It is of negativ twact on the fonnin of foriihaho if too muc or too liul normal hexanl . the wi of cosurftw has no effed on the uvth absorptio of lermulsion . in the system of 8 : 2 normal heptane : normal hexanl , wphg can form lermulsion unde fferent saponification 在8 : 2的正庚烷正己醇体系中,不同皂化摩的hhophg均能形成微乳液,随皂化度的增加微乳液的液滴直径逐渐增大,透射电镜测试得到类似的结果。
As to the solvent , hexane and butvul acetate is discussed and former is more suitable for biotransformation . among seven kinds of energy source : menthok alcohok glycok glycerou 1 - hexanok butyl alcohol octyl alcohol , glycol is selected as energy source , so hexane - glycol is used as reaction system 从生物相容性和有利于转化的角度对两种溶剂,正己烷和乙酸丁酯进行了比较,确定了正己烷?忆二醇为该模型反应的溶剂体系。
The analytical method for five pesticide residues of pyrethroid , such as fenpropathrin , cypermethrin , fenvalerate , deltamethrin and bifenthrin in potable water and source water determination by capillary gas chromatography at the same time , with n - hexane for extracting agent 摘要以正己烷为萃取剂,采用毛细管气相色谱法同时测定生活饮用水及水源水中甲氰菊酯、氯氰菊酯、氰戊菊酯、溴氰菊酯和联苯菊酯五种拟除虫酯类农药残留量。
Extracting oat oil with aceton , petrobenzine , ethano - aceton and n - hexne from oat , determining quality of physical and chemic about acidity value , iodic value , saponification value , unsaponification , colour and melting point , analysis on composition of fatty acid on oat oil 摘要分别以乙醚、丙酮、丙酮乙醇、正己烷对燕麦进行萃取,对所得油脂进行酸价、碘价、皂化值、不皂化物、色泽、熔点等理化性质的测定,同时对燕麦油的脂肪酸组成进行分析。
The diameter of pn of lermulsion increases with the increasing of sapomn and it is observed through tem that the water phase drop also becomes bndr . ( 2ap uvmi absorption of formulsion changes when the quanty of cosum and the quantity of normal hexanl changes , wtheh indicatcs tha the changes influence the electron clound of benzene and thexyl ( 2 )紫外光谱的分析表明,随hhophg皂化度和助表面活性剂正己醇用量的改变,微乳液中hhophg紫外吸收峰的位置和强度发生变化,表明在微乳液的形成过程中, hhophg的苯环和竣基上的电子云密度发生了变化。
No probe leakage was found when the sensor dipped in ethanol and n - hexane for 15 days . this technique is limited for its prolix procession and request of special active function in the structure of molecular probe , sol - gel : the development of sol - gel technique provides a convenient way to incorporate molecular probe in porous inorganic material 化学键合法:分子探针通过化学反应键合于固定相,在溶剂中不泄漏,提高了传感器使用寿命,在乙醇和正己烷中浸泡15天,未见探针分子泄漏。但繁杂的过程和对探针分子结构的特殊要求限制这一方光纤化学传感器、仪器系统的研制们比生物和环境监测中的应用(摘要) 2法的应用。
The study conducted research on the following four fields : firstly , the characteristics of the interfacial polymerization system of piperazine aqueous solution / trimesoyl hexane solution were systematically investigated . the results show that at a certain molar ratio between the two monomers , piperazine and trimesoyl , at the two phase interface , a dense functional layer of ultra low pressure , high permeating flux and high salt rejection formed by controlling the time of interfacial polymerization , such as the composite membrane ( i ) , the concentration in water phase is 0 . 4 % , and 0 . 1 % in organic phase , and the polymerization time is 1 minute 本文主要进行了四个方面的研究,首先系统分析和研究了哌嗪水溶液均苯三甲酰氯正己烷溶液界面聚合体系特征、界面聚合反应中各影响因素对膜性能的影响等,结果发现,当界面处两相单体(哌嗪和酰氯)分子摩尔比为某一比值时,通过控制界面聚合时间(有机相处理时间) ,可以形成超低压高通量高脱盐的致密功能层,如复合膜( ) ,水相浓度为0 . 4 ,有机相浓度为0 . 1 ,聚合时间1min 。
All the 4 extractions showed obvious pharmacological effects by decreasing the area of myocardial infraction of the model rats , increasing the amount of blood stream of the isolated guinea - pig hearts and reducing the beating rate and amplitude of cultured myocardial sheets of mice 方法:采用冠状动脉结扎致大鼠急性心肌缺血模型,观察革叶猕猴桃果实70 %乙醇提取物、正己烷部位、氯仿部位及正丁醇部位对急性心肌梗塞范围的影响,同时观察上述部位对豚鼠离体心脏冠脉流量及小鼠胚胎心肌培养细胞功能的影响。
" original significance about the scripture of ethics " put forward definite demands about morality for rulers and discussed such aspects , comprehensively , as the importance of accomplishment about emperors ' morality , the love of the masses , ruling justly , modesty and honesty , restraining violence by peaceful means , calmness in speech and manner , being expert in choosing a person , encouraging frugality , setting a good example for the others while being strict to one ' s own 摘要《道德经原旨》对治人者的道德修养提出了明确的要求,从帝德修养的重要性、爱民之心、执政为公、不骄不争、谦虚逊让、以柔制刚、诚信待人、言行稳重、知人善任、崇俭知足、正己正人等方面作了全面论述。
