| Abstract: | Analyses the background value in GM(1,1) model and modifies the method of some references.A new method of background value reconstruction in GM(1,1) Model based on Gauss formula of numerical value integral is pointed out.The new method builds a high precision model for death rate of internal system,nutrition metabolite and immunity disease in our country′s urban areas.The calculating precision of examples show this new method is very effective. |
