【摘要】 本文对W·K·Chen提出的用集合基本补划分的概念,通过分解,无重复地产生全部树的方法作了扼要的介绍,然后着重提出一个产生集合的全部基本补划分的新方法,我们取名为“组合比较法”。该法简单、直观,有规律性,而且完全可以用观察法正确地写出全部基本补划分,因此,可以做为W·K·Chen提出的确定基本补划分算法的补充和改进。更多还原

【Abstract】 This paper illustrates briefly the concept of the essentialcomplementary partitions of a set proposed by W. K. Chen.The concept enablesto generate all of trees without duplication through docomposing the networkunder consideration.Then a new method is given for accomplishing it.It isnamed "Combination and Comparison method",by which all essential comple-mentary partitions can be found systematically by inspoction and it issimpler and easier of observation than Chen’s algorithm, so it may beconsidered as a supplement to and improvement of the latter one.更多还原
