Comparison the influence of environmental factors on two rice brown planthopper biotypes;

Biotype Determination of Ralstonia solanacearum in Chongqing Tobacco Growing Area;

Influence of Various Composing Proportions of Rice Brown Planthopper Biotypes on Resistance of Rice Varieties;

Males and females of the two biotypes placed together in various inter-biotype crosses exhibited courtship behavior, but no copulation occurred,.

The biotypes of several important pests including Mayetiola destructor, Schizaphis graminum, Nilaparvata lugens, Orseolia oryzae and Bemisia tabaci on agricultural crops were introduced, then the applications of molecular markers to the research on biotypes were generalized.

tumefaciens, but penicillin expressed no effects on these two biotypes.

A study of microbiota in irrigated area aroud Zhangye paper mill;

This paper at tempts to analyze and demonstrate the polluted water quality of pulp and paper wastewater from the indication of the microbiota by observing and monitoring the microbiota in the irrigated areas around Zhangye Paper Mill.

The production process of biological briquettes was proposed in the paper with a comparison study of common briquettes and biological briquettes.

The biological model of monolayer anchorage-dependent cell apoptosis induced by in vitro β-ray irradiation is established to dynamically observe the cell apoptosis.

In section 2, we introduce an organizing principle with which to study management methods: the evolution from the mechanical model of management through the biological model to the social model.

This article sums up the concept of biological model method and the type of biological model method,analyzes that the conformity of information technique and biological model method is great important in the process of biological teaching.

In this paper, according to the existing problem of virtual biology model that lacks sense of reality and the constructed model can not satisfy natural biological rule, based on the complexity of the system model and the characteristics of strong alternation and cooperation between various essential factors, this paper proposes a behavioral modeling methods based on fuzzy and evidence theory.
