With the aeciospore wall of armandii pine blister rust as inducer, chitinase gene was induced to express in Trichoderma atroviride cells. The cDNA fragment of chitinase gene was cloned by RT-PCR approach.

方法］采用华山松疱锈病的锈孢子壁作为诱导物，诱导深绿木霉SS003中几丁质酶基因的表达，并通过RT-PCR方法扩增得到几丁质酶基因片段。

The meat of them has been transmuted in the alembic of Martin Eden's mind and poured into 'The Shame of the Sun,' and one day Martin Eden will be famous, and not the least of his fame will rest upon that work.

那些书的精华已经被马丁·伊登提炼吸收，注入了《太阳的耻辱》。有一天马丁·伊甸会成名，而那部著作对他的名气的作用决不会小。

Catalytic effect of ionic liquids to isobutane and butene alkylate reaction was studied,composition of ionic liquids,isobutane and butene mole compares factors to the alkylate reaction influence was reviewed.

研究了离子液体对异丁烷与正丁烯烷基化反应的催化作用，考察了离子液体组成、异丁烷与正丁烯物质的量比等因素对烷基化反应的影响。

During the reaction of alkylation, general contained 0.2%~2.0% butadiene will produce viscous heavy composite materials, which will raise final boiling point of alkylate and decrease octane, what is more, it will react with acid to produce corresponding ester, which will increase the consumption of acid, Therefore, we must remove butadiene by selective hydrogenation, at the same time, it will convert some of 1- butane to 2- butane by isomerization and raise octane of alkylate.

一般含有0.2%~2.0%的丁二烯，其在烷基化反应中，可生成一种分子量很高的粘稠重质迭合物，使烷基化油的干点升高，辛烷值降低，并且它还和酸反应生成相应的酯而加大酸耗量。因此必须经过选择性加氢除掉丁二烯，同时，将部分1-丁烯异构化为2-丁烯，以提高烷基化油的辛烷值。

In their structures, polyanions are bridged by Ln ions via the coordination of the bridging oxygen atoms and terminal oxygen atoms, forming a W–Ot′–Ln–Ob–W linkage; and through the W–Ot′–Ln–Ob–W linkage a one-dimension infinite linear chain with alternating cations and anions is formed.

在相似的合成条件下，我们向原有体系内加入顺丁烯二酸作为有机配体，合成了化合物7，其7的基本结构和化合物1-6很相似，但有一个顺丁烯二酸阴离子取代了一个NO3-离子的位置。
