摘　　要：本文研究了两类重要微分不等式有界解的性质。引入了赋范线性空间(f,‖‖M),利用比较定理和黎卡提方程解的性质,给出了有界解的上界估计式,推广和改进了文[1,2]中的有关结果.In this paper we study properties of bounded solutions for two important differential inequalities. We introduce the linear normed space （f.｜｜ ｜｜M）and obtain estimates for their bounded solutions by using comparison theorm and properties of solutions for the Riccati equation. The results improve and extend the related resdts in.
