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.

对催化合成维生素A棕榈酸酯反应的脂肪酶和反应介质比较，同时对影响合成维生素A棕榈酸酯反应的因素（温度、初始水含量、底物摩尔比、反应时间和酶量等）进行了探讨，优化了反应条件：在10 mL不含水分的正己烷中，0.200 g 维生素A醋酸酯和0.468 g棕榈酸在酶量为10％（指固定化酶与维生素A醋酸酯的质量比）的固定化脂肪酶催化下，在 30℃、190 r/min下反应6 h，转化率可以达到75%，固定化酶可连续使用6次以上。

The sol-gel silica films on K9 glass substrates were prepared with the dip method, and some of them were treated in saturated ammonia gas.

DC SQUID magnetometers on bicrystal and step edge substrates with both magnetron sputtering and PLD YBCO were fabricated.

在双晶衬底和台阶衬底上，我们用磁控法和PLD法制备的YBCO得到了DC SQUID.I-V曲线较符合RSJ模型。

The good adhesion of the NDFs on silica or optical glass substrates is beneficial for the applications of the NDFs as protective coatings on optical devices and mechanical matings.

石英玻璃和光学玻璃上生长的NDF与衬底间具有较高的结合强度，有利于NDF作为光学器件和机械部件保护膜应用。

The liver is an important organ in the body where various metabolisms of exogenous and endogenous substrates are performed.

肝脏是体内物质代谢的一个重要器官。

The results show that the heavier cold rolling reduction; higher temperature of annealing and a two-step recrystallisation annealing are beneficial to the forming of cube texture in Ni-W substrates.

研究结果表明：Ni-5%W基带是一个比较好的组分，通过大的冷轧形变量、较高的退火温度和两步退火的方式，有利于在Ni-5%W基带中形成单一的、强的立方织构。

The dry toner electrophotography imaging process enables the use of conventional substrates without coating or pre-treatment.
