He(helium)
1.Conclusions: The changing tendencies of vital capacity and its components ERV and IC after breathing He-O2 containing 60% helium are consistent with those after breathing He-O2 containing 80% helium, and their changing rates are also similar, which indicate that He-O2 containing 60% helium may has the same therapeutic effect as that containing 80% helium does in clinic.
3.Results: After breathing He-O2 containing 60% helium, VC and ERV increased enormously, while IC decreased mildly, among which the change of ERV showed significant difference (P<0.05).
6.In this paper, the helium and argon isotopes of groundwater in Hebei plain are analyzed. According to "excess helium" (4He exc) 3He/4He ratios,δ3He value, 38Ar/36Ar and 40Ar/36Ar ratios, the helium and argon isotopes of groundwater in Hebei plain show seven characteristics: ①The concentrations of "excess helium" in groundwater increase in the flow direction of groundwater.
7.Performance Investigation on Liquid-Helium Temperature Two-Stage Pulse Tube Cryocooler with ～3He/～4He as Working Fluid
9.Gas reservoir with -3.35‰ of 6 13CCO2 (PDB) , 3.20 of 3He/4He ratio and 4.43 of R/Ra ratio is recongnized inorganic origin with much mixed Helium from mantle orgin. COi gas reservoir in Gaoqing area is kept in structure and lithology trap.
10.Helium-charged Al films are prepared by direct current (DC) magnetron sputtering with a He/Ar mixture.
