一、引言自1939年国际地磁和天电协会建议在实践中使用K指数、定量测定太阳微粒辐射对地磁活动的影响以来,K指数一直作为描述均一的连续的或突发的、瞬时的太阳微粒辐射的地球效应提供着日地之间关系的主要信息。其重要性仅次于地磁台站观测报告中的时均值,并且日益成为地磁记录中定量描述的一个内容,补充于台站的观测报告中。在实践中发展起来的K指数测量技术,一开始就遇到识别非K效应和K效应定量化之
I. INTRODUCTION Since 1939, the International Geomagnetism and Electro-Electronic Society has recommended the use of the K-index in practice to quantify the effect of solar particle radiation on geomagnetic activity since the K-index has been used as a continuous or sudden, instantaneous solar particle describing homogeneity The earth effect of radiation provides the main message of the relationship between the earth and the earth. Its importance is second only to the time-averaged value of the geomagnetic station observations and is increasingly becoming a quantitative description of geomagnetic records, supplemented in station observations. The K-index measurement technique developed in practice encounters quantitative non-K and K effects from the very beginning
