The valenceofelementyttrium of Y2 O3 Mocathode materialhasbeenstudied by usingther mal weight analysis, X ray diffraction analysis, Scanning electron microscopy and X rayphotoelectronspectrum . It hasbeen provedthatyttrium oxidecan bereduced by molybdenum carbide. Thereaction between powdered Y2 O3 and Mo2 Ccan happen at 1173 , and Y2 O3may bereduced to metallicyttrium . Afterthepowder mixtureof Y2 O3 and Mo2 Cwasheat treated at1873 K, Yttrium existsin two kinds of chemicalstate- yttrium of zero valence and yttrium ofthreevalences.

一、有惊无险,基本上实现了软着陆 1995年有两件事一度引起人们的心理恐慌。一是经济增长率连续两个季度滑坡。先是从1994年4季度的5.1％降到1995年1季度的2.7％,接着又在2季度
稠油已成为近几年主要的采油后备资源。最稠的原油分布在东欧及中国西部。在1000～2000m的深度范围内原油黏度最大,随着埋深的增大,原油黏度降低。原油黏度还与含油层的年代有
