【摘要】 本文考察了1967—1972年期间46个较大的0级以上的质子事件与所对应的8800MHz的太阳微波爆发之间的统计关系。 研究表明,将射电爆发按总持续时间T进行分类后,可以在不同的持续时间范围内分别找到同太阳质子流强度紧密相关的射电爆发参数(相关系数为0.83—0.91)。应用这些爆发参数得出的警报方案,预报质子流强度的误差范围为半级或一级(S—S分级法)时,报准率可达70％-94％,虚报率为52％。 此外,统计的结果还表明,Croom提出的平均持续时间T_M并不和质子流强度N_p相关,至少在此波长上不能用来预报质子流强度。更多还原

【Abstract】 The statistical relationship between the 46 comparatively large proton events of magnitude≥O during 1967-1972, and the solar microwave bursts, is investigated in this paper.The investigation shows that, after the classification of the radio bursts by the total duration time T, the radio burst parameters, closely associated with the strengths of the solar proton flux, may be found in various duration time r’anges respectively (the correlation coefficients are0.83-0.91). Applying the alarm program obtained from these burst parameters to the prediction of proton flux with, the error ranges of 0.5-1 magnititudes(s-s classification , the rate of correct prediction may be 70-94%, that of false prediction is about 52%.Besides, the statisticsl results also show that, the average duration time Tm proposed by Groom is not correlated with the strength of proton flux N, and it cannot be used to predict the strength of proton flux at this wave length at least.更多还原
