Analysis of Landscape Design of Green Space of University Students’ Living Area from Environmental Psychology - a Case Study of Chang’an Campus of a University in Xi’an Xin CHEN1, a, Junhua YU2, b 1Department of Architecture, School of Mechanics, Civil Engineering and Architecture, Northwestern Polytechnical University, Xi’an, Shaanxi, 710129, China 2Mail box 52, Chang'an Campus of Northwestern Polytechnical University, Xi’an, Shaanxi, 710129, China acxin36@hotmail.com, byu.junhua@163.com Keywords: Environmental psychology, Students' living area, Green space, Behavior, Psychology.
Inspiration to the Design of Greening Land Based on the investigation and analysis of university students’ behaviors and psychology, we find that reduce the sight interference, emphasize the privacy, and create a quite greening land space is the key to improve students’ satisfaction.
In addition, various format and material could be taken into consideration in designing these seats, which would make Students experience different virtual and touch feeling. 6) To green space between or surrounded by dormitory buildings, it can add its publicity to build roads; reduce interference of sight line to plant high trees; attract more students to go and stay there to provide some simple sports facilities (such as table tennis table, fitness facilities).

corporation, Nanjing 210007, China Email:baifang@nuaa.edu.cn Keyword:six sigma ,management concept, discrete military manufacturing industry Abstract:Discrete military manufacturing industry is analyzed about the characteristics of the product design, processing, manufacturing in this paper, it also discusses the application problem of process management in discrete military manufacturing industry,and has a discussion contrapose on the small sample ,discrete data analysis,the multi-target fusion analysis and processing,the qualitative problems processing method,in order to improve the feasibility and adaptability of "six sigma" in discrete military manufacturing industry. 0.Introduction The market is becoming more and more competitive in current trend,and the quality control has become a inevitable topic,so how to transform “checkout after the things happen” into “prevention before the things happen”,how to reduce the costs effectively while improving the quality of products and engineering
But we could also see many examples of failure when we see the six sigma is springing up in various industries,so how to overcome "not acclimatized" of the new method is the key to success .Therefore,it is necessary to analyze the characteristics of the product design, processing, manufacturing in discrete military manufacturing industry, combinate with the DMAIC model to discuss the application problem of process management of "six sigma", and have a discussion contrapose on the small sample,discrete data analysis,the multi-target fusion analysis and processing,the qualitative problems processing method and so on,in order to improve the feasibility and adaptability of "six sigma" in discrete military manufacturing industry. 1.The characteristics of the discrete military manufacturing industry The product of equipment manufacturing has a certain particularity which is different from the business model with mass production line:firstly,from the nature of the product,most of the products
Firstly definite the output Y that is clear about what we want to be resolved, secondly analyze the influencing factors X,namely by man, machine, material, method,environment，measure and other constraints.This paper discuss the application problem of process management in discrete military manufacturing industry,including reliability, process capability,process quality control points,quality cost and so on
