| 摘 要： | 本文给出类星体3C286在λ18厘米的MERLIN图像、VLBI图像和MERLIN＋VLBI图像．呈现在MERLIN图像上的低亮度的结构在MERLIN VLBI联合阵的图像上基本被分解，仅留下一些支离破碎的痕迹．MERLIN＋VLBI图像的中央部分比VLBI图像有更长的延伸．MERLIN＋VLBI图像的动态范围好于1000：1，但没有搜索到反向喷流．我们提出了几种可能的模式对所得到的结构进行解释．

| Abstract: | The MERLIN, VLBI and MERLIN VLBI images of QSO 3C286 at wavelength 18cm are presented in this paper. The structures with low brightness in the MERLIN image are just resolved in the MERLIN VLBI image. But some vestiges still remain. The extension of the central part of the MERUN VLBI image is longer than that of the VLBI image. Though the dynamic range of the MERLIN VLBI image is better than 1000: 1, the counter jet of 3C286 is not found. Several models have been usedto interpret the structures in the images. |
