The research results of this dissertation have the important theoretical and practical significance to safe and efficient mechanized production of china coal mine at present.

In order to find out and analyze it\'s application in Hangzhou,Zhejiang Province,we made an investigation in the mechanized production of rapeseed through it\'s limiting factors,necessities,advantages and countermeasures.

The paper puts forward the mechanization development models and countermeasures for potato production according to the development status of production mechanization,planting characteristic and its technological demand in Guizhou.

Based on investigation, this paper puts forward suggestions for the production mechanization pattern for navel orange in the south of Jiangxi from optimization and combination of ecology, benefit and farm machinery.

To this end,the mechanization of potato production discusses the importance of the development;analysis of the development of our country potato mechanization status quo,the main problems and constraints;on the development of potato production mechanization trend.

Based on analysis of the information management status,goal and functions of the sugarcane mechanization production system,a information management platform was constructed for sugarcane mechanization production system.

Research on quality of punch line based on SPC

Using analytic hierarchy process integrating MATLAB/GUI interface to programme and getting the result of the investment project appraisal by illustrating the appraisal of automotive enterprise′s three projects of punch line′s investment.
