查询词典 sensitive

Based on the previous literatures, the following major innovation works were carried out in this dissertation:(1) The derivatization reaction conditions of ephedrine and pseudoephedrine with sensitive derivation reagent in aqueous system were studied and two new methods were developed for the assay of them by microemulsion electrokinetic chromatography and micellar electrokinetic chromatography with LIF detection. The sensitivity and analysis times were greatly improved compared with the previous reports;(2) A new method of CZE with indirect LIF detection was developed for the simultaneous determination of six coumarin compounds (esculin, esculetin, isofraxidin, genistein, naringin and sophoricoside) with fluorescein as the probe. The proposed method enlarges the application range of LIF detector, and provides new approach for the analysis of certain compounds difficult to derivatize;(3) Based on the above research, an MEKC with indirect LIF detection method for the simultaneous determination of adenine and guanine in DNA extracts from fungus, maize and soybean was established;(4) A new method for the investigation of the complexes formed between human serum albumin and ampicillin sodium under the simulated physiology conditions using laser light scattering technique was developed.

该论文在综述前人工作的基础上，开展了如下未见文献报道的创新性的研究工作：(1)使用灵敏的衍生试剂对麻黄碱和伪麻黄碱在水体系中的衍生反应条件进行了系统研究，建立了微乳电动色谱-激光诱导荧光检测法和胶束电动色谱—激光诱导荧光检测法测定麻黄碱和伪麻黄碱的灵敏分析新方法，与以前的报道相比，灵敏度和分析时间均有很大改善；(2)使用荧光素钠作为背景荧光试剂，建立了同时分析测定六种黄酮类化合物(秦皮甲素、秦皮乙素、异秦皮定、染料木素、柚皮苷和槐角苷)的毛细管区带电泳—间接激光诱导荧光检测新方法，扩大了激光诱导荧光检测的应用范围，对难衍生化合物的分离分析提供了一种新思路和新途径；(3)以荧光素钠作为背景荧光试剂，建立了一种用于同时测定食品提取DNA中的腺嘌呤和鸟嘌呤含量的胶束电动色谱—间接激光诱导荧光检测新方法；(4)用动态和静态激光散射法研究了模拟生理条件下人血清白蛋白与氨比西林钠盐相互作用所形成的复合物，为药物分子与蛋白质的相互作用、药代动力学等的研究提供了一种新思路。

In addition, the maximum velocity in larvae was significant higher than those in pupae and adults. In vitro inhibition studies of larvae AChE indicated that the I50 values of 20-d larvae were higher than those of 10-d larvae when treated with eserine, malaoxon and carbaryl, respectively, suggesting that AChE in 20-d larvae was less sensitive to the inhibitors.

通过对幼虫AChE离体抑制作用测定表明，毒扁豆碱、马拉氧磷和西维因对20d龄幼虫的抑制中浓度I50均高于10d龄幼虫，说明20d龄幼虫体内的AChE对3种抑制剂的抑制作用更不敏感。

His efficiency springs out of esprit de corps, out of care to make ingratiating obeisance to the authority of a superior, or at best, out of the soil of a sensitive conscience.

他们的效率来自"团体精神"，来自想表现对于上级权力的阿谀奉承的服从，或者从最好的角度说，来自易受感动的良心的土壤。
