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 granitic enclaves in the central-facies porphyroblastic lava are subvolcanic rocks with forming age of 134.2±1.9Ma. There is another intrusion of subvolcanic rhyodacitic porphyry with age of 136.0±2.6Ma, in the contact zone of the two volcanic cycles in the western part of the Xiangshan complex. The U-Pb ages of the sub-quartz-monzonite porphyry and lamprophyre are 129.5±2.0Ma and 125.1±3.1Ma, respectively. This suggests that the extension in the Xiangshan region, began in K〓, was week, and earlier than that in the coastal region of Zhejiang and Fujian provinces. Extension in K〓 in Xiangshan and neighboring regions was much stronger, forming NE striking large red-downfaulted-basins.
相山中心相碎斑熔岩中的花岗质包体属次火山岩,其成岩年龄为134.2±1.9Ma,在相山西部两火山旋回的界面之间,存在另一类次火山岩的侵位,其成岩年龄为136.0±2.6Ma,岩性为次流纹英安斑岩;次石英二长斑岩及煌斑岩的成岩年龄分别为129.5±2.0Ma及125.1±3.1Ma,说明相山地区的伸展、裂解作用明显早于浙、闽沿海,在K〓就开始了,但规模并不是很大;而K〓时期的拉张作用在相山及其邻区表现的更为强烈,形成了大面积的呈北东向展布的红色断陷盆地。

The clinical characters of oligodontia concluded from this study are following:(1) There is significant difference that more teeth absent and more existent teeth anomalies in patients of oligodontia/S group than in patients of oligodontia/I group, and the peg-shaped upper lateral incisor is the most frequently affected teeth with shape anomaly.(2) Both of the two groups have no significant differences in number of teeth missing between maxilla and mandible as well as that between left and right side.(3) The distribution of teeth missing is bilateral symmetry in both groups, but the frequency of teeth lost are different: excluding the third molar, in oligodontia/I group, the lower second premolar is the most frequently congenitally missing tooth followed by the upper lateral incisor, while in oligodontia/S group, the most frequently missing teeth are mandibular canine and maxillary lateral incisor. Nevertheless, the first molars are the most stable teeth in both groups.(4) In oligodonita/I group, the mean mesiodistal dimensions of all type of existent teeth are significantly smaller than normal value. It is implied that oligodontia is not an isolated phenomenon, but is related to a complex of other dental changes.
对于口腔多个恒牙先天缺失的临床特点有以下初步结论:(1)综合征型先天缺牙患者较单纯型先天缺牙患者恒牙缺失数目更多,平均分别为23.9个和14.9个,且现存牙齿有更多的形态异常,分别为7/10例(70%)和6/22例(27.3%),其中最常见的是上颌侧切牙畸形;(2)两种类型的多个恒牙先天缺失患者的缺牙数目在上下颌及左右侧之间均无差别;(3)两种类型的多个恒牙先天缺失患者在缺失牙位上均呈对称分布,但在具体牙位上有所差异:不计第三磨牙,单纯型先天缺牙最常缺失的牙位是下颌第二双尖牙、其次为上颌侧切牙;而综合征型先天缺牙最常缺失的牙位是下颌尖牙和上颌侧切牙;无论何种情况,第一磨牙均为牙列中最稳定的牙齿;(4)在单纯型先天缺牙患者中,现存恒牙的牙冠宽度较国人正常值偏小,差异显著,提示牙齿形态与多个牙先天缺失有一定相关性。

As for the mesh screen type, its volume multiplied by 100% its porosity was the desirable filling amount. Having considered the forgoing findings, the researchers add up the amounts of the above two types as the filling amount of the composite micro structure, with the filling fluid being acetone. In fabricating the heat spreader, a copper pipe is added to serve the filling purpose. What is more, because the manufacturing process is not carried out in a totally clean environment, there is some noncondensible gas left, which will have a negative effect on the performance of the heat spreader. Consequently, the copper pipe has to be reserved so that the exhaust gases can be evacuated after the filling is done.
Kempers 文中可知,沟槽结构之填充量以微结构体积之80%为最佳,网格结构则是以网格体积乘上孔隙率(porosity,φ)之100%为最佳,故本研究便以两者之加总做为复合式微结构之填充量,填充液为丙酮;在均温基板之制造程序中,会加装一铜管做充填之用,且而由于制造过程并非于一完全干净之环境下完成,故板内会有一些不利于均温基板作用之非凝结性气体noncondensible gas (NCG残留,因此铜管需保留一定的长度,以方便充填完成后将废气排出之用。

Results indicate that the number of bacteria grown in media LB, CSEA and WSA was 14.84×10^7, 10.27×10^7 and 6.91×10^7 CFU per gram dry soil, respectively, after 192 h of incubation. The diversity index of soil bacteria was the highest in WSA, while the lowest in LB. Certain similarity was discovered in bacteria community between the three media, i. e. the Jaccard index was 57.69% between LB and CSEA, 53.13% between LB and WSA and 66.67% between CSEA and WSA. Phylogenetic analysis suggests that the dominant bacterial groups in the soil belong to β-Proteobacteria,γ-Proteobacteria and Actinobacteria. The sequence of 16S rDNA of some OTUs was found to have high homology with Burkholderiaceae bacterium, Rhodococcus and Mycobacterium, so it is presumed that the cells of these bacteria can secrete Resuscitation-Promoting Factors, which may effectively improve culturability of soil microorganisms.
结果表明,LB、CSEA、WSA培养基192h后每g干土获得的细菌数量分别为14.84×10^7、10.27×10^7和6.91×10^7CFU,但微生物多样性指数以WSA为最高,LB多样性指数最低;三种培养基培养的细菌菌群有一定的相似性,LB和CSEA培养基间的Jaccard指数为57.69%,LB和WSA培养基之间为53.13%,而CSEA和WSA培养基的相似性指数达66.67%;16SrDNA测序结果表明,所获得的土壤细菌优势种群在分类方面主要属于γ-和β-变形杆菌以及放线菌亚门,其中某些OTUs中的16SrDNA序列与Burkholderiaceae bacterium、Rhodococcus和Mycobacterium属具有较高的同源性,推测其细胞能够分泌复苏促进因子,有效地提高土壤细菌的可培养性。
