Due to N-N bond weakest, nitrosamines are denitrosated by HBr/HOAc to release nitrogen oxide, which can be oxidized to form NO〓. Trapped in sulphanilamide and N-1naphthylethylene diamine di-HCl solution, the NO〓 transforms into NO〓 and develops color in the solution.

该法根据亚硝基官能团中N-NO键的键能最低，采用氢溴酸/醋酸溶液选择性断裂N-N键，对逸出的NO通过氧化成为NO〓然后用显色剂吸收，再由分光光度计测量吸光度并计算出亚硝胺含量。

2 BJP direct toxicity on TEC NRK52E cell were subcultured on a 24-well plate (3×10〓/ml/well) and exposed to BJP κ or BJP λ in concentration 1, 5, 10, 20mg/ml for up to 24h, then the media was changed, and 〓H-thymidine was added for incubation for 18h at 37℃, the corporation was terminated, Acid-insoluble DNA was precipitated by adding 5% trichloroacetic acid radioactivity in the extracts was determined in scintillation counter.

细胞增殖的影响：将TEC株NRK52E以3×10〓/ml/孔分别加入24孔培养板，分别加入BJPκ与BJPλ（浓度1、5、10、20mg/ml）共同培养，均设3个复孔，24小时后加入〓H-TdR（1μCi/孔）在5%CO〓37℃孵育18小时，终止反应，加胰酶脱壁半小时后移到普通干燥试管，多头细胞收集器抽滤，用5%三氯醋酸，无水乙醇分别冲洗，烤干，冷却后加入闪烁液，放入液体闪烁计数仪测定放射性。

Except cellulose acetate fiber,the strength of other four-kind fibers in completely dry state is decreased notably after MHT.With the initial moisture regain increased,the breaking elongations of cotton,rayon and loycell are improved remarkably after MHT.The increasing level is rayon＞loycell＞cotton,but ramie seems little improved.As the moisture regain is low,the fiber initial modulus is enhanced.However,when the moisture regain is higher,the fiber initial modulus did not change obviously.

除了醋酸纤维素纤维，其余四种纤维在初始回潮率为0的时候，经过微波处理，纤维强度都是显著性下降的：随着初始回潮率的增大，棉纤维、粘胶、天丝的断裂伸长率有了显著性的提高，其中升高的幅度为粘胶＞天丝＞棉纤维，苎麻没有显著性提高；在回潮率较小的范围内，微波处理之后纤维的初始模量是增大的，随着回潮率的增大，初始模量变化不显著。

The non-isothermal decomposition kinetics of nylon 1010 and nylon 1010/POSS composites in nitrogen were investigated. POSS significantly increased the activation energy but had little effect on the reaction order.(5) Exploring research was carried out on the reaction between EVM and nylon 1010. The reaction between EVM and TsOH during melt mixing was also invesigated, and related reaction mechanisms were studied in terms of NMR, TGA-FTIR and etc.

五初步研究了乙烯-醋酸乙烯酯橡胶和尼龙1010在高温下的反应性，报道了EVM和TsOH在高温条件下的反应性，通过核磁共振、热重-红外联用等分析表征方法探索了相关的反应机理，EVM和TsOH反应后，EVM的耐溶剂性、玻璃化转变温度和力学性能均有所提高，而体积电阻率则显著下降。

After put the melamine-formaldehyde resin to modify polyvinyl acetate emulsion,the effects of copolymonomer,PVA,emulsifying agent and initiator on emulsion property were viewed.

实验结果表明，改性胶粘剂的耐水性和粘接强度较普通的聚醋酸乙烯乳液有明显提高。

Acetone is also an important basic organic material, being used in the manufacture of methyl methacrylate, bisphenol A, methyl isobutyl ketone, and also in the production of cellulose acetate tablets, solvents for pla,stics and paints, and the solvent dewaxing for petroleum refining. In 2006, the production ability for phenol was 610,000 tons per year in China, the output was 520,000 tons, and the appearance consumption was 752,000 tons.

丙酮也是重要的基本有机原料，它用于制造甲基丙烯酸甲酯、双酚A、甲基异丁基酮等，用于生产醋酸纤维素片、塑料和涂料的溶剂以及石油炼制的脱蜡溶剂。2006年，我国苯酚生产能力61万吨/年，产量52万吨，表观消费量75.2万吨。
