The experiment analyses the esterase volume of Catecholamines and Acetylcholine in blood,nervous tissue and spleen tissue by way of Chromatography With Electrochemical Detection,detects the volume of aminophenol nervoustransmmiter in nervous tissue by way of automatic amino acid analyzer,and reflects the immunity function of spleen by using the spleen index,the cabability of T lymphopoiesis of spleen,the sub-T lymphocyte of blood.

应用高压液相色谱—电化学检测法和生化比色法分别分析血液、神经组织和脾脏组织中的儿茶酚胺和乙酰胆碱酯酶含量，应用氨基酸自动分析仪检测神经组织中的氨基酸类神经递质含量，以脾脏系数、脾脏T淋巴细胞增殖能力、血液T淋巴细胞亚型等指标反映脾脏的免疫机能。

It involved the converstion of vanillin into hydrazine (4) and the metalic reduction of hydrazine 4 into the intermediate vanillic amine.

以价廉易得的香草醛为起始原料，经过3步反应，高产率合成了酚羟基由对甲苯磺酰基保护的香草胺类化合物5。

However, for pentachlorophenol degradation, it is necessary to add over-dosage of oxidation reagent to mineralize PCP completely.

芬顿反应具有强氧化力，能对难分解有机物进行氧化作用，但若要对五氯酚(pentachlorophenol， PCP)这类含氯量甚高之芳香族化合物达成完全矿化分解，则需要添加大量的试剂，所费不赀，且对於污染场址现地施行时，其过程对环境冲击太大。

A series of multi-pedal amino-compound with naphthol groups have been synthesized in this work. The photo-physical behaviors of these compounds in different solvents and different pH conditions have also been studied in details.

本工作合成了一系列带萘酚基的多足胺类化合物，对它们在不同溶剂及不同pH条件下的光物理行为进行了详细研究。

Objective To investigate the application of diclofenac sodiumin perfusate during vitrectomy and its effects on retinal structure of rabbit eyes,and search the safe dose of DFS used in eyes.

目的研究非甾体类抗炎药双氯酚酸钠(diclofenacsodium，DFS)在兔眼玻璃体切割术灌注液中的应用及其对视网膜结构的影响，寻找此药眼内应用的安全剂量。

The paper reviews the characteristics of phenol compounds and the progress on modification of these compounds in recently years.

综述了天然酚酸类化合物的性质及近年来对其改性的新进展。

It also recommends some suggestions on modification of these phenol compounds in the future.

提出了今后采用生物方法对天然酚酸类化合物进行改性的一些建议。

But changing range of PAL activity or content of total phenolate and flavoniods between healthy spikes and infected spikes were related negatively to scab-resistance.

材料抗赤性强弱与接种穗与健康穗之间的PAL活性及总酚、类黄酮含量的增加幅度呈负相关。

The dynamic changes of physiological and biochemical indexes of healthy spikes and inoculation ones of the resistant mutants indicated that PAL activity and content and changing tendency of total phenolate and flavoniods and MDA in the healthy spikes of the mutants were similar to that of their susceptible donors, whereas, for the inoculated spikes, content and changing range of these indexes existed significant difference between two kinds of strains, changing from high-resistant variety (Sumai3 ) to their susceptible donors.

以典型抗扩展品种和突变体供体亲本为抗、感对照，对抗赤霉突变体的健康穗及接种穗的生理生化特性研究结果显示，在健康穗中，抗性突变体的PAL活性、总酚、类黄酮及MDA含量及变化趋势与其感病亲本相一致，但在病原菌侵染后，这些生理生化物质的含量与变化程度与其亲本有了明显的差异，其变化范围介于典型高抗品种和感病亲本之间，变化趋势与亲本或抗性品种一致。
