- 化学化工－已发表论文 
The gaseous phase of hydride enrichment techniques have been systematically described in this paper. These enrichment techniques including liquid nitrogen trap, balloon collection, in situ pre-concentration in pre-heated graphite furnace, frapped in absorbing solutions, and in some absorbing solid substances. The principle and the application of these techniques have been discussed detail too. The near future trends of the techniques have reviewed also.
