查询词典 nitric

The same methods were used to study toluene dinitration, and the results indicated that the thermal runaway risks of these reactions were low too; prolonging dosing duration was helpful to the conversion of all nitrotoluene; decreasing the molar ratio of nitric acid to mononitrotoluene would make an insufficient conversion; among the given temperatures, rising reaction temperature couldn\'t markedly change the yield coefficient, but lead more heat generation and higher thermal runaway risk.

采用同样的方法对二段硝化反应进行研究，结果表明：二段硝化反应的热失控危险性也较低；延长加料时间，有利于反应完全；而随着硝酸与一硝基甲苯摩尔比的减小，硝化难以进行完全；在选定温度范围内升高温度，产物得率无显著变化，反而易导致放热加剧，增加体系的热失控危险。

Absrtact: Objective :T o explore the effect of endurance training on the level of nitric oxide in nonalcohol fatty liver in ApoE - knock2 out mice and its protection or oxidative injury.

摘 要：目的研究耐力运动对非酒精性脂肪肝小鼠肝脏NO水平的影响及其对肝脏的保护或氧化损伤作用。

Endurance training increased the activity of iNOS in liver , thereby in2 creasing the level of NO , but the high level of NO didn' t result in the oxidative injury of the liver. I t indicated that the protection or oxidative injuri of nitric oxide in nonalcohol fatty liver was closely related to the physiological state of life.

耐力运动引起非酒精性脂肪肝小鼠肝脏iNOS活性升高，导致 NO水平升高，而高水平的 NO并未造成肝脏的氧化损伤，说明 NO水平的升高并不一定造成氧化损伤，其是否具有氧化损伤作用与机体的生理状态有关。

Nitric oxide is a kind of gas which features in chemistry contain nonsymmetrical electron, simple structure, active property.

一氧化氮是一种含不成对电子的气体，结构简单，性质活泼，易扩散。

Objective: To observe the age changes of the age changes of the expression of nitric oxide synthase in pterygopalatine ganglion , otic ganglion and the fibers innervating the cerebral vessels of rats.

目的：观察大鼠翼腭神经节、耳神经节及脑底动脉壁神经纤维一氧化氮合酶表达的年龄变化规律。

MPH plastic magnetic pump complies with JB/T7742-1995Standard for Small Magnetic Transmission Centrifugal Pump. Its flow-through parts adopt PPS with corrosion resistance to most acid, alkali and salt (except oxidable acid like strong sul-furic acid, nitric acid and aqua regia). Its performance is close to the chemical performance of F4, which can resist to most organic solvents under 100℃, especially to the mixture of gas and carbinol. Thus it is an ideal pump for acid and alkali industries.

MPH型塑料磁力泵符合JB/T 7742-1995《小型磁力传动离心泵》标准，过流部件采用聚苯硫醚，不受大多数酸、碱、盐的侵蚀(除氧化性酸如浓硫酸、硝酸和王水等)，其性能接近于聚四氟乙烯的化学性能，在100℃以下能耐大多数有机溶剂，特别能耐汽油和甲醇的混和液，是酸碱工业中的理想用泵。

In the cardiovascular system, the endogenous NO, CO, and H2S form three specific and relevant pathways with their corresponding enzymes including nitric oxide syntheses, the home oxygenize and cystathionine-r-lyric enzyme, whose affect can relieve the atherosclerosis.

血管系统中内源性气体信号分子NO、CO、H2S作为一种独特的血管活性物质，分别与其相应的合成酶一氧化氮合酶、血红素加氧酶和胱硫醚－r-裂解酶形成独立而又相互关联的体内重要抗氧化系统，可以减少动脉粥样硬化的严重度。

In order to solve these problems, first, activated carbon which was deashed by hydrochloride was modified through using concentrated sulfuric acid, concentrated nitric acid, hydrogen peroxide and potassium permanganate in the paper, the result showed that the modification of activated carbon is best through using concentrated sulfuric acid under 250℃ through analyzing the desulfurization efficiency and acidic oxygenous group on surface.

对上述问题，本文首先采用浓硫酸、浓硝酸、双氧水和高锰酸钾等氧化剂对盐酸脱灰后的活性炭进行化学改性，通过对改性活性炭的脱硫效果及其表面酸性含氧基团分析，得出在250℃的温度下采用浓硫酸改性活性炭效果最好。

In the study, we established the animal model of diabetic ED successfully. Modern medical methods such as routine lightscopy, pathology, transmission electroscopy, scanning electroscopy, fluorospectrophotometer and radio-immunity were employed. From the aspects of pathomorphism, cellular supermicrostucture and neurocrine, we observed the mixture's effect on status of the whole animal model and penial erection, the fast plasma glucose, protein non-enzyme gycosylation, nitric oxide synthase , testosterone. In contrast with control groups, the mixture could apparently slow down the corpus cavernosum penial, vascular, neural pathologic progression of the diabetic rats and had a better result than diabetic pill, invigorating yang and restoring normal capsule and amino guanidine.

通过实验研究，成功建立了糖尿病性阴茎勃起功能障碍动物模型，利用常规光镜病理、透射电镜、扫描电镜、荧光分光光度计、放射免疫法等现代医学研究方法，从病理形态学、细胞超微结构、神经内分泌学等方面，观察了降糖起萎合剂对模型动物整体状态和阴茎勃起情况、空腹血糖水平、蛋白非酶糖基化、一氧化氮合酶、睾酮等实验指标的影响，与对照组比较提示降糖起萎合剂能明显延缓大鼠基于DM基础上的阴茎海绵体及血管、神经病变的病理进程，其疗效优于消渴丸、壮阳复春灵胶囊及氨基胍。
