【Abstract】 Extinction coefficient is a very important parameter in the field of particle sizing technology using optical fluctuation method.But the existing method dealing with it is not perfect.In order to figure out the extinction coefficient curve with some elementary functions directly,we fit it by means of Least Square Method.It simplifies the calculation of the extinction coefficient,meets the engineering measurement requirement,as well as helps to implementing real-time measurement.更多还原
