Abstract:

The cashmere morphological structure including the cashmere diameter，the scale height and the percent of the scale ring are measured with an optics microscope for the cashmere in Ali. The distributions for the cashmere diameter with the scale height, the cashmere diameter with the percent of scale ring, the cashmere scale height with the percent of scale ring are showed respectively. The proper linear fittings are determined on the least squares method and the correlation coefficients are also computed among cashmere morphological structure. It shows that there is a larger positive correlation between the cashmere diameter and the scale height while the correlations between the percent of scale ring with the cashmere diameter and the scale height respectively are smaller negative ,. The similar correlations among cashmere morphological structure are also found in the cashmere from Alashan and Gaixian respectively. The average correlation coefficient between the cashmere diameter and the scale height is 0.5414，the average correlation coefficients between the percent of scale ring, the cashmere diameter and the scale height are -0.2288 and -0.2170 respectively from above three areas.

Key words: cashmere, morphological structure, correlation, distrebution, linear fitting
