中文摘要：

利用新疆天文台南山基地25in射电望远镜在6cm波段对恒星V772Her和βPer进行了偏振观测试验．通过数据处理和校准得到恒星的射电光变曲线．探测到V772Her的射电耀发现象，耀发时的线偏振度约达30％，偏振位置角约4°；探测到βPer的缓变成份及叠加其上的快速耀发，βPer耀发时线偏振很弱．

英文摘要：

The radio continuum and polarization observations of the stars V772 Her and β Per are carried out with the Urumqi 25 m radio telescope at 6 cm band. We use the mapping mode to observe the first calibration source, the pointing mode to observe the second calibration source, and the onoff mode to observe star object. The light curves of stars are obtained after data processing and calibration. We detected a radio flare from star V772 Her on 2011 April β. The linear polarization fraction of this flare is about 30%, and the polarization angle is about 4°. We detected another flare from β Per on 2011 April 13. A possible related weak linear polarization may also be detected. Our observations rank first in detecting the radio flares of stars with the Chinese domestic radio telescope.
