Both the and DtV$ for the glycyl dipeptides increase with increasing molality of sodium acetate. The interactions between charged center or glycyl units of the peptide and ions dominate those between alkyl groups of the peptide and the ions. The interaction between the peptides and sodium acetate is mainly pairwise. The results were interpreted successfully by the cosphere overlap model.

结果表明:甘氨酰二肽的标准偏摩尔体积和标准偏摩尔转移体积均随乙酸钠浓度的增加而增大,溶液中离子与肽带电基团/甘氨酰基团(CH2CONH)之间的相互作用大于离子与肽的非极性基团间的相互作用,乙酸钠和甘氨酰二肽之间主要是对相互作用。

In order to reduce the corrosion of acidic paint stripper to aeronautical metals and provide with better anti-corrosion additive for AIL4130, TC4, LY12, and 20(superscript #) steel, a series of inhibitors and their composite were investigated. Weight loss experiment, Tafel curves measurement and SEM observation were carried out for the above metals in the formic acid solution which was normally used in the paint stripper. The experimental results indicate that the optimizing composite inhibitor consists of sodium benzoate, 2-thiourea, hexamethylenetetramine, sodium laurylsulfonate and 1, 2, 3-benzotriazole.

为降低酸性脱漆剂对飞机金属材料的腐蚀,以脱漆剂中经常使用的甲酸水溶液为研究介质,以AIL4130、TC4、LY12、20钢等材料为研究对象,通过腐蚀失重法、塔菲尔曲线测量和SEM观察,筛选出对以上各金属材料缓蚀效果较好的复配缓蚀剂体系,即苯甲酸钠、硫脲、六次甲基四胺、十二烷基磺酸钠、苯并三氮唑等缓蚀剂的优化组合。

Voltage-gated Na+ channel 1.8 contributes to the majority of the Na+ current that underlies the depolarizing phase of action potentials. Nav1.8 is mainly distributed intracellularly and its current amplitude can be enhanced by the β3 subunit.

电压门控钠离子通道是可兴奋细胞产生动作电位的基础,Nav1.8是特异性高表达在背根神经节初级感觉小神经元中的一种电压门控钠离子通道,它与疼痛的产生有密切的关系。

There is a lag of 3–5 days between the beginning of spironolactone treatment and the onset of the natriuretic effect.67 Controlled studies have found that spironolactone achieves a better natriuresis and diuresis than a ''loop diuretic'' such as frusemide.68–71 Most frequent side effects of spironolactone in cirrhotics are those related to its antiandrogenic activity, such as decreased libido, impotence, and gynaecomastia in men and menstrual irregularity in women (although most women with ascites do not menstruate anyway).

在应用螺内酯治疗开始和出现尿钠排泄之间会有3-5天的延迟。67对照研究发现螺内酯较绊利尿剂如速尿能取得更好的排钠和利尿效果。68-71螺内酯在肝硬化中大部分常见的副作用与其抗雄激素活性有关,如男性性欲降低,阳萎和男性乳腺发育,而在女性则为月经紊乱(虽然大多数有腹水的女性不来月经)。

Shifts of the highest occupied molecular orbital and the secondary electron cutoff of the PES spectrum upon the adhesion of the Alq layer have been observed, revealing the existence of the interface dipole. Results of angle-resolved X-ray photoelectron spectroscopic measurements confirm that the C_(17)H_(35)COONa molecules tend to arrange themselves in an amphiphilic array at the interface.

通过紫外光电子能谱得到了界面处的电子结构与能级排布,并观测到了界面偶极层的存在;同时利用角分辨的X射线光电子能谱研究了硬脂酸钠分子在Alq表面上沉积时,分子排布的取向,结合分子结构,解释了有机发光器件中在金属电极和Alq间加入一薄层硬脂酸钠后性能得到有效改善这一现象。

The contrast experimental analyses on the spray voltage, pinhead size and other influential factors are carried out.

In order to improve their water solubility, 4"-fatty amido-3"-sodium carboxylate azobenzene-4-sodium sulfonates were synthesized. They are azo compounds with two hydrophilic groups of carboxyl and sulfonyl. They decrease the surface tension in dilute solution slowly, and show some surfactivity, but are not surfactants. The probable reason is their relative strong hydrophile. Furthermore, their colors are not fresh and far from our destination.
