Zhang编码
2)  Zhang-Zhang polynomials
Zhang-Zhang多项式
1.
In this paper,we give an explicit recurrence expression for the Zhang-Zhang polynomials of the cyclo-polyphenacenes and determine their Clar numbers,numbers of Kekul(?) structures and their first Herndon numbers;And we also give an upper bound of anti-forcing number of the cyclo-polyphenacenes.
记h(C)为Clar覆盖C中六角形的个数,σ(H)=Max{h(C)|C为H的一个Clar覆盖},我们称多项式P(H,w)=sum from i=0 toσ(H)σ(H,i)w~i为Zhang-Zhang多项式,其中σ(H,i)表示H中含有i个六角形的Clar覆盖的个数,w为未定元或H中与六角形有关的权。
