动态拟稳平差的整体平差方案

提要本文提出了动态拟稳平差的另一种解法,其平差结果与1]导出的方法是一致的,但减少了不少计算量.文中导出了有关计算公式,并给出了附加降G~T和先验权阵P_Y.

SOME DISCUSSIONS ON THE CORRELATION BETWEEN EARTH'S RATATION AND THE EARTHQUAKES

Instudying the time, space and intensity characters of earthquakes compared with earth's rotation, we have found some laws: 1. Annual variation of the seismic activity in China and Europe is consistent with the curre of earth's rotation (a_p); 2. Monthly frequency distribution of global large shocks (M≥8) corresponds to the day length curve (△P) but the curve of frequency is one month in advance; 3. Monthly time-order overlap of the seismic activities (M≥7) is the two hemispheres has a reverse correspondense; 4. The latitudinal distribution of earthquakes shows two seismic heights along N35° and south of equator Changing of the Sun-Earth distance is the main cause the regular seasonal variation of seismic activities.
