1983年8月儿日至13日在西德汉堡举行了第十一届国际重力委员会(简称IGC),IGC会上集中总结、研究了世界各国的精密重力测量及各种重力仪的性能情况,会上布郎什(Boulanger)教授和国际计量局绝对重力仪的研究者佐久间博士全面介绍了各国绝对重力仪在国际计量局(简称BIPM)的比对结果及装置情况。从总结介绍的结果看,参加比对国家的仪器在BIPM比测结果是良好的,所测得的差值 The Eleventh International Gravity Committee (IGC) was held in Hamburg, West Germany from August 1983 to March 13, and the IGC concentrated on the study of precision gravimetry and performance of various gravimeters in various countries in the world. Dr. Boulanger and Dr. Sakura, author of the Absolute Gravimeter of the International Bureau of Measurement, presented the results of comparison and installation of absolute gravimeters at the International Bureau of Weights and Measures (BIPM). From the summary of the results of the introduction, to participate in the comparison of national instruments in the BIPM test results are good, the measured difference
