| 摘 要： | 我们对周期小于周期分布空缺段的激变变星(CVs),重新进行了周期分布统计,使用了比Warner等人更多、更新的资料.统计中发现一个AM Her型CVs:GRU V1偏离了Warner等人的统计结果.我们给出了CVs 新的周期分布图和相应于此分布的随机概率.虽然结果与Warner等人的不同,但周期分布同磁场仍呈现一定的相关性,磁激变变星(MCVs)与非磁激变变星(NMCVS)同样显示出成团趋势.

| Abstract: | Using more data than Warner et al., we perform statistics on the period distribution of CVs whose period is lower than the orbital period gap. We find thatfor a type AM Her CVs--GRU V1 the period distribution is different from thestatistics of Warner et al. We present new period distribution of CVs and statistical probability. Though the result differs from that of Warner et al., the period distribution appears related with magnet. Both magnetic CVs (MCVs) and the nonmagnetic CVs (NMCVs) show a tendency of clustering. |
