氮化

We recommend a CFA method that can determine total nitrogen and kjeldahl in one channel with evolution Ⅱ machine.

本文就仪器化检测总氮和凯氏氮进行了一系列的探索和研究。

Soil easily mineralizable nitrogen ; microbial biomass nitrogen ; biological available index

易矿化有机态氮；微生物态氮；生物有效性

The copolymer of N isopropylacrylamide and acrylamido azobenzene was synthesized for the study of the effect of the photoisomerization of a water soluble copolymer containing azobenzene groups on the photocontrolled release behavior of liposomes.

为了研究侧链含有偶氮苯基的水溶性共聚物的光异构化对脂质体内包容物的光控释放的影响，设计合成了N－异丙基丙烯酰胺和丙烯酰胺基偶氮苯的共聚物。

The nitrogen in the coal exists in the forms of pyridine (N-6), pyrrolic and pyridone (N-5), quaternary nitrogen and nitrogen oxides. The N-Q near 401.5eV is assigned to a protonated or oxide form of pyridinic nitrogen. On this basis, the nitrogen in six-membered rings is the dominant in Yibin coal.

研究结果表明，宜宾煤中氮的官能团有4种，即吡啶(N-6)、吡啶(N-5)、质子化吡啶和氮氧化物，其中吡咯含量最大，煤中的N-X就是N-O，是煤中吡啶结构氮与氧直接结合的结果。

In Eucalyptus forestland, soil organic carbon, total nitrogen, available potassium contents and soil PH decreased significantly; soil available phosphorus and exchangeable magnesium contents, net nitrogen mineralization rate and ammonification rate also decreased but showed no significant difference. In shrubland, soil exchangeable calcium content increased significantly, but the contents of other nutrients had no significant change.

结果表明：火烧3年后，桉林土壤有机碳、全氮、速效钾和pH含量明显降低，土壤有效磷、交换性镁、土壤净氮矿化速率和氨化速率降低，但不显著；火烧灌草坡除土壤交换性钙明显增加外，其他土壤养分均无显著变化。

ResuIt:1. JDD can significantly improve the digestive system symptoms and physical strength of CRF patients. It can also reduce the urine protein.plasma lipids,BUN and Scr notably.The total effective rate of treatment group is 86.67%,better than that of control group(P.05).2.The experiment revealed JDD can restrain the crescendo-developed mechanism of CRF,which is achieved by decreasing blood ET-1,plasma lipids,urine protein etc.lt also can lighten glomerular sclerosis,inhabit uriniferous tubule-interstitial fibrosis.

结果：1。降氮汤能明显改善消化道症状及体力等一般情况，显著降低尿蛋白，血脂和血Scr、BUN，其总有效率86.67％，显著优于尿毒清对照组(P＜0.05)。2，实验发现降氮汤可通过降低血ET-1、血脂、尿蛋白等途径抑制CRF的渐进性发展机制，减轻肾小球硬化和肾小管-间质纤维化，具有肾保护作用。

We drawed a conclusion that both aboveground and belowground soil carbon input were critical to soil available nitrogen concentration, but they showed no relation with soil nitrogen net mineralization rate.

我们的结论是：土壤地上地下碳输入是影响土壤有效氮库储量的重要因素，但与土壤氮净矿化速率没有直接联系。

Nitrogen alloying process was set up by theories of nitrogen dissolved and degassed in stainless steel refined in AOD.

李永中，赵利荣，AOD炉冶炼含氮不锈钢氮合金化工艺开发

Four main saccharifying technical conditions of wheat beer influencing α-amino nitrogen content of wort including wheat malt proportiong, the ratio of water and raw materials, holding time at 52 ℃, and holding time at 65 ℃ were optimized by response surface method and the mathematical model of each factor incluencing α-amino nitrogen content was established.

采用响应曲面分析法对影响小麦啤酒麦汁α-氨基氮含量的4个主要糖化工艺参数即小麦芽比例、水料比、52 ℃保温时间和65 ℃保温时间进行优化，建立了各因素对麦汁α-氨基氮含量影响的数学模型。

Our results suggest that the mechanism leading to increased expression of 1-acid glycoprotein and consecutive increased protein binding of atracurium is not mediated by inducible nitric oxide synthase induction and nitric oxide expression.

我们的结论是1-酸糖化蛋白的表达和阿曲库铵与其结合的持续增加不是由诱导性氧化亚氮合酶和氧化亚氮所介导

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.
