IEBA在DMF溶剂中与胺类化合物形成的酰胺类衍生物不仅可发出强烈的荧光，还具有较高的质谱离子化能力。

Distribution of an ionizable drug across a membrane at equilibrium is determined by the drug's pKa （the pH at which concentrations of un-ionized and ionized forms of the drug are equal） and the pH gradient, when present.

一种能解离的药物透过生物膜到达分布平衡取决于药物的pKa（药物的非解离型和解离型浓度相等时的pH）和当时的pH梯度。

A separation model of ionizable and neutral enantiomer s with cyclodextrin-sodium dodecyl sulphate micellar electrokinetic chromatography was established.

建立了环糊精-十二烷基硫酸钠胶束电动色谱中可电高及电中性-光学异构体的分离模型。

Histidine has three ionizable functional groups.

组氨酸有三个官能团。

Distribution of an ionizable drug acro a membrane at equilibrium is determined by the drug's pKa （the pH at which concentratio of un-ionized and ionized forms of the drug are equal） and the pH gradient, when present.

一种能解离的药物透过生物膜到达分布平衡取决于药物的pKa（药物的非解离型和解离型浓度相等时的pH）和当时的pH梯度。

Although most workers have found that samples containing ionizable components usually are best separated with mobile phases that have a pH less than or equal to 3 , some separations may be impossible at a low pH because components of the sample are unstable at a low pH; protonated basic compounds are eluted too soon; and required band spacings are unobtainable.

尽管许多工作者发现含有离子化组分的样品在流动相pH值低于或等于3的时候有最佳的分离，但许多样品不可能在低pH下分离，因为样品中组分在低PH下不稳定、质子化的生物碱洗脱太快、和不能达到要求的峰间距。

Compared to solvates and salts which are limited to small numbers of nontoxic solvents and ionizable drugs, cocrystals represent a very promising designable solid form of active pharmaceutical ingredients, due to their extensive species and wide application scope.

常见的固体形态如溶剂化物、盐，因为种类少或适用的药物少而在应用上受到一定的限制。所以种类多、适用范围广的共晶作为可设计的药物固体形态近年来逐渐受到关注。

The impact of temperature,pH and ionic strength on the volume phase transition of the hydrogels is studied.The result shows that the volume phase transition temperature of ionizable and thermosenstive copolymer hydrogels depend upon the hydrophilic/hydrophobic character of the comonomers...

结果表明，疏水基末端端基的疏水程度决定凝胶体积相变的速率，随着疏水性单体甲基丙烯酸酯烷基链的增长，凝胶的疏水性增强，凝胶的相转变pH向低pH处迁移；温度高于LCST时，分子间的氢键作用减弱，疏水基团间的相互作用加强，凝胶发生体积相变。

In contrast to S- and O-heterocyclic compounds, increasing ionic strength reduced the sorption of ionizable N-heterocyclic compounds (pyridine, 2-methylpyridine, quinoline, 2-methylquinoline, and isoquinoline), due to increased electrostatic competition by cations.

对比硫和氧类杂环物质，提高离子强度会减少杂环化合物的吸收（吡啶、2甲基吡啶、喹啉、2甲基喹啉和异喹啉）这主要是由于阳离子的静电竞争。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
