【摘要】 北京天文台密云观测站(工作频率146兆赫)于1972年8月得到了太阳射电爆发以及同238活动区(McMath 11976)相连系的Ⅰ型源的一些观测结果.本文第一部分,给出了活动区过日面期间米波146兆赫射电爆发的观测结果.第二部分,对观测结果进行了分析,并同与Ⅰ型源相连系的厘米波缓变源的观测结果进行了比较.发现在Ⅰ型源同厘米波缓变源的逐日变化上存在带有约为2天时延的相关.这种演化关系可能是由于低速(～1公里/秒)电子等离子体云所携带的非势磁场的浮升所致.根据Ⅰ型源角径的观测,估计了Ⅰ型源的背景磁场强度.更多还原

【Abstract】 Some results of measurements made in August 1972 of the solar radio bursts and the Type-I source associated with the active region 238 (MeMath 11976) have been obtained at Miyun station, Peking Observatory (working frequency 146 MHz). We describe in the first part of this paper the observations of radio bursts at 146MHz during the period in which the active region moved across the solar disk. In the second part of this paper the results of measurements are analyzed and compared with the associated S-components in centimeter wavelengths. It is found that the daily variations of the Type-I source are correlated with those of the S- components with 2-day time-delay. This evolutionary relation could be a result of emergence of some non-potential magnetic fields imbeded in slowly moving (≈1 km/s.) electronic plasma clouds. From measurements of the angulat extent of Type-I source, strengths of the background magnetic fields are estimated.更多还原
