摘要
本文绘出类星体3C286在毫角秒尺度上的一个超分解图象。它是历元1991．45用一个全球VLBI阵在波长18cm观测所得到的结果之一。整个结构延伸～500Pc。在东北端有两个高亮度的子源，它们与喷流一起浸肤于一个巨大的低亮度的发射区之中。没有检测到有反向喷流存在。我们提出了新的模型来解释这种结构形态。
The paper presents a superresolved image of QSO 3C286 0n milli - arcsecond scale. It isone of the results obtained from the observation of the source at λ= 18cm conducted at epoghof 1991. 45 with a global VLBI array. The wh0le length of extension is about 5OOpc. Thereare two bright components located at the north - east end. Both the components and the jetare embeded in a huge emission region with low brightness. The counter jet of 3C286 on PCscale is not found. We explain the morphology with a new model.
