For developing an immunoassay for multiple residues of pyrethroid pesticides, the hapten N-2- carbanmoyl-(3"-phenoxyphenyl) methyl 3-(2"-Cldoro-3",3",3"-trifluoropropenyl)-2, 2-dimethylcyclopropane- carboxylate was synthesized from cyanohydrin and 3-(2"-Chloro-3",3",3- trifluoropropenyl)-2, 2-dimethylcyclopropanecarboxylic acid via hydrolysis and esterification. The synthesis of the hapten was foundation of preparaing anti- cyhalothrin polyclonal antibodies.

为了制备对单一拟除虫菊酯高特异性的抗体，以菊酸和氰醇为起始原料，通过水解、酯化反应合成了半抗原N-2-氨甲酰-(3-苯氧基苄基)甲基-3-(2-氯-3，3，3-三氟丙烯基)-2，2-二甲基环丙烷羧酸酯，为进一步制备抗三氟氰菊酯的特异性抗体奠定基础。

Poly/melamine cyanurate composite latex particles are prepared via soapless emulsion polymerization. XPS data and TGA analysis reveal that MC particles are encapsulated by PMMA during polymerization, resulting in the formation of a core-shell structure of PMMA/MC composite latex particles. MC can affect the thermal degradation and promote the charring of PMMA. The application of PMMA/MC in nylon 6 (PA6) indicate that the composite latex particles can improve the mechanical pro...

采用原位乳液聚合法制备了聚甲基丙烯酸甲酯/三聚氰胺氰尿酸盐复合胶粒，对其进行X光电子能谱及热重分析结果显示，在MC阻燃剂颗粒表面覆盖了一层PMMA胶膜，形成了具有核-壳结构的PMMA/MC复合胶粒；MC能影响PMMA的热降解过程并促进其成炭；在尼龙6(PA6)中的应用结果表明，PMMA/MC复合胶粒能改善PA6的力学性能和阻燃性能。

The laser beam emitted by the laser is expanded to the cutting width required by the tipping paper via the laser beam expanding system, the expanded laser beam passes through the cylindrical surface focusing mirror and 4 focuses on the focal plane form a focal line and the tipping paper is cut off by the focal line on the focal plane.

由激光器发出的激光束经激光扩束系统将激光束扩大至水松纸所需的切割宽度，经扩束后的激光束通过柱面聚焦镜，在焦平面4聚焦形成一条聚焦线，水松纸在焦平面上被此条激光聚焦线割断。
