与此同时，首次应用微量热法对针铁矿表面吸附〓磷酸根离子反应中的热量变化进行了探讨，以揭示重金属阳离子和阴离子在土壤胶体与粘粒矿物表面吸附反应的机制。

In different softeners, anionic and cationic yellowing of the most serious, and to the yellowing of polyvingl loition.

在差别的柔软剂洋，以阴离子和阳离子型的泛黄最惨重，而以聚乙烯乳液的泛黄较少。

In Chapter 6, Five kinds of different pesticides, such as simazine, atrazine, carbaryl, ametryne and prometryn were separated by CE technique and the effects of experiment parameters including pH, the concentration of surfactant and organic modifier on the separation were investigated.

采用毛细管电泳法对5种农药(西玛津、阿特拉津、扑草净、莠灭津和西维因)进行了分离研究，考察了溶液的pH值、胶束浓度和有机改性剂对分离的影响，添加阴离子表面活性剂的胶束毛细管电泳法可使各组分达到基线分离。

The effect of addition of calix [4] pyrrole on the retention of anions and amino acids is consistent with the hydrogen interaction abilities of calix [4] pyrroles with analytes.

首次将杯[4]吡咯用作CE的电解质添加剂，对卤素阴离子及氨基酸的分离作了初步探讨，杯[4]吡咯对分析物保留的影响程度与它和各分析物形成氢键能力的大小顺序一致。

It was first reported that calix [4] pyrroles, as additives in CZE, could affect the separation of halide ions and amino acids.

首次将杯[4]吡咯用作HPLC涂敷固定相，用纯水作流动相，对三种有机阴离子及六种酚类化合物进行了有效的分离。

In this paper, different methods of preparation about magnetorheological fluids are introduced, including mechanical crushing, wet chemical depositing, anion exchange, pyrolyzing; some main applications of magnet...

介绍了制备磁性流体的几种不同的方法：机械粉碎法、湿式化学共沉法、阴离子交换树脂法和热分解法；介绍了磁流变技术在密封、阻尼器、抛光装置等工程上的一些主要应用，并展望了磁流变技术在建筑、航天等领域的应用前景。

In this paper, cationic rosin sizes were prepared by premixing anionic dispersed rosin size with extremely pure ployaluminum chloride with different basicities.

以不同盐基度的高纯聚合氯化铝为原料，按不同配比分别与阴离子分散松香胶，在一定条件下进行预混合反应，制得PAC改性阳离子分散松香胶。

The coordinated COD of 3 and 4 can be replaced by carbon monoxide to yield the corresponding dicarbonyl species [(C,N-pyN^C-R) M2]BF4 (14, M= Rh; 15, M= Ir). Ligand substitution of 11a by phosphines and azide causes the de-complexation of pyridinyl-nitrogen donor to generate the corresponding carbene rhodium complexes [(C-pyN^C-Mes)RhPR3] (17a, R = Ph, 17b, R = Et) and [RhN3] (19), respectively, indicating the labile nature of steric-hindered pyridinyl-nitrogen donor.

螯合错合物的吡啶配位，可以容易被σ-予体，如卤离子、叠氮阴离子、膦试剂，置换；但是铑与铱金属螫合物与π-酸试剂，如一氧化碳、异腈，则发生COD被置的产物14a与16；与三甲基亚磷酸酯反应时，COD及吡啶均会被取代而得到单芽的三铑-碳烯错合物18；双膦化合物则会取代铑金属上全部的配位基。

It is instantly oxidated into nitrite and nitrate that are stable end products in vivo, and also destroyed by superoxide anion.

NO在体内很快被氧化成硝酸盐〓和亚硝酸盐〓，同时亦被超氧阴离子破坏〓，〓和〓是体内NO最终的稳定产物。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
