t-blocking集合的一个新上界

A New Upper Bound of t-Blocking Collection

给出了PG(2,q)上的t-blocking集合的一个一般上界,此上界比以往的上界稍好,同时对知之甚少包含一条线的t-blocking也给出了一个上界.

A general upper bound of t-blocking is given in this paper,and the upper bound is slightly better than the upper bound of the previous,t-blocking while little is known contain a line also gives an upper bound.
