对西藏冈底斯带南部雄村铜金矿床的容矿火山岩和外围岩石进行了岩石学、地球化学、锆石年代学研究。

In this work we exploited both these approaches simultaneously by forming composites with polyvinyl alcohol, zirconium phosphate and cesium salt of silicotungstic acid.

在本研究中我们通过与聚乙烯醇，磷酸锆，和硅钨酸的铈盐形成复合物，同时探索了这两种方法。

The results show that the zirconium sol has good spinnability when n: n= 1:3, reaction time is 6h and aging temperature is 15℃. The ZrO_2precursor fibers are made from hydrous zirconia chelated by acetylacetone. The sintercd fibers arecomposed of metastable tetragonal phase and sized about 15μm in diameter. Moreover, there aremany pores inside the fibers, but no cracks.4. ZrO_2/PVP hybrid fibers were prepared by blending the spinnable zirconium sol and 10 wt%PVP solution.
