Abstract
Using the method proposed by Peng (1988) and analyzing the spiral patt erns, the thicknesses of 70 southern spiral galaxies whose images were taken from the Digitized Sky Survey at Xinglong Observational Station of Beijing Observatory were measured. The spiral arms of all these ga laxies have been fitted on their images with some logarithmic spiral c urves to get their optimum inclinations.
