Methyl-2,3,5,6-tetrafluoro-benzene methanol was synthesized by chlorination, acylation, fluorination, esterifica- tion, reduction, bromization, reduction from terephthalic acid. Tefluthrin was obtained from-(1RS,3RS)-3-(2-chloro-3,3,3-trifluoro-1-propenyl)-2,2-dimethyl cycolpropa-necarboxylate acid by reacting with 4-methyl-2,3,5,6-tetrafluoro-benzene methanol.

The article adopted the method of orthogonal design using Polyethylene Glycol and Methacrylic Acid to esterify Polythylene-glycol-mono Methacrylate, then using PMA, MAA and Methacrylic Acid Sulfonic Sodium as raw material to synthesize Polycarboxylic type water-reducer.

用正交实验法研究了聚乙二醇和甲基丙烯酸酯化合成聚乙二醇单甲基丙烯酸酯的合成工艺，以该酯化物与MAA和甲基丙烯酸磺酸钠为原料，在引发剂的作用下合成聚羧酸系减水剂。

The reason why air makes fireburn more intensely was learned only abouttwo hundred years ago, when severalscientists finally proved that oxygen, oneof the gases air contains, can combinewith certain other elements like carbon to release muchheat.

当时某些科学家终于证明，空气中有一种气体叫氧，它能够与其它一些元素化合，从而释放出大量的热。

The reason why air makes fireburn more intensely was learned only abouttwo hundred years ago, when severalscientists finally proved that oxygen, oneof the gases air contains, can combinewith certain other elements like carbon to release muchheat.

参考译文：空气为什么能使火燃烧得更旺？直到大约2 0 0 年前才弄清其原因。当时某些科学家终于证明，空气中有一种气体叫氧，它能够与其它一些元素化合，从而释放出大量的热。

Firstly, Copolymerization of acrylamide and styrene was carried out in a microemulsion system, in which AM aqueous solution was the continue phase and St was the dispersed phase using ST-80 as surfactants respectively, then hydroxamic functions were prepared with hydroxylamine salt at temperatures of from 60℃ to 90℃.

首先以丙烯酰胺水溶液为连续相，以苯乙烯为分散相，ST-80为乳化剂制成微乳液，在15℃~35℃合成丙烯酰胺与苯乙烯的共聚物；然后采用程序控温方式，在60℃~90℃用硫酸羟胺将共聚物羟肟化合成了一种带有苯环结构的嵌段型氧肟酸类聚合物材料。
