作为深海探测的重要工具,载人潜水器的研发和研究是衡量各国海洋勘探水平的一个重要标志,“蛟龙”之前,世界上只有美国、法国、俄罗斯和日本拥有深海载人潜水器,它们的最大工作深度均未超过6500米,下潜深度一般只有5000米.中国载人潜水器“蛟龙”号于2012年6月24日在西太平洋的马里亚纳海沟试验海域成功创造了载人深潜新的历史记录,首次突破7000米,最深达到7020米海底。这 As an important tool for deep sea exploration, the research and development of manned submersibles and research is an important symbol of the level of ocean exploration in various countries. Prior to the “dragon,” only the United States, France, Russia and Japan had the world’s deep sea manned submersible, Their maximum working depth are not more than 6500 meters, dive depth is generally only 5000 meters.China manned submersible “dragon” on June 24, 2012 in the Western Pacific Mariana Trench waters successfully created Manned new history of deep dive, the first time exceeded 7000 meters, the deepest reached 7020 meters underwater.
