HeliumNonflammableExplosionModel predicting flammability limits at various initial pressures was created.FLs of mixtures with lower H2/O2 ratios are different from LFLs of hydrogen in oxygen or air.Critical concentrations of helium increase with H2/O2 ratio from 0.5 to 2 for mixture at 21°C....
High‐resolution He‐β spectra of heliumlike chromium have been recorded in an effort to provide accurate atomic data useful for the development of diagno... V Decaux,P Beiersdorfer,S Elliott,... - 《Review of Scientific Instruments》 被引量: 25发表: 1995年 PRODUCTION METHOD, AND FILTER CO...
Heat transfer fluid mixtures and methods of making and using same are presented. The inventive heat transfer fluid mixtures consist essentially of at least one light gas, such as hydrogen, and at least one heavy fluid, such as helium wherein the mixture will not be capable of mixing with ...
The resulting sample was purged with helium for twenty minutes, after which the feed gas was switched to hydrogen and allowed to flow for ten minutes before heating to 200°C. The sample was held at 200°C for one hour in H2. It was then allowed to cool in the hydrogen atmosphere ...

is that core-hydrogen burning main-sequence stars and core-helium burning red clump stars have the smallest amount of differential rotation on average. This implies that the presence of a convective core has a direct impact on the efficiency of angular momentum transport within stars across their ...
Food waste, garden cuttings, manure, and even human sewage can be turned into solid biocoal for energy generation, and, if scaled up, could help match the industrial demand for carbon with the need to get rid of organic waste and reduce greenhouse gas em
The resulting solution can be evaporated to dryness at temperatures preferably in the range of from 50° C. to 70° C. under a partial vacuum with an inert gas, such as helium. Additional organic solvent, such as acetonitrile can be added and the evaporation procedure continued. To the ...
