Hi xiaoliang:
Firstly, I think you need to decide what kind of model you want to fit. Base on your data, I guess maybe you can use logarithm X coordinate (Double click the axis and select Log10 type under Sclae tab) and fit a sigmoidal curve. Please read:
Analysis: Curve Fitting > Nonlinear Curve Fitting from the Menu > Sigmoidal > Using the Sigmoidal Fit Tool
of Origin Help for more information.
