Classical representation is only a particular case of it.Some of the variables affecting the equilibrium atmosphere when trace oxygen ispresent and optimum preparation of the gas mixtures to minimize errors have beendiscussed. The reliability of some of previous equilibrium experiments under theoxygen potentials controlled by H_2O-H_2 or H_2O-H_2-inerts gas mixtures has alsobeen criticized. Key words： gas equilibration method    H_2O-H_2    H_2O-H_2-inerts    oxygen potential 收稿日期: 1989-04-18      基金资助:国家自然科学基金 服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 方正 陈新民 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1989/V25/I4/81 1 Emmett P H, Shultz J F.
