The results show that the optimum technology is as follows: hemachrome, sodium nitrite and vitamin C should be mixed in hemoglobin solution as the mol ratio of 1∶3∶12, heating temperature is 85℃, and holding time is 15min. The chromogenic rate of the nitrosohemoglobin prepared under this condition is 90.42%.

结果表明，其最佳制备工艺为：血红蛋白溶液中所含血红素∶亚硝酸钠∶维生素C的摩尔比为1∶3∶12，加热温度为85℃，保温时间为15 min，所得半干固体亚硝基血红蛋白的发色率为90.42%。

The application of energetic addition N, N1-dinitropiperazine in the smokeless propellant is introduced in this paper.

本文介绍了含能添加剂二硝基哌嗪在无烟推进剂中应用的情况。

According to the result, we believed that the reason resulted in the low sensitivity was that the marker residue compound MQCA structure has changed after conjugated with protein and the antibody induced by the conjugation could not recognize the free MQCA in the ci-ELISA. Therefore we designed some hapten which could reserve the marker residue structural speciality mostly. After synthesis route selection and optimum, the hapten 7-Hydroxymethyl-3-methyl-quinoxaline-2-carboxylic acid was synthesized, used 4-methyl-2-nitroaniline as the start material via six steps, such as oxidation cyclization, bromize reaction, hydrolysis, Beirut reaction, reduction, hydrolysis. This work established basis for producing the high affinity antibody and developing the sensitive ELISA residue detection method.

本论文认为导致ELISA检测灵敏度较低的原因，是残留标示物和蛋白偶联后的特征结构发生改变，诱导产生的抗体不能够对游离MQCA很好的识别，因此，本论文设计了能够最大化保留MQCA结构特征的系列半抗原结构，并对其合成路线进行了筛选和优化，最终以对甲基邻硝基苯胺为起始原料，经氧化环化、溴代、水解、Beirut缩合、还原、水解六步反应制备含羟甲基结构的MQCA衍生物7-羟基甲基-3-甲基-喹噁啉-2-羧酸，为制备对游离残留标示物高亲和力的抗体，高灵敏度的ELISA残留检测方法的建立奠定基础。

The method of treating high concentration, nitrophenol wastewater with high salt content is studied, and resin adsorption and electro oxidation is adopted.

A novel BB'2-type aromatic triamine containing pyridine ring was successfully synthesized by catalytic reduction of the trinitro compound obtained by a modified Chichibabin reaction in acidic medium with hydrazine hydrate.

采用商品化的原料，在酸性介质中经改进的Chichibabin反应先合成含吡啶环的三硝基化合物，再用水合肼催化还原得到一种新型的含吡啶环BB'2型芳香三胺单体。

By following the "self-assisted molecular editing" protocol first established in our labs,a number of Aphos ligands were efficiently prepared from a single starting material and they were screened for catalytic efficacy, leading to the discovery of the best-performing Aphos appended with a 3-nitrophenyl group at the C4 position.Combination of this Aphos with Pd_2 offers a precatalyst for successful cross-coupling of unactivated aryl chlorides with aryl boronic acids at room temperature.The reactions took place under mild basic conditions to produce the products in high yields.

通过我们首次提出的&自助分子剪裁&的概念从单一起始物快速合成和筛选了一系列膦配体，并发现C4位含3-硝基苯基的的膦配体和醋酸钯联用可以在室温下顺利地催化不活泼氯代芳烃和芳基硼酸的偶联反应，反应条件温和且产物收率很高。

The osteogenic differentiation markers were determined by para position Nitrobenzene phosphoric acid and Alizarin Red S staining.The expressions of CBFA1 and VEGF mRNA in BMSCs were detected by RT-PCR.

采用改良MTT法测定含药血清对P2代BMSCs增殖的影响；用对硝基苯磷酸法和茜素红S染色定量法对BMSCs分化为成骨细胞的标志物进行测定。

Bacon, sausages and other meat products, is used in the past an important means of storage of meat, one of more modern in the city to look for a style of food, generally with a small amount of nitroso compounds, because the content is not high, in food processing can be abandoned to the broth.

咸肉、香肠等肉制品，在过去是用来贮藏肉的重要手段之一，现代在城市更多的将其看为一种风味食品，一般含少量亚硝基化合物，因含量不高，在食用加工时弃去汤汁即可。
