Knittle et. al. propose perovskite is stable, whereas Mao et. al. consider it will transform to the mixture of magnesiowüstiteO and stishovite due to temprature effect.

例如，Knittle等人认为，钙钛矿型SiO〓是稳定的，在整个下地幔中可保持为单一相态；但Mao等人认为，由于温度的影响，它也可能转变成方镁石O与斯石英SiO〓的混合物相态。

Although multidentate heteroatomic could catalyse high selectivity of α-olefin such as 1-hexene and 1-octene,these ligand usually use expensive co-catalyst such as MAO,so it hardly has broad application in α-olefin field.

但由于多齿杂原子配体一般需由价格相对昂贵的烷基铝氧烷，特别是MAO的活化才可进行高效催化反应，因此长期以来多齿型配体难以得到广泛应用。

Long-chain branched polyethylene was obtained using a homogeneous bianary catalyst system composed of late and early transition metal complexes,namely a mixture of bis(α-naphthalidine)-2,3-butanediimine NiBr2 and Cp* TiCl3,as catalyst precursors in the presence of MAO.

合成了一种后过渡金属镍化合物 [二- N ，N′--2 ，3-丁二亚胺镍二溴化物 ][C10H7—NC(CH3)C(CH3)N—C10H7]NiBr2，此化合物在MAO活化下催化乙烯聚合能得到含有末端双键的低分子量聚乙烯，即长链α-烯烃。

Pray that all these team members "will know God's enabling and fulfillment in their new roles": Meth Kong, part-time short wave coordinator; Yeoun Mao, who will move to Christian programming and also help with audience relations; Roun Keo, full-time IT technician and librarian; and Pagnan Kong, now in program presenting and production.

为以下这些团队同工「在适应新角色时能认识上帝凡事都能，成就一切」祷告：短波配搭兼职同工 Meth Kong 、即将制播基督徒节目并支援听众关系事务的同工 Yeoun Mao 、全职资讯工程师兼图书馆管理员 Roun Keo 以及负责节目呈现及制作的 Pagnan Kong 。

Results:Sorbaria sorbifolia extract significantly increased the activity of SOD in brain tissue, decreased the content MDA, inhibit the MAO activity. It was observed under microscope that Sorbaria sorbifolia could retrieve the degeneration of mitochondrion.

结果：珍珠梅提取物可提高D半乳糖所致大鼠脑组织SOD活性、降低MDA含量，抑制MAO活性；电子显微镜观察到珍珠梅提取物可以减轻D半乳糖导致的线粒体等超微结构的改变。

This thesis adopted an ancient animal model in the experimental research and chose NOS, MDA, MAO-B and Tche that may delegate memory and learning, research Mus' memory and learning at the "excessive fright impairs the kidney" stress.
