The preferred (111) orientation of MgO films became better with the increase of the annealing temperature or thickness of the film. The oxidation of Si surface during the pyrolysis and crystallization of Mg alkoxide is suggested to account for the preferred (111) orientated MgO films on Si (100) and Si (111) substrates.

同时，退火温度的升高和薄膜厚度的增加都能使MgO(111)的择优取向性越来越好；Si的易氧化是导致镁醇盐经过高温分解结晶形成MgO(111)择优取向的主要原因。

Homogeneous catalytic oxidations of organic substrates such as alkane and alkene catalyzed by m-oxo-bismetalloporphyrins and flexible alkoxyl oxygen linked-bismetalloporphyrins were introduced,and the catalytic mechanism of these two bismetalloporphyrins,along with the possible synergetic catalysis mechanism of binuclear central metal were discussed.

主要介绍了μ-氧代双核金属卟啉和以柔韧烷氧链相连的双核金属卟啉作为仿酶催化剂在均相催化烷烃、烯烃等有机底物氧化方面的研究进展，并对这两类双核金属卟啉的催化机理、金属双核的协同催化作用机理作了论述，最后展望了双核金属卟啉仿酶催化剂的研究前景。

Although allene oxide synthase and hydroperoxide lyase are atypical cytochrome P450 family members involved in the synthesis of jasmonates and GLVs, respectively, it is unknown how these enzymes rearrange their hydroperoxide substrates into different products.

这些酶是两种物质的综合体，包括allene氧化物（allene oxide synthase，简称AOS）和过氧化氢酶（hydroperoxide lyase ，简称HPL），它能产生茉莉酸味和一种绿叶中含有的挥发物GLV，后者决定了蔬菜和水果的芳香特点。

Because these substrates are synthesized from the corresponding allylic alcohols, palladium-catalyzed conversion of allylic alcohols directly into allylation products are highly desirable, especially from the viewpoint of the atom economy.

因为这些受质是从烯丙醇合成的，钯催化烯丙醇转换直接变成烯丙基化合物从原子经济的观点来看是较有益处的。

The result indicated that the AlTiN multilayer coating deposited on high speed steel substrates with alternated nitrogen contents in layers. In each layer, AlTiN exhibited nanocomposites of nanocrystallites embedded into amorphous matrices despite of the nitrogen content. The difference between bilayers was that AlTiN layer with lower nitrogen content had a lower density of nanocrystallites. The AlCN coating deposited on Si (100) substrate appeared a strained layer on substrate in the ilm-substrate interface, which thickness was 3～5 atom layer.

结果表明：在高速钢基体上制备的AlTiN多层薄膜由两种氮含量交替变化的膜层构成，尽管交替的两层中氮含量不同，但每一单层都为纳米晶包含在非晶点阵中的纳米复合结构，不同之处是低氮含量层中纳米晶密度较小；生长在单晶硅基体(100)晶面上的非晶AlCN薄膜，在膜基界面处硅基体上出现应力畸变层，应力畸变层厚度很薄，约3～5个原子层。
