In the software, some functions are realized as follows: the automatic drawing of accident tree,qualitative analysis,automatic resolution of minimal cutset,automatic drawing of equivalent tree,resolution of structure importance degree and incidence of top accident,quantitative analysis of probability importance degree and critical importance degree and finding the m.

A remote-sensing image coding algorithm based on significant coefficients lifting;

In this paper, a new algorithm based on the significant coefficients of DWT is proposed.

This paper makes researches on identification important coefficients in China s discharge of industrial wastewater in 2002 based on the losing information method.

The critical twist factors of two sorts of soybean protein yarn made from different manufacture means are tested and analyzed,the corresponding regression equation,regression curve and the maximum of regression curve are concluded.

To investigate the relationship between strength and the critical twist factor of rotor-spun yarn,yarns made of cotton,polyester and newdal were tensile-tested,then the curve of twist factor coefficient and strength,regression equation and critical twist factor of yarns.
