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。

There are no sufficient holes to follow the negative AC bias stress when high frequency is chosen. Due to the operation of the flat panel displays is under AC signal, therefore we discuss the degradation under DC and AC bias stress which include positive and negative bias stress on gate and drain of TFTs. What's more, we discuss asynchronous gate and drain bias stress on TFTs, and study the degradation mechanisms.

因为实际面板在运作时就是闸极与汲极采用交流方式操作，所以接著探讨在闸极上与汲极上给予直流正、负偏压与交流正、负偏压应力测试，来比较非晶矽薄膜电晶体在闸极与汲极分别有偏压下，电晶体的最大衰退变化量，再加上闸极与汲极给予非同步偏压的状况，探讨此一非同步状况对於电晶体的影响，以及了解是哪些机制造成如此差异。

Novozym 435 was used for the synthesis of vitamin A plamitate. The influences of solvent, the molar ratio of substrates, the reaction temperature and time, and the water concentration were optimized and the best result was obtained by interesterification from 0.200 g vitamin A acetate and 0.468 g palmitic acid, at 30℃, in 10 mL hexane, containing 0% of water, with 10% of lipase(mass ratio, immobilized lipase to vitamin A plamitate). In these conditions, 75% of vitamin A acetate was converted into vitamin A plamitate. The immobilized lipase was reused about 6 batches.
