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。

The thinner, weaker post-LASIK cornea is more susceptible to forward bulging due to normal intraocular pressure, which may progress to a condition known as keratectasia and corneal failure, requiring corneal transplant.

LASIK术后更薄，更弱的角膜相对正常眼压的压力来说，是更易膨胀的，发展下去，可能导致被称为角膜膨胀和角膜病变的疾病，最后需要角膜移植。

Libellula had different resistance to different races and Xiannong 4 was susceptible to all the races except CY18 and CY22. Resistant components had significant variances among different cultivars, races and cultivar×race. And Libellula had strong selection on different races, while the selection of Xiannong 4 was weaker than that of Libellula.

里勃留拉的抗性谱较宽，抗病性在小种间差异明显，而咸农4号对除CY18、CY22外的小种均感病；两者的抗病性组分在品种间、小种间以及品种×小种互作时均有显著差异；里勃留拉对不同菌系有较强的选择作用，而咸农4号的选择作用较弱。

The effect of F 1C on joint swelling and the immune respones of AA rats were evaluated by lymphocytotic reaction, flow cytometry, and ELISA. Results F 1C by ig administration to AA rats decreased the primary joint swelling of AA rats, stronger than TW and weaker than CsA, promoted the decreased splenocyte proliferation induced by Con A, and inhibited the augmented thymocyte proliferation induced by Con A in AA rats. The evaluation in vitro showed the F 1C inhibited the augmented thymocyte proliferation from AA rats and promoted the deficient IgG produced by splenocyte from AA rats.

结果 ig给予F1C(30mg／kg)对AA大鼠原发性足肿胀具有明显的治疗作用，该作用较TW强，较CsA弱；F-1C对AA大鼠低下的脾细胞增殖反应具有改善作用；对亢进的胸腺细胞增殖反应具有抑制作用。F-1C体外对AA大鼠低下的脾细胞产生IgG水平具有明显的促进作用，并能抑制亢进的胸腺细胞增殖反应。

Since they are weaker than metal, their use is limited to such conditions as nonunions of the medial malleolus and some of the small bones of the hand, wrist, or foot.

由于其强度较金属弱，它们的使用仅限于内踝和手、足、腕部短骨的不愈合。

This development of white mensural notation may be a result of the increased use of paper, as the weaker paper was less able to withstand the scratching required to fill in solid noteheads; notations of previous times, written on vellum, had been black.

这种white mensural notation的发展也许是纸张使用的增加造成的，这是由于单薄的纸张不是很能承受得了把符头填充成实心儿的刮画；其实在这之前的乐谱的符头是黑色的。

Myoblastic cells from patients with PM had a weaker ability of developing into the myotubules, thus they were unable to perform effective regeneration, which resulted in a progressive necrosis. The exogenous bFGF could promote the division and proliferation of the muscle cells in vitro . These results shield a light on bFGF's potential role in preventing and treating PM.

PM患者受损腓肠肌在体外有再生能力，但融合成肌管能力极弱，存在再生障碍，不能对变性、坏死的肌纤维形成有效再生，故呈进行性肌纤维耗竭；外源性bFGF可促进PM患者体外培养骨骼肌细胞增殖分裂，并可促进肌管成熟，对进展性肌病应具有防治作用。

Perhaps this is more noticeable because of the weaker bass presence, and the narrowish soundstage, which could shift attention to these areas of the frequency band.

也许是因为低音呈现缺少的原因，这方面更明显。

The south had a weaker war resource base, and its society had its internal contradictions and conflicts between slaveholders and slaves and nonslaveholding Whites, these disadvantages limited its war strength buildup.

南部战争资源基础薄弱，社会内部又存在着奴隶与奴隶主的对立，以及奴隶主与非奴隶主白人大众的矛盾，这些不利条件制约着南部战争力量的组建。

Simulations of echo intensity,maximum precipitation without orographic effects are much weaker than observations;and they are much improved and closer to the reality after consideration of orographic effects.

理想地形的对流过程虽然不能模拟出对流群中多单体的生消过程，但最大降水强度和累积降水都比平坦地面的大，更接近实测结果。

We have limited budget let me know if you can do this competitively.
