摘要
本文根据１９８０年２月至１９８９年１１月期间ＳＭＭ卫星的硬Ｘ射线（ＨＸＲ）暴观测和ＧＯＥＳ卫星的行星际质子积分流量观测，证认出４８个共同样品，统计发现ＨＸＲ暴的寿命Ｔｄ（ｓ）、峰值记数率Ｆｘ（ｃ／ｓ）和爆发期间发射的总光子数ｃ的对数值，与行星际质子积分流量（被归一到耀斑本地）值Ｆｐ的对数值之间，均具有特别显著的线性关系，其中以ｌｏｇＦｐ与ｌｏｇＣ的线性关系为最好，其拟合方程是ｌｏｇＦｐ（＞１０ＭｅＶ）＝一０．６０４＋０．５３８ｌｏｇＣ，相关系数ｒ为０．７０，相对标准误差为０．２８．文中对质子积分流量的预测精度也作了讨论，并给出了置信区间。
In this paper 48 common events of the hard X-ray bursts and interplanetary proton events are analysed statistically.These data are,respectively,from the observations of SMM/HXRBS and GOES satellite.It is found that there are good linear correlations between the logarithmic values of duration Td(s),peak rate Fx(c/s)and total counts c of hard X-ray(HXR) bursts in 25-438 keV and the values of the corrected integral flux Fp(>10 MeV)of interplanetary proton events.Among these correlations,the linear correlation of log Fp and log C is the best.It is log Fp(>10MeV)=-0.604+0.538log C,its correlation coefficient r=0.70.The relative standard error is 0.28.The precision of the integral flux prediction of proton events and their confidence interval are discussed.
