摘要
根据对河外射电源3C45.3第二历元327MHZ的MLBI观测数据的多分量模型拟合，得到该源5个分量的模型拟合结构。该结构的尺度从几百毫角秒延伸到几个角秒。与Merlin的观测结果比较，有迹象表明存在一个新的分量C4。
We report a successful multi-component model fitting of the extragalactic radio source3C454. 3 observed at second epoch of 327MHz VLBI observation. Parameters of fivecornponents were obtained. The scale of the structure extends from hundreds mas to severalarcseconds. There is an indication of the existance of a new component C4 in comparison withMerlin observation.
