摘　　要：本文对射电望远镜天线增益Ｇ的几种主要实测方法：包括用标准角锥嗽叭增益理论值的“过渡法”和用已知流量的射电源作校准源的“射电天文法”进行了综述和评价。The measurement methods for the antenna gain of radio telescope are summarized in this paper. The “transition method” with theoretical gain of a standard cone horn and the “radio astronomy methed”using radio sources with given flux as calibrators are presented. Based on these methods the calibration result and accuracy of the ant enna gain are also given for the radio telescope at Yunnan Observatory.
