OBJECTIVE: To analyze the sintering and mechanical properties and microstructure of nano-powder 3 mol % yttria stabilized tetragonal zirconia polycrystal (3Y-TZP).

目的：分析摩尔分数为3%氧化钇稳定的四方多晶氧化锆(3Y-TZP)的烧结性能、力学性能及微观结构。

This study showed that yttria stabilized zirconia can be brazed to 444 stainless steel by in-situ alloying of pure Ni-Ti foils at temperatures around 1000°C. The best brazes were produced when brazing for 60 minutes at 1010°C and 30 minutes at 1030°C.

概要 此文验证了氧化钇稳定的氧化锆在1000°C下可以使用纯镍、钛箔现场配制的合金进行钎焊444不锈钢。1010℃钎焊60分钟，1030℃钎焊30分钟可以达到最好效果。

The fine nanostructure yttria stabilized tetragonal phase zirconia membrane is prepared by sol-gel method and the wetting ability of the ceramic thin film before and after laser ablation is discussed.

应用溶胶-凝胶法制备了纳米量级钇稳定四方相精细氧化锆陶瓷膜，研究了陶瓷膜在一定强度的激光作用下，其表面浸润性的变化情况。

Chemical analysis of zircon crystals reveals whether they formed in the presence of water.

对锆石晶体的化学分析可揭示它们是否在水存在的情况下形成。
