摘　　要：本文简要地介绍了发生于２５４５ＭＨｚ和２６４５ＭＨｚ频率上的一次与白光耀斑共生的微波射电大爆发。该爆发有很高的峰值流量，很高的偏振度和很复杂的偏振状态的变化．同时该爆发的第一主峰期间同时观测到色球层白光耀斑连续辐射。本文还简要地讨论了这次射电爆发与色球白光耀斑的时间演化关系及射电爆发在主峰期间偏振状态急剧变化的原因。In this paper,an intense microwave burst associated with a white light flare at 2545 and 2645 MHz on June 6,1991 is briefly reported.The burst had very intense flux density,very high polarization degree,and very complex changes of polarization senses.And in the phase of the first peak of the burst,a chromospheric white light flare was observed.In addition,the time relationship between the microwave burst and the white light flare,and the violent changes of the polarization senses during the peak phase of the microwave burst were briefly discussed.
