同时短程作用的量子力学水平处理又会产生新的误差，需采用较高级别的量子力学方法。

The results showed that hydrogen peroxide, silanols species and TiO〓 didn't have solvolysis activity of propylene oxide. While framework Al, coordinatively unsaturated Ti〓 ions as Lewis acid sites in the framework, Ti-OH and the five member ring active titanium species formed by TS-1, hydrogen peroxide and solvent can catalyze the solvolysis of propylene oxide.

研究结果表明：原料双氧水和TS-1沸石上的SiOH和TiO〓对环氧丙烷溶剂解反应无催化活性；而下列物种对环氧丙烷溶剂解反应具有催化活性：TS-1中的骨架铝，沸石骨架中配位不饱和的Ti〓形成的L酸中心，TS-1水解产生的钛羟基和由TS-1，双氧水和溶剂相互作用所生成的五元环中间活性钛物种。

The results showed that when the concentration of surfactant and metal ions (Cd2+) in the feed solution were 500 mg·L-1 and 10 mg·L-1,optimum conditions were air and liquid flow rates 100 L·h-1 and 5 L·h-1, liquid-and vapor-phase heights 45 cm and 66 cm,respectively,sparger (pore size 10 μm). Under the optimum conditions,the about 52% SDS and 99.35% Cd2+ were removed.

实验结果表明，当胶团强化超滤废水中初始SDS和Cd2+的浓度为1440 mg·L-1和50 mg·L-1时，排出的渗透液中含SDS和Cd2+浓度分别为500 mg·L-1和10 mg·L-1，在最佳的工艺条件下（曝气头孔径为10μm，空气流速为100L·h-1，液体流速为5L·h-1，泡沫高度为66cm，液面高度为45cm），SDS和Cd2+的去除率分别达52%和99.35%，SDS富集比为3.1。

A similar initiator, Et_2Zn/-Sparteine, yielded polys with threo-diisotactic -rich structure in the main chain, indicative of strongly asymmetric inducation in this system. In this case, no polymeric complexes in-site formed because of the intensive coordination between sparteine and Zn ions.The binary initiating system composed of Et_2Zn and n-BuLi combined the advantages of both metal alkyls, which gave the polymers with higher molecular weights and moderate optical activity ~(25_D =-97.1°～+24.3°.

Et_2Zn／n-BuLi二元引发体系综合了两种金属烷基化物的优点，得到了分子量相对较高(M_n=1.4x10~3～4.9×10~3)且含有手性超分子结构的光学活性聚合物；聚合物中锌含量的微小变化可引起聚合物光学活性明显改变，超分子手性与聚合物侧基的绝对构型存在关联。

The detector can realize imaging of very weak particle flow such as high-energy photons, electrons and ions flow, so it can be used for deep space exploration, spectral measurement, high-energy physics and bio-luminescence detection.

该探测器可以实现极微弱的高能光子、电子和离子等粒子流的成像探测，因此在深空探测、光谱测量、高能物理以及生物发光探测等方面将有重要的应用。

Objective: To establish the determination of copper ions by using spectrophotometric method.

目的：建立污染水中铜离子浓度分光光度法测定方法。

Objective To evaluate the methods and measurement conditions of the ultraviolet spectrophotometry for determination of iodine ions in drinking water.

目的 探讨应用紫外分光光度法测定饮用水中碘离子的方法及测量条件的选择。

The results show that the visible light response of the natural sphalerite sample results from the presence of substituting metal ions.

分析结果认为，天然内锌矿良好的可见光响应性能主要源自其晶格内丰富的类质同像替代离子。

The packing of spherical atoms of ions is one of the most fundamental structural patterns of nature.

球形原子或离子的堆积是自然界中一种最基本的结构模式。

These accelerated ions sputter material off the substrate as they hit its surface, as well as react with the substrate material.

这些加速的离子溅射关闭基板材料，因为它们触及其表面，以及反应的基底材料。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。

Designed by French fashion house Herm è s, this elegant uniform was manufactured in our home, Hong Kong, and was the first without a hat.

由著名品牌 Herm è s 设计，这件高贵的制服是香港本土制造，是我们第一套不配帽子的制服。
