开发了一种方法来确定在由没有间隙或重叠的凸多边形单元组成的图案中单元边界收缩了多少;当给定单元图案时，可以制作另一种图案，其总边界长度变得比原始的短，而不减少每个单元的面积。通过重复这样的过程，可以预测边界长度接近最短可能长度的假设蜂窝图案，并且可以估计s值;指示蜂窝图案的边界缩短的缺乏程度。该方法适用于几个细胞和人工模式;培养的上皮细胞在单层鸡肺和鸡视网膜色素，丁香叶表皮，二维排列的肥皂泡等。结果进行了讨论，在最近的知识收缩微丝有组织的细胞。
A method was developed to determine how much the cell boundary contracts in a pattern consisting of convex polygonal cells with no gaps or overlaps; when a cellular pattern is given, another pattern can be made whose total boundary length becomes shorter than the original, without reducing the area of each cell. By repetition of such procedure, the hypothetical cellular pattern whose boundary length has approximated the shortest possible length can be predicted and the s value can be estimated; an indication of the degree of lack of boundary shortening of the cellular pattern. The method is applied to several cellular and artificial patterns; cultured epithelial cells in monolayers from chick lung and chick retina pigment, epidermis of Syringa leaf, 2-dimensional arrangement of soap bubbles, etc. The results are discussed in relation to recent knowledge on contractile microfilaments in organized cells.
