海洋资源开发和军事作业中,常常需要在超出空气潜水允许的深度采用氦氧混合气进行常规潜水作业。目前,许多国家针对氦氧常规潜水制定了本国的减压表,比较著名的是美国海军和法国Comex公司减压表。我国早期先后引进了前苏联减压表和Comex减压表,随后对这些表进行修订,制定了我国的两种减压表。该文对5种氦氧常规潜水减压表进行比较和分析,为继续优化和新研制安全、高效的减压表进行积累,满足深潜水作业的迫切需求。
In marine resource development and military operations, it is often necessary to use helium-oxygen mixtures for routine diving operations at depths beyond those allowed for air diving. At present, many countries have developed their own decompression watch for helium-oxygen conventional diving, more famous is the United States Navy and the French company Comex decompression table. Early China has introduced the former Soviet Union decompression table and Comex decompression table, followed by the revision of these tables, the development of our two decompression table. In this paper, five kinds of helium-oxygen routine diving decompression table were compared and analyzed, in order to continue to optimize and newly developed safe and efficient vacuum table to accumulate to meet the urgent needs of deep diving operations.
