【Abstract】 The accuracy of GM(1,2) model established in the light of the regular method was lower and its fitting error was bigger. Based on it, it was put forward that the object function was established with the aim of the least absolute value of the fitting error, it was calculated through the optimum design applying the Matlab, and the Grey optimum GM(1,2) model that was applied to quickly determining the moisture regain of the ramie fabric in different optimum schemes was established. At the same time, aiming at the fitting error, the best optimum model was given through the contrast analysis of model in varying optimum schemes The model could be conveniently applied to working out the real value when the moisture of the ramie fabric was quickly determined with a resistant -measuring instrument.更多还原
