Origin Ver. and Service Release (Select Help-->About Origin):OriginPro 2021b (64-bit)
9.8.5.201 (学习版)

Operating System: Win 10
有两个问题请问：（1）对origin里面现有的公式进行改造，参数初始化应该如何修改？例如我将y = (a1/(a1-a2))*(exp(-a2*x) - exp(-a1*x))改为y = (φa1*a2/(a1-a2))*(exp(-a2*x) - exp(-a1*x))
（2），其中ε（t）= [(a1/(a1-a2))*(exp(-a2*t) - exp(-a1*t))]/(1 - exp(-a1*t))，这样的公式应该如何自己编辑？
