Relationship between Coefficients of Variation for Raw Silk Size in Different Testing Length
Electronic inspection criterion of raw silk has been studied in China at present. During this process, we encountered a problem on the relationship between coefficient of variation of short silk segments and mat of long silk segment in electronic inspectinon system. The traditional theory on the testing length and the size variance might cause error in the electronic testing system. In this study, based on the autocorrelation coefficient model of properties of raw silk size time series (i.e. mimetic period and attenuation rate), the error have been analyzed and discussed through a simulation system based on the short silk segments and that of long silk segments. Furthermore, the relationship between testing length and coefficient of variation for raw silk size was determined. We also establish a ratio of the variation coefficients between short silk segments and that of long silk segment. From the above simulation system, the changing law of the ratio dependent on the varying properties of raw silk size was further explored.
