Contrasted with the activity of the same reaction in oil-water double phased system, the hydrolyzing behavior of Camlicla Lipolytica Lipase in reversed micellar systems is much like that in oil-water double phased system. The stability and catalyzing activity are both enhanced and give rise to "superactivity". except in reverse micelles composed of cationic surfactant.

In this study,one pair of specific primer for mature chicken interleukin-18(ChIL-18) cDNA was designed and synthesized according to the previously published gene sequence of ChIL-18.The full length cDNA gene of ChIL-18 encoding mature active protein was amplified from LPS–stimulated MDCC-MSB1 cells by Reverse Transcription-Polymerase Chain Reaction.Then it was cloned into pMD18-T vector. Sequencing analysis showed that the nucleotide sequence of this ChIL-18 mature protein gene was 5l0bp including the stop coden and the same as the published ChIL-18 cDNA sequence by Schneider K.

本研究根据已发表的ChIL-18成熟蛋白(mature ChIL-18，mChIL-18)的cDNA基因序列，设计一对特异性引物，应用反转录-聚合酶链式反应(reverse transcription-polymerase chain reaction，RT-PCR)技术从脂多糖刺激10小时活化的马立克氏病成淋巴细胞样细胞系MDCC-MSB1的cDNA中扩增出编码鸡IL-18成熟活性蛋白的全长基因，对扩增片段进行T-A克隆，经PCR、酶切鉴定及测序验证，成功获得ChIL-18成熟蛋白完整基因的克隆。

The theory of the simulation is that, firstly put fuze and parts in simulation device in reverse, then fire them in high speed by air gun , and they fly into gun spinning quickly and impact cushion and brass block in it , negative acceleration because of impact is to simulate setback , meanwhile they spin with spin gun when impacting, so spin environment can be simulated, so the simulation system can stimulate setback and spin of fuze in fire.

该模拟系统的原理是将引信及其零部件倒置在模拟弹丸中，通过空气炮以高速发射出去，然后飞入高速旋转的旋转管内，与旋转管内的缓冲块和黄铜块碰撞，碰撞而形成的负加速度作为引信发射时受到的后坐，由于碰撞时与旋转管一起旋转，模拟引信发射时的旋转环境，达到模拟引信发射后坐与旋转环境的目的。

Brashly proclaimed that when and if the universe stopped expanding and began to contract, time would reverse and everything that had ever happened would be rerun in reverse.

例如他在1985年草率宣布，如果宇宙停止扩大并开始缩小时，时间就会逆转，凡是发生过的一切事情就会逆时间顺序重演一遍。

Aside from this, Dale Tiffany also presents various items in their product line, cheap dvds , including products that make use of stained glass, reverse-painted glass, Favrile hand blown glass, and many other techniques.

除此之外，也呈现出各种物品蒂尔在其产品线，廉价dvd，包括产品，利用彩色玻璃制成，reverse-painted玻璃吹制玻璃手，Favrile，和许多其他的技巧。

In this case, what we referred to as "reverse writs" would be items that drop from creatures that players hunt.

在这种情况下，就象我们所谈到的& reverse writs&就是指通过猎杀怪物获取掉落物品。

Since Al〓Ga〓In〓P possesses larger valence band difference to GaAs and wider energy gap, minor carrier reverse injection from base and space charge region recombination in the emitter are effectively suppressed in Al〓Ga〓 In〓P/GaAs HBT. Under most circumstances, quasi-neutral base recombination current dominates the base current, and its ratio to collector current varies little with collector current and temperature, thus greatly stabilizes the current gain.

Al〓Ga〓〓In〓P/GaAs HBT由于异质结的△Ev较大，发射区禁带较宽，有力地抑制了基区少子反向注入流和发射区空间电荷区复合电流；在大多数情况下，基极电流以准中性基区复合电流为主，其与集电极电流的比值随集电极电流和温度的变化极小，稳定了电流增益。
