phylla: 金币+50, ★有帮助, 非常感谢您！不过拟合结果的确不行呢。。我再等看看有没有人能帮忙看出方程需要加啥参数。。自己也可能再修改一下方程，到时候可能还要麻烦您了，呵呵 2012-10-26 22:32:12
结果不是很好！
模型公式: y = ((k)^2*(733.9*(x)^0.5+i*(16.514*1.0/(1.0+1.0/(50*(x-4.65)^2+2.314))+1.568*(x-4.65))-1581.5-i*1.637))/((1+(k)^2)*((1581.5+733.92*(x)^0.5)/2+1*i*((1.637+16.514*1.0/(1.0+1.0/(50*(x-4.65)^2+2.314))+1.568*(x-4.65))/2)+(((1581.5-733.92*(x)^0.5+1*i*(1.637-(16.514*1.0/(1.0+1.0/(50*(x-4.65)^2+2.314))+1.568*(x-4.65))))/2)^2+176.09*x)^0.5-1581.5-i*1.637)*((1581.5+733.92*(x)^0.5)/2+1*i*((1.637+16.514*1.0/(1.0+1.0/(50*(x-4.65)^2+2.314))+1.568*(x-4.65))/2)-(((1581.5-733.92*(x)^0.5+1*i*(1.637-(16.514*1.0/(1.0+1.0/(50*(x-4.65)^2+2.314))+1.568*(x-4.65))))/2)^2+176.09*x)^0.5-1581.5-i*1.637))
y = ((-5.88700435557742e-8)^2*(733.9*(x)^0.5+i*(16.514*1.0/(1.0+1.0/(50*(x-4.65)^2+2.314))+1.568*(x-4.65))-1581.5-i*1.637))/(1*((1581.5+733.92*(x)^0.5)/2+1*i*((1.637+16.514*1.0/(1.0+1.0/(50*(x-4.65)^2+2.314))+1.568*(x-4.65))/2)+(((1581.5-733.92*(x)^0.5+1*i*(1.637-(16.514*1.0/(1.0+1.0/(50*(x-4.65)^2+2.314))+1.568*(x-4.65))))/2)^2+176.09*x)^0.5-1581.5-i*1.637)*((1581.5+733.92*(x)^0.5)/2+1*i*((1.637+16.514*1.0/(1.0+1.0/(50*(x-4.65)^2+2.314))+1.568*(x-4.65))/2)-(((1581.5-733.92*(x)^0.5+1*i*(1.637-(16.514*1.0/(1.0+1.0/(50*(x-4.65)^2+2.314))+1.568*(x-4.65))))/2)^2+176.09*x)^0.5-1581.5-i*1.637))
