We establish the quantum theory of the one-mode micromaser injected by ultracold V-type three-level atoms with atomic coherence, and discuss the properties of the emission probability, the photon statistics, the spectrum and the velocity selection. We find the following results. There are two sets of peaks in the plot of the emission probability versus the cavity length. The injected atomic coherence can deeply affect the values of the two sets of peaks and the unresonant platform.

The study about the flux and index of gamma-ray loud blazars show:(1)there is significant correlation between the luminosities in gamma-ray and VLBI radio energy band;(2)there are strong anticorrelarions among the observed indices of soft X-ray, hard X-ray and gamma-ray. For the FSRQs, the whole X-ray emission was contributed by synchrotron self-Compton emission, for the HBLs, the X-ray emission was dominated by synchrotron emission while the soft X-ray emission is dominated by synchrotron emission and the SSC emission dominate the hard X-ray energy band for LBLs;(3) there are strong radio-radio and radio-optical flux correlations for the quasar 3C 273. The higher frequency emission leads those in lower frequency. The multi-band complex indices strongly correlated with the high frequency flux which implies that the object is becoming bright when the energy spectrum is harden.
通过对γ噪Blazar天体的谱指数、流量的相关研究,发现(1)51个样本blazar的γ射线光度与VLBI光度之间存在显著相关;(2)软X、硬X以及γ波段的观测谱指数之间存在较强的反相关,对FSRQs,无论是硬X射线还是软X射线的辐射都是逆康普顿辐射的贡献,而对于HBLs来说,则是同步辐射的贡献,对LBLs,在软X射线波段以同步辐射贡献为主,在硬X射线能区以逆康普顿贡献为主;(3)3C 273的射电各个波段以及光学之间存在强相关,高频辐射一直领先低频辐射,3C 273的多波段复合谱指数和高频流量之间存在强的反相关,意味着当能谱变硬时对象变亮。
