摘　　要：相接双星物理参数的研究不仅是恒星物理领域的热点课题,也是国际天体物理界非常重视的研究方向,并且我们的课题组在国内已经成功地开展这个领域的研究工作。本文根据从ASAS巡天数据中下载的相接双星数据,利用国际上求解食双星物理参数工具(不断更新的Wilson-Devinney程序)对相接双星的物理参数进行计算,第一次得到ASAS巡天数据中13颗相接双星的物理参数,利用这些物理参数,求解这些相接双星理论值与观测值的光变曲线以及结构图。最后根据获得的这些相接双星物理参数、理论与实测的光变曲线以及结构图,进行分析并得出对应的结论。The study of the physical parameters of the earth is not only a hot issue in the field of stellar physics, but also the research direction of the international astrophysics, and our research group has successfully carried out the research in this field in China. According to the download contact binary data from ASAS survey data, the adjoining binary physical parameters calculation was carried out by using the solving food binary physical parameters of the most famous （constantly updated Wilson-devinney program） tools, for the first time 13 star connected physical parameter of the binary in ASAS survey data were obtained, using these parameters, these binaries theory value and observations of light curves and structure diagram the physical parameters, the theoretical and the measured curves of the were successfully solved. According to binary star, and the structure of the system, the conclusion was drawn and analyzed.
