In recognition of its important value in ion-selective electrode study, this thesis aims to develop new types of carriers. Metallorganic compounds, Metal-Schiff base complexes, heterocyclic nitrogen compounds, derivatives of calixarene,Sudan Ⅰ and dialkyldithio phosphate have been tested as carriers for all kinds of ions.

鉴于新型载体的开发在离子电极研究中所具有的重要价值，本文主要开展了这方面的一些研究工作，重点考察了金属有机化合物、金属希夫碱配合物、含氮杂环化合物、杯芳烃、苏丹Ⅰ以及双硫代磷酸脂衍生物等各类物质用作离子载体的可能性。

The results showed that Ni\+\{2+\} bonds with O\+\{2-\} of the SiO\-2 support in bidentate fashion and is terminated with the two methoxyl groups.

结果表明，负载型单核金属甲氧基配合物 Ni(OCH3) 2 / Si O2 中，Ni2 +与载体 Si O2 表面的 O2 -以双齿形式配位；在催化剂表面存在 CO2 的桥式吸附态和甲氧碳酸酯基物种两种吸附态，CH3OH则只有一种分子吸附态。

The domain structure was observed by naked eyes and microphotography after the crystal was etched with acid.

本文对采用双坩埚提拉法生长的近化学计量比LiNbO3 晶体沿其各向切块腐蚀后通过直接观察和在金相显微镜下观察，对其各个面的畴结构进行了分析。

Moreover, the relative percentage of each type of oxane bonds in the sample of APS-modified LDHs can be determined from their relative peak intensities; these results are summarized in Table 2.The oxane bonds attached on surface of AL-M can be mainly attributed to bidentate (T2)and tridentate(T3)types.

此外，相对比例的每种类型的oxane债券样品中黄芪多糖改性水滑石可确定其相对峰强度；这些结果的摘要列于表2 oxane债券所附表面的Al - M可以是主要原因以双齿和三齿（的T3 ）类型。

Three analytical solutions are given including the wet front analysis solution of double medium soil column,the analytical expression of piezometric tube water head and saturation for steady state and the analysis solution of seepage in unconfined aquifer with a periodic boundary condition.

推导了双介质土柱表层水入渗的下渗锋面解析表达式、稳定状态时测压管水头分布与饱和度分布的解析表达式，并给出了有周期性边界条件的有限潜水层内渗流自由面的解析表达式。

The trancings of condylar movement of Angle class two division one subdivision malocclusion with mandibular retrusion during mandibular movement are smooth and continual curve. There are no differences with condylar movement distances, condylar inclination and the hinge axis rotation between right and left condyle. There are no variance to movement form of the hinge axis comparing with normal occlusion. But the overlapping gender of condylar movement trace decrease than normal occlusion.

在不同的下颌运动中，双侧髁突在矢状面和水平面的运动轨迹均为光滑连续的弧形曲线，髁突位移、矢状面髁突倾斜度、水平面髁突倾斜度及铰链轴旋转度左右两侧无明显差异，铰链轴运动形态与正常牙合无明显差异，但轨迹的重复性低于正常牙合。2。

Finally, the article discussed the possible mechanism of multi-phase electrochemical degradation of wastewater through the XPS spectrum of the used catalysts surface: In the acid solutions, the electro-generated O_2 may get electrons on the porous graphite cathode and then form H_2O_2, H_2O_2 may diffused to the surface of catalyst and reacted with its active part to produce OH, which in turn can destruct organics. The catalyst functioned as both the catalyst to decompose H_2O_2 and the flocculants to sedimentate the degraded waste.

最后全文结合研究反应后催化剂表面的XPS光电子能谱推断了该体系降解污废水可能的反应机理：在酸性条件下，石墨双阳极产生的O_2被多孔扩散性石墨阴极还原成H_2O_2，并通过扩散传质作用在催化剂的表面活性中心分解为强氧化性中间产物·OH，强氧化性攻击有机物，使其降解为小分子有机物或CO_2和H_2O，催化剂在体系中即起催化作用也起吸附、絮凝作用。

Moser [14] obtained the persistence of hyperbolic invariant tori when 0 6 Rn is a fixed Diophantine toral frequency and the eigenvalues of JM (J being the standard symplectic matrix in R2m) are real and distinct.

为中的标准辛矩阵的特征根为不同的实根时，得到了双曲不变环面的保持性。

If the original T-Mac and T-MAC 2 didn't exist I'd definitely be more jazzed about the 3, but, as is, I think the changes to the shoe are too incremental.

如果没有前面的T-Mac和T-MAC 2，我肯定会对3感觉更好，但正因为有了前代，我觉得这双鞋上的改变太小了。

The robot can undertake the dangerous work of sweeping and inspecting water-cooling tubes. When the minimum thickness of the tube lower than the prefabricating value is inspected, an alarm is given and a sign is spraged on the tube. It has many advantages,such as high efficiency and safety, low cost, less work intension etc., so it is worth generalizing.
