已知自变量t，因变量y，y和t满足一下函数式：

dy/dt=0.001414/(1/(4.5727*10^4*k1*(1-0.02119*y)^k2)+1/k3/45727)；（需要指出的是，该公式中参数可进一步合并，在本帖中并未作合并处理）

已知 t=；y=；拟合出参数k1，k2，k3。-Known independent variable t, the dependent variable y, y, and t satisfy my functional: dy/dt = 0.001414/(1/(4.5727* 10 ^ 4* k1* (1-0.02119* y) ^ k2)+1/k3/45727)　(It should be noted that the equation parameters can be further consolidated in this post are not treated as a merger) is known t =　y =　fitting parameters k1, k2, k3.
