AS expressed the amount of curve profile area of Y phase in the unit containing surface area, S(X). The test methods and formulas were deduced, e.g.: AS=ICI, /IC=LCl /BC. In the formula, ICI and IC indicated the intersection numbers of test line with curve intercepts (or profiles in 2D) and with the containing curve respectively. BC denoted the length of containing curve, LCI, being the length of curve intercepts. The formula means that AS are equal to the curve intercept density and equal to the curve profile intersection density in surface. Issues about AS applicationand its correction for shrinking tissues were discussed. Example for testing AS was givenTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaDruštvo za stereologijo in kvantitativno analizo slike
