AbstractAll 13 eclipse CVs inside period gap are investigated. Considering that most CVs inside period gap lack the enough data accumulation, We only choose five objects to make orbital period analysis including a prototype polar AM Her and pre-CVs HW Vir. Although AM Her is not an eclipsing CVs, the facts that its orbital period locates in the upper edge of gap and it has a stable timing system suggest that AM Her should be a significant object for the study of period gap. All orbital period analyses for the CVs inside period gap never indicates any secular evolution information, which may suggest that the CVs inside period gap have a different evolution end. Moreover, the complex O-Cs variations can be explained by the light trave-time effect. It means that there are many substellar objects surrounding the CVs.
