带负电荷的离子的

The results of the present research are as follows, The correlation between physico-chemical properties of organic compounds and their competitive power was studied, and it was indicated that organic compounds preferable to form H-bonding with organic matter of sorbents have stronger competitive power; Sorption behaviors of ionizable organic compounds in different species and their competitive power were examined, and the results showed that phenols and carbonxylic acids with benzyl circle have much stronger competitive power in molecular species than in ionized species, because negative charges of anionic forms can depressed their adsorption on the surface of the sediment; in contrast, organic bases such as aniline and p-chloroaniline show weaker competitive power in molecular species than in ionized species, and this is because both species of the organic bases could adsorb strongly onto the sediment; there is a correlation between competitive power of organic pollutants in multi-solute systems and their sorption isotherm nonlinearity in single-solute systems, and organic compounds whose sorption isotherms is linear in single-solute systems hardly have competitive power in multi-solute systems; Competitive sorption effects in more than two-solutes systems was studied, and it was exhibited that mixture of two cosolutes each of which could suppress sorption of nominal solute onto the sediment had synergistically competitive sorption effect on the nominal solute; A method about incorporating sorption/desorption of organic pollutants into river water quality model was developed, and discussion about degree of sorption/desorption effect on model prediction for different organic compounds was made, which will provide theoretical basis and practical processes for setting up more accurate water quality model.

论文主要取得了以下研究成果。(1)有机化合物的吸附竞争能力与其物化性质具有相关性，易与沉积物有机质形成氢键的化合物其竞争能力也比较强；(2)可离子化有机化合物的吸附竞争能力与其存在形态有关。酚类、含苯环的羧酸类化合物，其离子态的吸附竞争能力远小于分子态，其机理为有机酸阴离子所带的负电荷抑制了表面吸附能力，主要发生分配作用；而苯胺类化合物，其离子态和分子态都表现出显著的竞争能力，而且离子态的竞争能力略强于分子态，原因在于有机碱阳离子所带的正电荷促进了其表面吸附能力；有机化合物竞争能力的强弱与其单组分吸附等温线的非线性程度具有一定的相关性，吸附等温线近似为线性的化合物没有或只具有微弱的竞争能力；(3)对目标有机化合物的吸附具有竞争效应的有机化合物混合后，将对目标有机化合物的吸附产生协同竞争效应；(4)以京杭运河为例，率先提出了将有机污染物的吸附／脱附作用及水文水力参数耦合到水质模型中的方法，并讨论了吸附／脱附作用对不同有机污染物预测模型的影响，为建立更准确的水质模型及进行更客观的风险和生态评估提供了参考依据。

Objectives and methods: The present study is undertaken to examine our hypothesis that with the accumulation of ion channels, increased sialic acids at the injury site or DRG somata result in a reduction of net transmembrane potential that evoke ESD in injured neurons.

膜蛋白的一个共同特性是其膜外域接受密集的糖基化，糖基含有大量带负电的唾液酸，如大部分离子通道，特别是电压依赖性的钠通道含有大量的唾液酸，而且这些负电荷靠近钠通道的电压感受器而易化通道开放。

Depression mechanism of sodium silicate on Titanaugite was that silicon acid colloidal particles with negative charge were formed by oxidate polymerization, adsorpted on the mineral's surface, provided the minerals with hydrophilicity, and consequently, Titanaugite was depressed.

水玻璃对钛辉石的抑制作用主要表现在：在弱酸性介质中，通过氧联反应聚合成的、带负电荷的硅酸胶粒在矿物表面吸附后，使矿物表面亲水，阻止了有机捕收剂羟肟酸在钛辉石表面与金属离子键合。

One valley lied between two peaks(flower beginning period and fruit maturating period).When meeting blood serum,the electron on the ring B-C and A-C of quercetin molecule would move and make -OHs of Ring B and A ionizated and one anion with double negative charge would present.

遇到血清时，槲皮素分子结构中的B环和C环、A环和C环形成的两套共轭体系中的电子，发生转移并使酚羟基解离，形成带双负电荷的阴离子，此阴离子将与人血白蛋白结构中结合位点上的氨基酸残基以离子键的形式结合。

When purify carries the suspension colloid grain of negative electric charge in natural raw water, it is OK that its element linear grows the positive electrical charge that contains in catenary to be opposite remove electric sex to counteract the double function that reachs adsorption to bridge at the same time, and water-solubility of starch of this kind of modified is good, burnt viscosity is stable, cast impose kind agile, it is a kind of function exceedingly good organic, inorganic and compound high polymer garrulous coagulates agent.

在去除天然原水中带负电荷的悬浮胶体颗粒时，其分子线性长链中所带有的正电荷对可以同时起到电性中和及吸附(物质表面吸住周围介质中的分子或离子现象)架桥的双重功能，而且这种改性淀粉水溶性好，糊粘度稳定，投加方式灵活，是一种性能优异的有机-无机复合高分子絮凝(使液体中悬浮微粒集聚变大或形成絮团，从而加快粒子聚沉，达到固-液分离的过程)剂。

The production of the reaction was boehmite.
