3.Based on the questions in current document retrieval course,the importance of integration of information literacy education and document retrieval course is pointed out,the integrated design scheme based on integration designing model put forward by L.Dee Fink is suggested,and the questions needed to be noticed are discussed in this article.
4.Finally, by applying nonlinear functional method and the exponential dichotomy theory, the sufficient conditions of the existence on almost periodic solutions for forced Lienard-type equations are proved, which are the natural extension of the results already obtained by Fink et, al, in particular, a computational error of Fink in SIAM.
