Through the flow simulation and layout analysis of pre-positioned tail cutter of the crawler minitype sugarcane harvester,reasonable locations are confirmed for the harrow wheel,the conveying roller,the feeding roller,the leave stripper and the exporting roller.

The style design, layout analysis, medias selection and control design of the interface are discussed, which is focused in the amiability and the facility by considering the request of the user.

A Global Analysis Method Based on Interpolation and Point Mapping;

When n =0, the global analysis are made to the quadratic systems (Ⅱ) δ=0 with the origin O (0,0) as second order fine focus.

A numerical global analysis method for nonlinear dynamical systems—Cellurated Integration Method—isproposed in this paper.

In this paper a three- dimensional global analysis of heat transfer by considering unsteady three-dimensional melt flow was developed,and the effect of unsteady three-dimensional melt flow was discussed.

This paper intends to give the methods of principal components analysis for the instant planar data and global principal components analysis for the multidimensional dynamic data system in the environmental evaluation,especially focuses on the synthesis and simplification of the sequential solid datasheet,then gets the satisfied result in the examination.

Based on designing evaluation index system,this paper puts global principal components analysis to the related evaluation data of six provinces in central China area from 1997 to 2006,uses of cluster analysis to classify,and contrastively analyzes mutative law on land intensive utilization in central China area.
