These papers aim to investigate the distribute of rfde with delays and the asymptotic behavior of its solutions
本文就時滯微分系統特徵根的分佈及其解的漸近行為作了一些研究，並得出了一些結論。 -
A brief description of the organization of this paper follows. there are four chapters in this paper. in the first chapter, by using the character of operator d and liapunov functional, we deal with the stability of solutions of linear nfde of d - operator type with infinite delay, generalize the results of rfde
基於這類方程的復雜性，可以討論具體的volterra方程。本論文共分四章。第一章利用d運算元的性質及liapunov泛函討論了無窮時滯d運算元型fde的穩定性，推廣了一般泛函微分方程的結論。 -
Fde and dde have been extensively developed since 1959, and each branch has been set up a complete theory system. now, more and more scholars study fde and explore further developments. also, fde with infinite delay is one of the fields of great interest to people. in fact, fde with infinite delay has undergone a rapid development since 1870s. hale and kato gave a normal and set up the b phase space theory in 1978. under the basic theory, people studied the stability, boundedness and periodic solution of rfde. for example : in [ 4 ], huang qichang introduced the concept of uniformly forgetful functional, discussed the boundedness and stability of solution ; [ 5 ] - [ 8 ] discussed the existence of periodic solutions, generalized the results of rfde with finite delay. however, for nfde with infinite delay, few people discuss it, and many problems have not been solved. so there are some very interesting developments. lt is worth while generalizing the results of fde with fini te delay or rfde with infinite delay to nfde with infinite delay. because of the difficulty of infinite delay, we may discuss neutral volterra integro - differential equations, and obtain simple results
自1959年以來，無論是一般的泛函微分方程還是具體的微分差分方程，其發展是非常迅速的，在每一分支中都形成了一套完整的理論體系，如今越來越多的學者涉足這一領域探求更新的發展，無窮時滯泛函微分方程就是他們研究的主要對象之一。準確地說，無窮時滯泛函微分方程興起於19世紀七十年代， 1978年hale與kato提出b空間的公理體系。在此體系下建立了方程的基本理論，並研究了解的穩定性、有界性、周期解等問題，如[ 4 ]利用一致健忘的liapunov泛函討論了解的有界性和穩定性， [ 5 ] - [ 8 ]討論了周期解的存在性，推廣了有限時滯的相關結果。
