本文报道了位于Praesepe的WUMa型双星系统TX Cancri的分光、光度和偏振观测结果。确定了系统各组成部分的参数（质量、半径、光度）。如果系统是演化的，那么它必须有足够的质量才能达到目前的状态。我们认为，TX Cnc是未进化的，零年龄接触的二元模型的系统构造。讨论了系统参数和零龄模型的解释问题。
Spectrososopic, photometric, and polarimetric observations of TX Cancri, a W UMa-type binary system in Praesepe, are reported. The parameters (masses, radii, luminosities) of the components of the system are determined. If the system is evolved, then it must have last a substantial amount of mass to reach its present state. We argue that TX Cnc is unevolved, and an age-zero contact- binary model for the system is constructed. Problems in the interpretation of the parameters of the system and the age-zero model are discussed.
