摘      要：§1 Introduction In [1], we have discussed the asymptotic behavior and structure of solutions of the linear delay differential equation (1.1) (r0 is a real constant), and have obtained the following result: If p(t)=const., or p(t)0 and integral from n=t to t+r(p(s)ds≥1) , then any solution x(t) of (1.1) can be expressed as
