So this kind of compounds is a research focus in herbicide discovery and development. Based on the photosynthesis center D1 protein structure model of high plant Pisum Sativum, we rationally designed and modified the branch chains of cyanoacrylates in order to improve their herbicidal activity.

本论文根据已建立的高等植物豌豆光合作用中心D1蛋白模型结构和前期工作经验，运用生物合理设计方法，对其中抑制希尔反应活性最好的一类化合物—氰基丙烯酸酯类除草剂的若干侧链进行修饰，以期得到抑制活性较好的化合物。

Through replacing copper Tri-fluoroacetate by copper α-methacrylic in Metal Organic Deposition process, the total amount of fluorine in YBCO precursor solution was reduced by about 50%. As a result, the calcination period for YBCO precurse film was dramatically reduced.

在金属有机盐沉积法制备YBCO薄膜的工艺中，采用无F的α甲基丙烯酸铜取代原来的三氟乙酸铜，可以降低前驱溶液中大约50%的氟含量。

PUA Training is a unique university for students who want to better their lives with women.

聚氨酯丙烯酸酯的培训是一个独特的大学的学生谁想要改善自己的生活与妇女。

Two sorts of polyacrylate derivates were designed and systhesized. One has benzoic acid groups linked to backbone via an alkyl chain of different length, the other has pyridyl groups at its side chain. On the basis of hydrogen-bonding between carboxyl and pyridyl groups, multilayer film was fabricated in mixed solvents. We studied the effect of either the composition of mixed solvents or length of alkyl chain on the structure of a multilayer film.

设计合成了两类聚丙烯酸酯类高分子，一种侧链含有通过不同个数的亚甲基和主链相连的苯甲酸基团，另一种侧链含有吡啶基团，基于羧基和吡啶基之间的氢键相互作用，在混合溶剂中制备了多层膜，并研究了溶剂组成与高分子侧链间隔基长度对多层膜结构的影响。
