活动双星和dMe型星（猎犬RS型星，dMe型星，大陵五，激变变星，大熊W型星，活动超巨星）；

Active binaries and dMe stars ( RS CVn stars ; dMe stars ; Algol ; cataclysmic variables ; W UMa stars ; active supergiants );

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。

By identifying the optical objects of the ROSAT bright X - ray sources , 7 cataclysmic variables ( CVs ) have been discovered .

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。

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 .

利用PCA降维，大大减少了高维光谱数据的维度空间，然后利用BP人工神经网络进行筛选，提高了激变变星搜寻的准确率，减少了模型训练时间。

By PCA dimension reduction , the high dimensional data space has been greatly reduced , and after that , BP ANN is used to screen out rare celestial objects with high accuracy . In this way , the training time becomes shorter .

对各种方法得到的结果进行时间、类CVs个数等综合分析和比较。比较不同方法筛选出激变变星的候选体，并分析其原因。

Comprehensive analysis and compare the test results obtained on the various methods on time , star-rate , The results obtained on the various methods for time , star-rate , etc. Different methods select its cataclysmic variable star candidates , and analyze the causes .

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。

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 .

该方法不仅对激变变星适用，对于其它类别的特殊天体也是适用的。

The method can be used not only to search the Cataclysmic Variable stars but also to find other types of special objects .

本文从射电、红外、可见光三个波段对激变变星的观测现象，如流量分布、光变曲线、驼峰现象和闪烁现象，以及对这些观测现象的理论解释作一简单介绍。

In this paper , we introduce some observational characteristics about Cataclysmic Variable at the radio , infrared and optical band , such as flux distribution , light curve , hump phenomenon and flickering . We also present some simple theoretical explanations of them .

恒星光谱一般具有明显的吸收线或者吸收带特征，而具有发射线的恒星光谱对应着特殊类型的恒星，如激变变星、HerbigAe/Be等。对这些光谱的后续研究有着重要的意义。

Stellar spectra are characterized by obvious absorption lines or absorption bands , while those with emission lines are usually special stars such as Cataclysmic Variable stars ( CVs ), HerbigAe / Be etc. The further study of this kind of spectra is meaningful .
