By grey relational analysis, the mechanical properties that influence the crease resistance of fabric are linearity of loadextension curve (LT), compressionthickness curve (LC), tensile resilience (RT), compression resilience (RC), shear stiffness (G), coefficient of friction (MIU), thickness (T) and weight (W).
Meanwhile this thesis introduces the Grey System Theory (Grey System Theory hereafter refers to as GST) into the evaluation of enterprise competitive ability based on absorbing the research results of the predecessor. The theory that the thesis applies mainly is Grey Relational Analysis (Grey Relational Analysis hereafter refers to as GRA).
同时在吸收前人研究成果的基础上,将灰色系统理论(Grey System Theory以下简称GST)引入到企业竞争力评价之中,本文应用的主要是灰色关联分析(Grey Relational Analysis以下简称GRA)。
In this thesis we primarily discuss the characteristics, sorts, and research methods of grey relational analysis theory, and also the characteristics of information hiding of image in DWT domain, and thereby successfully apply the grey model to the information hiding technology.
Factors of effecting corn seed production in 7 main provinces were investigated and analyzed with grey relational analysis. The orders of factors of effecting corn seed production total yield and total area were found that the rate of price of seed to grain last year was more important than seed price last year,the later more important than grain price last year.
The article analyzes scientific and technological innovation of large and middle-scale enterprises in China by grey relational analysis through studying the data bank of 1995～2001,from which we attain the grey relational degree among the main invest factors and innovation products.
This paper Propose to make assessment of water qualiby by Grey relationalanalysis.The environment of water body iS regarded as a Grey system,the state variables of the system are Grey variables and the classification of water guality is a Grey Class,thus the uncertainty of classification of water quality is considered.After example analysis,the results is satistactory.
