| Abstract: | Authors analyse compolctely timc and space variable phenomenon for geoma-gnetic Z compomcnt of S_q,S_D and 11 year's variable regularity in China,atthe same time lowest point movement and even up phenomenon on the base ofthen.we have obtained lowest point movement and even up phenomenon usualycccur in winter in the observatory of North-China,and they are normal pheno-menon superposed on normal geomagnetic field. |
