For the models by MMFI is a nonlinear differential equation with variable coefficients and the 'nonlinearity' brings discommodiousness to analyse the nature and quantification of a control system, it applies brim linearization method to better MMFI. By transforming 'triangle wave' membership functions of the base elements into 'rectangle wave' membership functions, we get three models which represent different aspect respectively. By simulating second order system and analysing the errors of the results, a conclusion is drawn, that is, the model obtained by brim linearization method has a good precision in contrast with the real model.

The antimicrobial test and researched was done on wide distillation of different solvents on Terpenoid, polarity separation of ethanol distillable substance, thin layer chromatography of different polarities and distillation of amylase. The results showed that the active substance distilled by 95% ethanol and V methanol: toluene=3:1 had stronger antimicrobial activity on Agaricus blazei Murrill. The antimicrobial activity of ethyl acetate was stronger than wide distilling substance with ethanol, but the water part has not antimicrobial effect. Two straps of ethyl acetate phase(Rf0.57、Rf0.63)(0.1g/ml)had stronger antimicrobial activity on Agaricus blazei Murrill, the antimicrobial zone on Pseudomonas was 19.3mm. The bacteriostatic activity of chromatography strap of water phase was rather weaker, the water solution (0.5g/g) of amylase had better effect on pathogenic fungus of Agaricus blazei Murrill, its antimicrobial zone on Aspergillus niger, Citrinin, Trichoderma viride were 10.8 mm, 7.9 mm, 5.3 mm.

During using anaerobic fermentation slurry as insecticide, there had many problems that are random using, non-strictly prevention and curing time, non-suitable temperature and consistency mixture ratio ctc. In this research, fristly the different mixtures are made according to the different ratio of slurry to additive. Then the insecticidal effects of the mixture are tested in different conditions so as to find the good matches of slurry and additive in laboratory. According to the up result of the good matches extents of mixture, the field experiment is made to test the mixture's insecticidal chraricter and is further found new dosage form which has many good indexes such as good insecticidal effectiveness, little additive dosis ctc. So as to looking for the dosage form's synergism, the significant analysis is done and the characters of the dosages are tested which are ecological and environmental and the new types of dosage are determined. At last, for proving the dosage's field insecticidal potency, the wide field area experiments are done and four new style dosages are triturated which adapt ecological agriculture development. Aadditionally the effective period of the mixtures are tested when other experiments are done.

The chemical weathering index, K/Na ratio, eluvial coefficientand A-CN-K diagram , can availably indicate the evolution of pedogenic environment. The A-CN-K and CIA-K/Na diagram showed that the Holocene paleosol was in the primary stage of weathering, which K-feldspar went through weak weathering and K was less leached with much leach of Ca and Na. The intensity of weathering went stronger gradually from west to east in the Weihe Valley.
