| 英文摘要 | Cataclysmic variables are special celestial bodies because they have particular light curves and spectra. The mechanisms for generating emission lines radiated from dwarf novae in their quiescent phases are studied. We assume that the incident radiation field which is emitted by a hot source (white dwarf and boundary layer) irradiates the gaseous layer evaporated from the accretion disk, and the emission lines are radiated from the gas. We model the fluxes of emission lines by using the photoionization code CLOUDY. Using this method, we input some reasonable parameters and get a series of simulated spectra. In order to find a simulated spectrum which is the best fit to an observed spectrum, we use a cross-correlation method to match them. After the calculation, we use the approximation that the parameters of the simulated spectrum can simulate the observed spectrum. Finally, we learn more about the physical conditions of the system. |
