摘要
讨论了方程anx(n) (t) +an - 1x(n - 1) (t) +… +a0 x(t) +bx(t -τ) =eαttk 的解的一些表达式 。
This paper deals with the expressions of solution to the differential equation, i.e.a nx (n) (t)+a n-1 x (n-1) (t)+...+a 0x(t)+bx(t-τ)=e αt t k .Some general results which has been shown by paper as a particulan example.
