本文给出了H·Kühr和G·Schmidt汇编的北方射电明亮的BLLac天体的完整样本的射电源的多频偏振VLA观测结果。这些被用来确定18个源的综合旋转测量，其中15个以前从未测量过，这阻碍了对完整样品中物体的内在偏振特性的分析。这些测量使我们有可能对观测到的这些源的线偏振方向进行法拉第旋转效应的校正。在这些天体中，法拉第自转最可能的起源是银河系星际介质。结果给出了完整的BLLac天体样本中所有34个源的综合自转测量结果。
We present the results of multi-frequency polarization VLA observations of radio sources from the complete sample of northern, radio-bright BL Lac objects compiled by H. Kühr and G. Schmidt. These were used to determine the integrated rotation measures of 18 sources, 15 of which had never been measured previously, which hindered analysis of the intrinsic polarization properties of objects in the complete sample. These measurements make it possible to correct the observed orientations of the linear polarizations of these sources for the effect of Faraday rotation. The most probable origin for Faraday rotation in these objects is the Galactic interstellar medium. The results presented complete measurements of the integrated rotation measures for all 34 sources in the complete sample of BL Lac objects.
