In this paper,the detailed semiempirical models representing the chromospheric state during the impulsive phase of the 2B flare on Feb.3,1983 are proposed.The physical pictures of total evolutionary pattern of the impulsive phase of the flare are improved either quantitatively or qualitatively in comparison with the former work we did.Based on these semiempirical models,some dynamical properties and energy processes are also discussed.
