In addition, it is assumable that the electrons returning to Au will cause the degradation of driving force to capture free electrons from TiO2. As a result, the recombination of electron-hole pairs tends to be increased.

另外，苯乙硫醇将电子回传给金时，造成金吸引二氧化钛电子的趋动力下降，减低捕捉二氧化钛自由电子的能力，增加电子电洞对复合的机率。

The enzymolytic products identified were:diisopro-pylaminoethanethiol through the breakdown of P-S bond, and its oxidized product, N, N'-dithiodiethylene-bis ; and diisopropyla-minochloroethane through the breakdown of S-C bond.

VS与电鳐乙酰胆碱酯酶作用的主要产物是： P—S键断裂产物二异丙氨基乙硫醇，该化合物在水溶液中不稳定，可进一步氧化为N，N＇-双二异丙氨基乙基二硫醚；S—C键断裂产物二异丙氨基氯乙烷。

Ethanethiol,thiophene and dibenzothiophene as the model sulfur compounds were analysed by FPD in the gasoline.

选择乙硫醇、噻吩和二苯并噻吩作为汽油中的目标检测硫化物，采用火焰光度检测器进行分析。

In this study, new benzo[l,2,3]thiadiazole derivatives were designed according to relationship of structure and efficacy. The 9 novel compounds were synsthesized with following reactions. The chlorine atom in 2-chloro-3,5-dinitro-benzoic acid as beginning raw material was substituted by 2-methylpropane-2-thiol, esterified then with bromoethane, reduced by iron powder and cyclized to obtain ethyl benzo[l,2,3]thiadiazole-7 after diazonation reation.

本论文根据苯并噻二唑诱导剂的构效关系设计了新的苯并噻二唑的结构，并合成了9个未见文献报道的化合物，合成步骤如下：采用2-氯-3，5-二硝基苯甲酸为起始原料，苯环上的氯原子被叔丁基硫醇置换，羧酸由溴乙烷酯化，硝基由铁粉还原，随后经重氮化关环生成苯并[1，2，3]噻二唑-7-羧酸乙酯。

The polymer particles were prepared by copolymerization of phthalic aldehyde, allyl mercaptan and ethylene glycol dimethacrylate after heating. The fluorescence intensity of the polymer particles was very weak.

利用邻苯二甲醛与烯丙基硫醇、乙二醇二甲基丙烯酸酯在偶氮二异丁腈引发下热聚合制得了一种新型聚合物颗粒。

AFt was extracted from cement paste containing sulphur - fixed ash using glycol and methanol (mixing ratio =1:3) as solvent, and its content was measured by back titration method.

选用1：3乙二醇-甲醇溶剂以相当高的选择性从掺固硫渣的水泥水化浆体中萃取钙矾石并采用返滴定法测定其含量。
