| Abstract: | A new explanation of hybrid model of additional system parameter was presented by thinking of semi-parameter.The method for calculating parameter adjustment was deduced.The estimation of parameter and semi-parameter,the precision assessment formular were obtained.Simulation test verified the validity of semi-parameter estimation and made a further expansion for additional semi-parametric model. |
