欧洲绝对重力仪比对观测(ECGS′07)
|
摘要
介绍了2007年11月在欧洲卢森堡Walferdange举办的第二次绝对重力比对观测的概况及结果.有20台绝对重力仪参加了比对观测,在ECGS共1 5个测点上的比测结果标准偏差小于2.1×10~(-8)m·s~(-2).文章简述了数据处理方法以及结果分析,中国地震局地震研究所引进的FG5/232绝对重力仪参加了本次比对,为在中国大陆建立绝对重力基准提供了重要经验.
The European comparison of absolute gravimeters held in Walferdange,Luxembourg in November 2007 is presented in detail.In total 20 absolute gravimeters were participant and gravity values of 15 stations show the best agreement within a standard deviation less than 2.1 microGal including the FG5/232 of CEA.The method of data processing and results are presented in the article.The comparison provides us much experience for the determination of absolute gravity standards of China.
