摘　　要：1990年6月发射的ROSAT卫星完成了全天的X射线巡天观测，得到了包括18811个X射线源的ROSAT全天巡天亮源表（RASS－BSC）。通过对ROSAT亮X射线源光学对应体的证认，我们已经发现了7个激变变星。给出了这7个激变变星的低色散光谱，并根据它们的光谱特征及其它性质进行了讨论。All-sky X-ray survey has been completed by the ROSAT satellite launched in June 1990, and the RoSAT All Sky Survey - Bright Sources Catalogue (RASS - BSC), which contains 18811 X - ray sources, is published. By identifying the optical objects of the ROSAT bright X - ray sources, 7 cataclysmic variables (CVs) have been discovered. In this paper, the low - dispersion spectrums of the 7 CVs and discuss their spectroscopic and other properties were given.
