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。

Based on the physical meaning of each term in the linear parameter log I (a constant correlating the affinity of solut e t o stationary phase) of stoichiometric displacement model for retention o f solute, the thermodynamic characteristics of log I of solute in revers ed-phase liquid chromatography were investigated theoretically. This poi nt was tested by experimental data with two linear relationships:(1) plot of log I vs 1/T with apolar, polar small solut es and proteins;(2) plot of log I vs log Po/w (partition co effi cient of solute between n-octanol and water) with apolar and polar smal l solutes.
依据液相色谱中溶质计量置换保留模型及线性参数log I(与1 mol溶质对固定相的亲和势大小有关的常数),通过作图得知非极性和极性小分子溶质及生物大分子的log I与绝对温度的倒数1/T,以及小分子溶质的log I与其在正辛醇-水中分配系数的对数log Po/w呈线性关系,从两方面进一步证明了log I具有热力学平衡常数的性质。

An alternative term used for kosmotrope is 'compensatory solute' as they have been found to compensate for the deleterious effects of high salt contents (which destroy the natural hydrogen bonded network of water) in osmotically stressed cells, but again behavior as a kosmotrope in one system does not mean that a solute may behave as a 'compensatory solute' in another or even that it will stabilize the structuring of water in a third.
另类术语,用以kosmotrope是'补偿性溶质',因为他们已经发现,以弥补因有害影响。高盐含量(破坏自然的氢键网络的水),在osmotically强调细胞但同样的行为作为kosmotrope在一个系统并不意味着溶质可能像一个'补偿性溶质的另一个甚至认为它会稳定的结构水的三分之一。

Caused by disc brake on the brake Wheel Cylinder could not return to places 4 possible: First, 5 foot brake valve exhaust port blocking, high-pressure gas instinct platoon atmosphere, caused by gas-liquid master cylinder of the spring could not return to place, resulting in the system move oil, brake disc brake Wheel Cylinder Piston top dead and could not return to places; second is to the disc brake master cylinder gas-liquid pipeline blockage, resulting in brake Cylinder piston can not return to place; third master cylinder of the gas-liquid Spring itself can not return to position, brake fluid under high pressure gas can not return Axial pump to gas-liquid master cylinder reservoir chamber, resulting in brake Cylinder piston can not return to places; Fourth Wheel Cylinder piston disc brake system, due to moving fluid dirty or rusty card dead and can not return to the piston position.
造成盘式制动器上的制动分泵不能回位有4种可能:一是脚制动阀5的排气口堵塞,高压气体本能排人大气,造成气液总泵的弹簧不能回位,导致制动油将盘式制动器的制动分泵活塞顶死而不能回位;二是气液总泵至盘式制动器的油管堵塞,造成制动分泵活塞不能回位;三是气液总泵的弹簧本身不能回位,制动液在高压气体作用下,不能回到气液总泵的储油室,从而造成制动分泵活塞不能回位;四是盘式制动器制动分泵活塞由于制动液太脏或活塞生锈卡死而不能回位。

The results show that under crop rotation of wheat and maize in damp soil and brown soil, stalks return to fields integrated with applying potash fertilizer can keep K balance within a cycle and K return rate reaches 109.1%~111.9%, annual wheat stalks return to fields can provide 226.5~261.0 kg/hm2 K, meanwhile the K return rate reaches 95.2%~97.1% for only applying potash fertilizer; under crop rotation of wheat and soy bean in grittiness black earth, only applying potash fertilizer can also keep K balance within a cycle, its K return rate reaches 119.9%, meanwhile the K return rate reaches 142.0% for stalks return to fields integrated with applying potash fertilizer, which result from maize being much more absorption to K than soy bean.
在砂姜黑土区小麦+大豆轮作制度下,即使小麦秸秆不还田,仅施用化学钾肥,亦能维持小麦-大豆轮作周期钾素的平衡。施钾配合秸秆还田处理,钾归还率达142.0%,施钾且秸秆不还田处理钾归还率达119.9%。主要是大豆不象玉米那样带走较多的钾造成的。

It was indicated by the CALPHAD that the solute content at the end point of primary solidification changes synchronistically with the start point, solute content in dendritic arm and the partition coefficient increase with the solid fraction. Simple Scheil equation was shown to be able to calculate the eutectic amount on the base of partition coefficient calculated by thermodynamics, its prediction for the different solutes is self--consistent and agreeable with the CALPHAD. The eutectic amount and SDAS was measured in DC experiment and compared to model value, it was shown that the experimental data are in agreement with the model prediction.
