For the needs of researches and predictions of flare activities in the middle-term(101 - 102days), the first thing is that we should establish a suitable form describing flare activities.We have found that the daily flare indices I/ published by NOAA deviate seriously from the normal distribution. Through conversion, we obtained the logarithmic flar indices FL corresponding to the order of magnitude of integral radiant intensity from flaresand found that in this case the normal distribution holds good for FL. Consequently, their mean FL and standard deviation σF in any period of time can perfectly statistically describe the level of flare activity in that period.According to the probability theory, using the random number generator, we deduced the approximate values of FL below the thresholds of reporting, and composed the complete alignment FL(t), which describes the continual changes of solar flare activities.We have calculated FL and σF of every cycle of the solar rotation cycles from 1642 to 1684 and found them to evolve correlatively with the slowly varying component of the Sun (solar flux S0 at 2800 Me). The compound correlation coefficient RF = 0.93, and Rσ = 0.46. On the other hand, the relative regressionresiduals . Evidently, it is difficult to explain and forecast them quantitatively, and we should further explore the law.In addition, we have also found that the correlation coefficint of FL with Sa equals 0.93 and the corresponding regression equation isFL = -0.70 + 0.0155Sa By relying on the forecasts of the mean Sa of the Solar flux at 2800Mc, we cancomparatively accurately forecast the average FL of the logarithmic flare indices,

鉴于中等时间尺度(10~1—10~2天)耀斑活动研究和预报的需要,首先应确立恰当的描写耀斑活动的方式。 我们发现,美国国家海洋和大气管理局发表的每天耀斑指数I_f,严重偏离正态分布。我们经变换得到对数耀斑指数(它对应于耀斑辐射积分通量的量级) 遵从正态分布,其时段平均值F_L和标准差σ_F便可完备地统计描写该时段的耀斑活动水平。 依据概率论,利用随机数发生器,我们推求了低于报导阈的F_L近似值,构成F_L的完整的时间序列,描写了耀斑活动的连续变化。 我们计算了1642—1684太阳自转周每周的F_L和σ_F。发现它们与太阳缓变成分(2800兆赫射电流量S_a)相关演变,复相关系数R_F=0.93,R_σ=0.46;另一方面,F_L的相对回归余差仍近20%,σ_F的相对回归余差则近30%;定量地予以解释和预报,显然是需要探索的艰巨任务。 另外,我们发现,F_L和S_a单相关系数r=0.93,回归方程 F_L=-0.70+0.0155S_a 凭借2800兆赫射电流量平均值S_a的预报,便可预报对数耀斑指数较为准确的平均值F_L。

The radio telescope (PEKG 9395) of Beijing Observatory at 3.2 cm began to practice the absolute calibration and daily relative measurement of solar flux density in 1965. A pyramidal horn used as a standard antenna for measuring gain of the paraboloid antenna used in daily calibration was designed. The size of the horn is 36.1 cm ×29.1 cm ×240 cm. As a standard noise power a hot noise source boiling water was developed. The effect temperature that the hot noise source supply is about 373 K. The rms. error is ±0.24 K.The gain of the paraboloid antenna with diameter of 2m used in daily calibration was obtained by the method to measure the solar emission using the horn antenna and paraboloid antenna in turn. The experiment arrangment is shown in Fig, 2. The experiment was carried out repeatedly in 1965, 1968, 1969, and 1978. The results were consistent and are shown in table 1. T.(h), the distribution of the background noise temperature of the paraboloid antenna directing at zenith and meridian plane, were calibrated by the hot noise source and has been taken as "second noise standard" of daily calibration. The results are shown in table 2, and Fig. 3. The total error is about 3.6% (rms)-8% (max).The mean ratio of the solar flux density in a year between PEKG 9395 and TYKW 9400 (Toyokawa Observatory,Nagaya Univ., Toyokawa, Japan) is different from one unity by a factor of 0.02 (shown in table 3 and Fig. 4). After analysing the data it was found that the annual veriation of the ratio of solar flux density between PEKG 9395 and TYKW 9400 are caused by the annual variation of Ts(h), the distribution of the background noise temperature of the paraboloid antenna, and the correct factor of atmospheric attenuation. The annual variation of the ratio was almost removed by means of modifying the background radiation by measuring daily with a gas discharge noise tube and correcting the atmospheric attenuation (shown in Fig. 5 and Pig. 6).The accidental error of daily calibration make a few progress in late years, but it was found that the accidental error raised as the solar activity increase, because more intense active regions that cause the observed value decreasing and more bursts of GRF, PBI type that cause the observed value increasing appeared in max. Years.Through observation for one and half solar cycle, it is proved that our absolute calibration and daily relative calibration have a fine absolute accuracy and a good stability of short and long term. This method may be used in all centimeter band and long millimeter band.
