为筹建新的世界绝对重力基准网(IAGBN),国际大地测量协会(IAG)于1985年6月20日至7月10日在法国巴黎举行了国际绝对重力仪比测。在此期间,IAG的三个特别研究小组:3.87(筹建新的世界绝对重力网)、3.86(绝对重力仪比测)、3.85(相对重力联测)举行了联席会议,讨论了建立IAGBN网的有关技术问题。 目前世界上掌握绝对重力测量技术并拥有绝对重力仪的中、美、苏、法、意五个国家的六台仪器参加了比测。涉及3.85、3.87特别研究小组的联邦德国、日本、奥地利、美国、意大利等国家的专家学者共
In preparation for the establishment of the new IAGBN, IAG held the International Absolute Gravimeter Test from June 20 to July 10, 1985 in Paris, France. In the meantime, IAG’s three special study groups: 3.87 (Building a New World Absolute Gravity Network), 3.86 (Absolute Gravimeter Test), 3.85 (Relative Gravity Joint Test) held a joint meeting to discuss the establishment of the IAGBN network Related technical issues. At present, six instruments in five countries of China, the United States, the Soviet Union, France, France and Italy, which possess absolute gravimetry and absolute gravimeter, have participated in the ratio test.
