烟酸

With the varying of potential the adsorption behavior of picolinic acid is invariant, while the adsorption behavior of isonicotinic acid and nicotinic acid may change. The probable reasons are given.

分析表明在电极电位负移过程中皮考酸分子一直采取通过羧基和苯环上的N原子侧立吸附在银电极表面，与之不同的是，异烟酸分子和烟酸分子在表面的吸附状态都随电位改变发生了变化，我们对此进行了分析和解释。

The potential response mechanism is based on the doping effect of nicotinic acid within PPy film.

传感器的响应是基于烟酸根离子在掺杂了烟酸的聚吡咯膜中掺杂=释放平衡。

The potential response mechanism is based on the doping effect of nicotinic acid within PPy film.

传感器的响应是基於烟酸根离子在掺杂了烟酸的聚咯膜中掺杂=释放平衡。

This acid is called "picolinic acid" When food containing zinc or zinc supplements reaches the small intestine and duodenum, the pancreas excretes picolinic acid.

这种酸是所谓的&烟酸&当食品含有锌或锌补充剂到达小肠和十二指肠，胰腺排出，烟酸。

The first laboratory isolation of vitamin B3 occurred during research studies of tobacco in the 1930s, hence niacin is also known as nicotinic acid.

第一个实验室分离维生素B3的研究过程中发生的烟草在1930年，因此，烟酸也被称为烟酸。

Further study revealed that nicotinic acid lowered the thermal transition temperature of the silver source and the values of pH and pAg in the emulsion of the said material.

进一步实验结果表明，烟酸的引入会降低材料的pH、pAg值和银盐的相变温度，硬脂酸银与烟酸一起加热可能反应生成了新的化合物。

Niacin, Niacor and Slo-Niacin are common names for nicotinic acid agents.

烟酸， Niacor和斯洛伐克，烟酸是常见的名称，烟碱酸剂。

Ounces of beer for 9% of the human body to provide the required day of vitamin B6 and nicotinic acid, nicotinic acid helps protect the nerve tissue.

12盎司啤酒的9％，人体提供维生素B6和烟酸需要一天，烟酸有助于保护神经组织。

The methods of IR and others were carried on in order toverify the structural formula of XN. The validation of analytical procedures wasconducted according to quality standard of XN in supplement of ChinesePharmacopoeia in 2002. The results show that the structural formula of XN isright and XN can be analysed in accordance with the quality specification of ChP.The results of three lots repeat tests show that the optimal process for XN wasrepeated excellently and quality of products is stable and controllable.

所合成的烟酸占替诺经红外分光光度法等波谱测定，证明其结构正确；经检验方法学验证，确证该产品适用于按《中国药典》质量标准检验；经三批次重复验证试验，结果表明优选的烟酸占替诺合成工艺重现性好，所得产品质量可控，收率为91.1%，接近文献报道的最高收率。

The sensor show Nernst response for 20× 10〓～50×10〓mol/L nicotinic acid with detective limit of 2.0×10〓mol/L, other advantages of the sensor include resistance to poison、 fast response et al..

用电化学方法制备的烟酸-PPy化学传感器对2.0×10〓～5.0×10〓mol/L浓度范围内的烟酸有良好的Nernst响应，传感器具有选择性好、响应快、制备容易等优点。
