正方形格子上逾渗阈值上估计的修正
Revision of upper estimate of percolation threshold on square lattice
摘要：
本文在簇分解的基础上，得到了二次格点${\Bbb Z}^2$上{ \it选址问题}逾渗阈值的更精确的上界估计.它是通过估计有限簇的外边界${\Bbb Z}^2$上的圈数来实现的
英文摘要：
The more exact upper estimate of the percolation threshold for the {\it site problem} on the quadratic lattice ${\Bbb Z}^2$ have been found on the basis of the cluster decomposition. It is done by the number estimate of cycles on ${\Bbb Z}^2$ which maybe external boundaries of finite clusters
