在海洋工程作业、深海打捞等大深度潜水过程中,常采用一定氧浓度的氦氧混和气作为潜水员的呼吸气。众所周知,氦气资源在地壳中的含量极其稀少,而全球储存量80%的氦气在美国。随着电子集成技术的飞速发展,大量氦气应用到集成电路等电子产品生产中,导致氦气的消耗日益增大,氦气枯竭的趋势更加紧迫。上世纪中叶,世界各国都在大力发展氢氧潜水,法国在氢氧潜水领域走在世界的前列,1988年,法国Comex公司在海上做过534 m氢氧饱和潜水试验[1]。我国
In marine engineering operations, deep-sea salvage and other deep diving process, often using a certain oxygen concentration of helium-oxygen mixture as a diver’s breathing gas. It is well-known that helium resources are extremely rare in the earth’s crust, with about 80% of the world’s helium stored in the United States. With the rapid development of electronic integration technology, a large amount of helium is applied to the production of electronic products such as integrated circuits, which leads to the increase of helium consumption and the more urgent need of helium depletion. In the middle of the last century, all countries in the world are vigorously developing the diving of oxygen and oxygen. France is at the forefront of the world in hydrogen and oxygen diving. In 1988, France’s Comex Company conducted a 534 m hydrogen-oxygen saturation diving test at sea [1]. My country
