0.041673318,0.04740156,0.056777571,0.057785158,0.059937519,0.061988845,0.066638769,0.067898262,0.068946995,0.067252273,0.067750121,0.068162701,0.068251684,0.06897329;
哪位高手能给些指点吗？自己做了很长时间也没做出来。非常感激。
