本文詳細地介紹了武汉采用的交点相关法和十点相关法的理論基础和具体計算方法,并与Philtips和spcncer的相关法(PS法)及Yerg的六点相关法进行了比較。正如理論上所預期到的,武汉的实驗表明:交点法提供的参量最多,也最精确可靠,但計算量与PS法的差不多;十点法提供的参量与交点法的一样多,精确性不此PS法的低,然而計算量比PS法的少得多,与六点法的差不多。文中还討論了利用时移图上曲直线,以进一步提高十点法的精确性,以及在相关分析中采用結构函数和后效函数,以进一步簡化計算的可能性。本文还初步討論了各种相关分析法的誤差間題;并提出了相关函数值在时空上的預报方法,以及根据相关函数的預报值与实測值的对此等,判别在記录分析中有无反常現象,和甄別所求出的参量值是否可疑的方法。最后还特別指出了电离层混乱运动变化速度出現虛数值的可能性,并介紹了消除这种虛数值的方法。
This paper introduces in detail the theoretical basis and specific calculation methods of the intersection-related and ten-point correlation methods used in Wuhan, and compares them with the correlation between Philtips and spcncer (PS) and Yerg’s six-point correlation. As theoretically expected, experiments in Wuhan show that the intersection point method provides the most parameters, the most accurate and reliable, but the computational cost is almost the same as that of the PS method. The ten-point method provides as many parameters as the intersection method, and the accuracy is not This PS method is low, however, the computational complexity is much less than the PS method, almost the same as the six-point method. The article also discusses the use of time-shifted curves on the curve, to further improve the accuracy of the ten-point method, as well as the use of structural analysis and post-correlation function in the correlation analysis to further simplify the calculation possibilities. In this paper, the error problems of various correlation analysis methods are also discussed preliminarily. The prediction method of correlation function values in time and space is proposed, and based on the correlation function between the predicted values and the measured values, Analysis of whether there is any anomaly, and the screening method to determine the value of the parameter is suspicious. Finally, the possibility of the occurrence of an imaginary value of the rate of change of the ionospheric chaotic motion is also pointed out, and the method of eliminating this imaginary value is introduced.
