负电荷

An anion in which carbon carries a negative charge and an unshared pair of electrons.

As these hydrometeors jostle about, updrafts push the smaller positively-charged particles towards the top of the cloud, leaving the negative charges concentrated at the bottom.

当这些水气凝结体相互聚集并发生碰撞时，上升气流会推动带正电荷的较小的颗粒向云层上方移动，剩下带负电荷的较大颗粒，则聚集在云层下方。

Zwitterion An ion with both a positive and a negative charge.

两性离子：既带有正电荷又带有负电荷的离子。

Methods 34 heroin addicts were equally divided into treatment group and control group.Based on substitution of Methadone decreasingly,the patients of treatment group were additionally treated with aerosl bioelectricity apparatus(which generates negative charge with 1×107/cm3),once a day,for 7 days.Each patient was inhaled negative charge for 120min.

对海洛因依赖者34例分为两组，在美沙酮替代递减治疗的同时，治疗组采用珠海产SQ-365型气溶胶生物电理疗仪，以发生1×107个/cm3的负电荷吸入120 min，每天1次，治疗7 d 后观察血、尿吗啡含量及临床症状。

The remaining negative charge can be spread out, or delocalize over three atoms

剩下的负电荷被分散或离域遍及到三个原子。

The clinical symptoms were markedly improved at 3 days of post-treatment,obvious difference of total mark was also appeared between the treatment group and control group.Conclusion It is suggested that inhalation of negative charge can strengthen the blood oxdation,regulate the funtions of nervous system,endosecretory and immunological system and decrease the dependence of drug against heroin.It is a better treatment for drug addicts.

通过吸入负电荷增强血液的氧化作用，对神经系统、内分泌系统及免疫系统功能有调整、改善作用，减少对戒毒药物的依赖性，是一种良好的对海洛因依赖者躯体戒断症状缓解的配合治疗方法。

The calculational results are in good agreement with the X-ray data and show that different substitute group results in different charge distribution, the exocyclic sulfur atom has the biggest negative charge value and this site is the most likely site of protonation and methylation as well as the potential coordination site with metallic ions.

计算结果与X-射线衍射数据相符合，并显示虽然不同的取代基导致了不同的电荷分布，但四唑环外的硫原子总是具有最大的负电荷分布，从而使其成为最有可能的质子化、甲基化及与金属离子进行反应的点位。

From analyzed two typical flashes, we find that the early stage of the intercloud discharge process is similar to the PBP process of normal CG discharge.

两次闪电的个例分析发现该云内放电过程的前期类似于常规地闪的预击穿过程，可能起始于云中部的负电荷。

The poly chains can clearly function as steric stabilizers by binding to the gold surface through the thioether but may also (unlike, for example, PEG-SH)4d,h play an electrostatic role due to the potential for this water-soluble ionizable polymer to carry a negative charge.

这个聚甲基丙烯酸链可以很清楚的功能空间稳定器对黄金表面，但也可以通过thioether(不像，例如，PEG-SH)4d，发挥静电作用有潜力的ionizable这类聚合物带负电荷。

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。
