【Abstract】 Through presenting a reverse evidence,point out the error of a result about classification for nonoscillatory solutions of unstable type functional differential equations in the book of "Oscillation Theory for Functional Diffevential Equations".If p =1,the classification of asymptotic behavior for positive solution of the equation (x(t)-px(t-r))′-q(t)x(g(t))=0, t≥t 0. Where p≥0,r>0,q∈C([t 0,∞),[WTHZ]R +),g∈C([t 0,∞),[WTHZ]R),g(t)≤t, and lim t→∞g(t)=∞ is not right,and modifies the result appropriately.更多还原
