开发海洋是人类在２１世纪面临的重大课题。中国六千米无缆自治水下机器人应用技术经过几年实践证明，在这一尖端科技领域中已达国际先进水平，引起世界科技界的瞩目。６０００米海底对人类来说是一个神秘的空间。比航天更为困难的是，６０００ｍ海底的压力高达６００个大气压 The development of the sea is a major issue that mankind is facing in the 21st century. After years of practice, the application technology of autonomous underwater vehicles of 6,000 meters in China has proved that it has reached the international advanced level in this advanced science and technology field and attracted the attention of the world’s science and technology circles. 6000 meters sea is a mysterious space for humans. More difficult than aerospace, the pressure of 6000m seafloor is as high as 600 atmospheres
