英文摘要	Near Contact Binary (NCB) is a kind of close binary in which both components fill or nearly fill their critical Roche Lobes. They are not in contact like W UMa systems, and show EB-type light variations. These characters make the NCB an interesting object. They are important observational targets which may be lying in key evolutionary states. According to the geometric definition of this subclass, NCBs actually comprise semi-detached with primary filling (SDI) or secondary filling (SD2), marginal-contact (C), and marginal-detached (D) systems. We have observed a group of NCBs (e.g. BL and, GW Tau, AS Ser, UU Lyn, RU UMi, GSC3658-0076 etc.) and constructed an evolutionary sequence of case A mass transfer in observation. Finally, the available orbital period variations and absolute parameters of NCBs are collected and the preliminary statistical results are presented.
