A refinement of Ramsey theorem(Ramsey定理的一种推广)
Zhejiang Daxue xuebao. Lixue ban, 2002 Ramsey定理指出:对于任何一个正整数k,存在一个最小的正整数r(k,k),使得对任意一个至少有r(k,k)个顶点的图G,它或者有k个顶点的完全子图Kk,或者有k个顶点是独立集.由此定理易得:设G是顶点数n>r(k,k)的简单图,其边数e>0,且G的所有k阶导出子图的边数相等,那么G是完全图.并给出上述结论的推广:设G是n(n≥4)阶简单图,其边数e>0,对某个给定的自然数k(2≤k≤n-2),若G的所有k阶导出子图的边数相等,则G是完全图.

Function minimization with fixed polarity based on K map(基于K图的函数RM展开式在固定极性下的最小化)
Zhejiang Daxue xuebao. Lixue ban, 2003 分析了K图的性质,发现在K图中过某格的所有聚合圈相应的各乘积项所含变量与该格对应的最小项均有相同的极性,在此基础上提出了得到基于K图函数RM展开式在固定极性下的最小化的图形方法.该方法可以从K图直接得到函数的最小化的RM展开式,从而省略了传统的把K图转变为bj图再求最小化的步骤.它具有直观、简单、易于掌握等特点.此外,文中还提出了该方法的改进算法.
