本文介绍了爱因斯坦天文台对33个星系的X射线观测结果。几乎所有这些星系，其中一些位于团体和互动对，显示干扰形态。没有统一的、定义明确的选择标准可以描述样本星系，但几乎所有的样本星系都位于光学色/色图的一个区域，这表明它们正在经历星星形成的爆发。这个区域与马卡良星系的轨迹是一致的。给出了观测样品和X射线数据，讨论了X射线数据，并与星系的光学和射电性质进行了比较。它的结论是，核活动是不是晚型奇特星系的X射线的主要来源，X射线辐射很可能是源于人口I星系的组成部分，特别是二进制源和可能的年轻SNR的。
The results of X-ray observations with the Einstein Observatory of 33 galaxies are presented. Almost all of these galaxies, some of which lie in groups and in interactive pairs, display disturbed morphologies. No uniform, well-defined selection criterion can describe the sample galaxies, but almost all lie in a region of the optical color/color diagram that suggests that they are experiencing bursts of star formation. This region is compatible with the locus of Markarian galaxies. The observed sample and the X-ray data are presented, and the X-ray data are discussed and compared with the optical and radio properties of the galaxies. It is concluded that nuclear activity is not the predominant source of X-rays in late-type peculiar galaxies and that the X-ray emission is likely to originate from the Population I galactic component, in particular binary sources and possible young SNR's.
