Our solutions conclude that V921 Her is an early type marginal contact binary system with an additional close-in component. The binary system is under poor thermal contact with a temperature difference of nearly 700 K between the two components. The close-in component contributes about 19% of the total luminosity in the triple system. Combining the radial velocity study together with our photometric solutions, the mass of the primary star and secondary one is calculated to be m 1 = 1.784 （ ± 0.055 ） m ⊙ 那 m 2 = 0.403 （ ± 0.012 ） m ⊙ 。V921她的演化情况进行了讨论。光最低V921的她在参考书目中可用的所有时间都考虑到与 O. - C. 曲线进行分析的第一次。最可能的拟合结果的文件，这也证实第三组分的存在（讨论 P. 3. = 10.2 年）围绕双星系统。V921的期间她也在经历的速率连续快速增长 D.
