摘要

The object of the experiment was to test the recirculating device of the standard U.S. Navy helium-oxygen deep sea diving helmet and to determine the vacuum,high pressure nozzle flow,total recirculation and pressure drop of air,oxygen and HeO2mixture of about 19.5% O2in a HeO2recirculating system under various depths.
