摘要
本文推广了共轭点和不共轭微分方程的概念，证明了时滞微分方程的不共轭区间不可能是一个单点集．此外，还证明了时滞微分方程的不共轭性与边值问题的可解性之间的联系．
We generalize the notions of a conjugate point a discojugate equation ,and show that the interval of disconjugacy of each delay differential equation does not degenertae into a one-point set and the show the connection between the disconjugacy of the delay differentiai equation and the solvability of the boundary value problelm.
