The present paper deals with the relations of resultant matrices and resultant polynomials with solving the greatest common factor of two - variable polynomials, respectively, on the basis of the concepts of resultant minimum polynomials and standard resultant - base - solving - matrix introduced from the properties of resultant matrices and resultant polynomials
摘要應用結矩陣和結多項式的性質，通過引入結最小多項式和標準結基解矩陣等概念，探討結矩陣、結多項式與求解二元多項式最大公因式的關系。 -
The data matrix for the 37 taxon contained 553 variable sites ( 57. 6 % ), of which 336 were phylogenetically informative. the phylogenetic relationships were inferred using the neighbor - joining and maximum - parsimony methods. in mp method, the heuristic search generated two single most parmonious tree
雙蓋藏屬diplazium 、菜蔽屬c公刀ipteris 、短腸蔗屬allantodia和腸獲屬diplaziopsis構成單系起源，在兩種系統樹中分別得到98 % （ mp ）和100 % （ nj ）的支持率。 -
Third, controlling chaos in the chaotic n - scroll chua ' s circuit is studied. the approach taken is to use feedback of a single state variable in a simple pd ( proportional and differential ) format. first, the unstable fixed points in the n - scroll chua ' s circuit are classified into two different types according to the characteristics of the eigenvalues of the linearized system matrix at the fixed points
第三，研究了多渦卷chua電路中不動點處jacobian矩陣特徵根的性質，並據此將不動點分成兩類，應用變量的比例微分反饋法分別對這兩類不動點的可控性進行了研究，研究發現該法只能實現第一類不動點及其相應子空間的混沌控制，而不能完成第二類不動點的混沌控制，並給出了數值模擬結果，理論分析和數值模擬證實了該方法的有效性。 -
