| 1 | 南美SLR监测的2010年智利8.8级大地震产生的地面位移显示文摘2010年2月27日,智利发生了8.8级特大地震,该地震使震中附近的地面产生了较大位移.德国与智利合作的卫星激光测距系统SLR-7405距震中仅约130km,其观测受到地震的影响.中国科学院国家天文台与阿根廷合作的SLR-7406系统距震中约600km,利用这两个SLR站的观测资料并结合全球SLR站的观测资料,在ITRF2000下解算了这两个SLR站点的地心坐标,发现两站的坐标都发生了不同程度的变化.SLR-7405站整体向西南方向发生了较大移动,在X,Y,Z方向上的位移量分别约为3.11,0.52和0.49m,SLR-7406站在3个方向上的位移量分别约为0.02,0.03和0.02m.由SLR这一独立的观测手段得到的结果可以为其他定位观测提供必要的外部检核. | 尹志强 韩延本 PODESTA Ricardo 刘卫东 PACHECO Ana ALONSO Ester ACTIS Eloy 黄东平 赵励民 王锐 夏金超 | 2011 | 科学通报2011，56，2： | 2 |
| 2 | South American SLR stations monitoring ground displacement caused by the M8.8 Chilean earthquake of 2010显示文摘The M8.8 Chilean earthquake of February 27,2010 caused a large surface displacement near its epicenter.Satellite Laser Ranging(SLR) station 7405,cooperatively operated by Germany and Chile about 130 km from the epicenter was affected by the earthquake.Another SLR station,No.7406,operated jointly by the National Astronomical Observatories of the Chinese Academy of Sciences and San Juan University of Argentina,was about 600 km from the epicenter.Combining the observations of these two SLR stations with global SLR station observations,we calculate the geocentric coordinates of the two stations based on ITRF2000.The results show that the coordinates of the two stations have changed by varying degrees.SLR-7405 moved substantially towards the southwest with displacements of about 3.11,0.52 and 0.49 m in X,Y,Z directions;the corresponding displacements for SLR-7406 are about 0.02,0.03 and 0.02 m.This solution,as an independent result derived from SLR observations,could provide an essential external check for other positioning techniques such as GPS. | YIN ZhiQiang HAN YanBen PODESTA Ricardo LIU WeiDong PACHECO Ana ALONSO Ester ACTIS Eloy HUANG DongPing ZHAO LiMin WANG Rui XIA JinChao | 2011 | Chinese Science Bulletin2011，56，8： | 1 |
