The results suggested that yttria has a more effect on suppressing grain growth and stabilizing tetragonal phase than that of ceria when added at the same amount.

首次提出NH〓Cl在沉淀反应过程中依靠过饱和析出，并包裹在由Zr〓和Y〓共同组成微核上使其相互隔离的微观机制模型，该模型能很好地解释NH〓Cl加入量多少对粉料粒径及团聚状态的影响规律。

The single micronucleus and multi-micronucleus were observed at the interphase. The chromosome aberrational cells including chromosome fragment, lagging chromosome, chromosome bridge and circular chromosome were found during the mitosis. RAPD analysis of seedling genomic DNA variation in M 2 generation of three mutants showed their DNA sequences had changed. The result confirmed that the implantation of 7Li +3 ions could induce genetic mutation in wheat.
