Shear wave splitting is studied based on the digital waveforms of three seismic stations DJS, SZD and WUJ, which were set up after the Jiujiang-Ruichang MS5.7 earthquake of November 26, 2005 around the epicenter area....Shear wave splitting is studied based on the digital waveforms of three seismic stations DJS, SZD and WUJ, which were set up after the Jiujiang-Ruichang MS5.7 earthquake of November 26, 2005 around the epicenter area. The result shows that the time delays of slow shear waves of the DJS station, which is not far from the epicenter and where the distribution of faults is complex near the station, are relatively larger and the polarization directions of fast shear waves are not concentrated; the predominant polarization direction of fast shear waves of WUJ station, with single fault distributed nearby, has a difference of 35° to the strike of the fault and is inconsistent with the direction of regional principal compressive stress. The predominant polarization direction of fast shear waves of SZD station with no faults nearby is in accordance with regional principal compressive stress. There is no obvious regular relationshipship between the delay time and the focal depth.展开更多

It is based on multiparty cooperation and political consultation under the leadership of the CPC. There are at present nine political parties in China. They are, in addition to the CPC, the Revolutionary Committee of the Chinese Kuomintang established in 1948, the Chinese Democratic League founded in 1941, the China National Democratic Construction Association founded in 1945, the China Association for Promoting Democracy established in 1945, the Chinese Peasants' and Workers' Demo- cratic Party established in 1930, the China Zhi Gong Party founded in 1925, the Jiu San Society established in 1945 and the Taiwan Democratie Self-Government League established in 1947.展开更多
