In this study, we investigated whether preoperative gargling with sodium 1,4-dimethyl-7-isopropylazulene-3-sulfonate monohydrate (sodium azulene sulfonate, Azunol) reduces POST after endotracheal intubation. Forty patients scheduled for elective surgery under general anesthesia were randomized into Azunol and control groups.

在此试验中，我们研究了磺酸甘葡环烃钠对减少气管插管术后咽喉溃疡的作用。40个行全麻的择期术后病人被随机分配到甘葡环烃组和对照组。

The adsorption isotherms of Sodium Dodecyl Sulfonate onto wool fiber surface which experienced clean processing from an acid aqueous solution(pH3.0～3.5) by conductance method at 366K(93℃) were studied, so did the isotherms of wool adsorbing SDS from different aqueous solutions which containing various auxiliaries(containing glycol/benzalcohol and zinc sulfate).

戴丽 ，耿信鹏，林国栋采用电导法研究了366K(93℃)时经洁净处理的羊毛纤维在酸性(pH=3.0～3.5)水溶液中对十二烷基磺酸钠的吸附等温线，以及羊毛在不同助剂(含乙二醇/苯甲醇和硫酸锌)的水溶液中对SDS的吸附等温线。

Trifluoromethanesulfonic acid was found to be able to efficiently activate the benzylic sp3 C—F bond.

三氟甲磺酸被发现能够高效地活化(SP3)碳－氟键。

The influences of plating process parameters, such as sulphamate concentration, electrolyte pH value and temperature, and pulse parameters, such as cathodal current density, pulse current frequency and duty cycle, on the micro-hardness of the nickel deposit has been studied by orthogonal experiments.

利用正交试验法分析研究了主盐氨基磺酸镍浓度、电镀过程工艺参数及脉冲参数（阴极电流密度、脉冲频率和占空比）对镀层显微硬度的影响；并对相关参数进行了优化。

It is concluded that the main influence factors on the micro-hardness of the nickel deposit are sulphamate concentration and electrolyte temperature. The most hard nickel deposit layer was obtained with sulphamate concentration 700g/L, cathodal current density 5A/dm2, pulse current frequency 800Hz, pulse current duty cycle 0.6, electrolyte pH value 4.0, electrolyte temperature 70℃.

试验结果表明：主盐浓度和镀液温度是影响镀层硬度的显著因素；当主盐氨基磺酸镍的浓度为700g/L，阴极电流密度为5A/dm2，脉冲频率为800Hz，占空比为0.6，镀液pH值取4.0，镀液温度为70℃时，可以制得显微硬度最高的镍镀层。
