根据中国—比利时固体潮合作研究协定,比利时皇家天文台基础天文学部范隆贝克(Van Ruymbeke)于1980年3月20日至26日与我国家地震局兰州地震研究所合作开展了固体潮研究工作。在兰州开展中、比双方重力仪固体潮联合对比观测,是中、比重力固体潮合作研究协议计划的重要组成部分。这个合作研究协议的主要内容是:1.从1979年9月到1980年9月,中、比双方重力仪分别在武汉、广州、北京、 According to the China-Belgium Agreement on Solid Tide Cooperative Research, Van Ruymbeke, Department of Basic Astronomy, Royal Observatory, Belgium, conducted a study on solid tides in cooperation with the Lanzhou Seismological Institute of China’s Seismological Bureau from March 20 to March 26, 1980. In Lanzhou, the comparison between the gravity tide and the tide of solid tides is an important part of the agreement on the research of gravity and solid tide cooperation. The main contents of the cooperative research agreement are as follows: 1. From September 1979 to September 1980, the gravimetric instruments of the two countries were compared in Wuhan, Guangzhou, Beijing,
