The invention aims at improving the quality of flour to researche a method for preparing new flour modifying agent, namely, the microencapsulation glucose oxidase, chitose-calcium alginate-glucose oxidase microcapsule which is obtained through the method is copolymer hydrogel which is obtained through double cross-linking, both amidogen and carboxyl group are fixed, and the whole system is a reticular formation.

本发明以改善面粉品质为目的，研究一种新型面粉改良剂――微胶囊化葡萄糖氧化酶的制备方法，采用上述方法制得的壳聚糖-海藻酸钙-葡萄糖氧化酶微胶囊，是经双重交联得到的共聚凝胶，氨基和羧基均被固定，整个体系为网状结构。

In this research, we used a sol-gel process to prepare UV-curable antiglare coatings. First the inorganic monomer tetraethoxylsilane was formed into colloidal silica by hydrolysis and condensation reactions. Then, added the couple agent 3- propyl methacrylate and surfactant fluoroalkylsilane (13F) to modify the colloidal silica. Finally, organic monomer dipentaerythritol hexaacrylate were added to form hybrid material.

中文摘要本研究是经由溶胶凝胶制程，将无机单体四乙氧基矽烷先行水解、缩合反应成为二氧化矽，接著分别加入偶合剂三异丙基矽基丙烯酸酯、氟化矽氧烷(13F)、对二氧化矽微粒进行表面改质；之后再导入交联剂DPHA加以强化合成出奈米混成涂料。

Methods We used the Kamistad Gel as control manufactured by Germany STADA Pharmaceutical Factory and analyzed the curative effects,paregoric effects and side effects of Benzocaine Paste.
