The ion-doped crystals have such performance as schillerization ,up-conversion and tunable laser,etc.

ZnWO4单晶是一种优良的基质晶体材料，过渡金属离子和稀土离子能够较容易地掺杂进去，从而使掺杂ZnWO4晶体具有闪烁发光、上转换发光、可调谐激光等性能。

Our method provides a flexible means to control the ion current which has been very difficult to do. A lower current also reduces the requirement on the power supply as well as other instrumental concerns such as secondary electron emission and x-ray shielding, both of which are very serious for high-voltage implantation.

我们的方法提供了一个简易可行的控制离子电流的手段，较低的离子电流对负高压功率要求降低，同时也减低了对二次电子发射和x射线屏蔽的要求，这在高电压注入中尤为突出。

By a theoretical model, influences from electron temperature, ion temperature, plasma flow and secondary electron emission are mainly analyzed.

主要讨论了电子温度、离子温度、等离子体流动以及二次电子发射对尘埃带电的影响；数值计算研究了尘埃带电的弛豫时间；在考虑了离子拖拽力作用下，估算了尘埃粒子在聚变装置中的运动速度；针对碳材料的尘埃理论计算得到了粒子的寿命。

The amount of oxygen in the recording layer is substantially greater than the amount required for the stoichiometric oxide or oxides of the segregant or segregants, and a substantial portion of the oxygen present in the recording layer is present in the inter-granular material.

记录层中的氧的量显著大于分离子或多种分离子的化学计量氧化物或多种氧化物所需的量，出现在记录层中的氧的主要部分存在于颗粒间材料中。

Contaminant cations such as calcium,magnesium,barium,strontium,and radium and anions such as fluoride ,nitrate,fulvates,humates,arsenate,selenate,chromate ,and anioic complexs of uranium can be removed from water by using ion exchange or adsoption onto activiated alumina.

具有污染能力的像Ca，Mg，Ba，Sr，Ra的阳离子，和像氟化物，硝化物，黄酸物，腐质酸物，砷酸盐，硒酸盐和铬酸盐的负离子以及像铀一样的负离子复合物可以通过离子交换和离子吸附从水中排除。

Transport properties including the coefficients of self-diffusion, viscosities, and conductivities were also studied and compared.

In the first part, two novel methods were proposed for the determination of three kinds of organogermanium compounds βcarboxyethylgermanium sesquioxide,β- carboxyethylgermanium sesquioxide and di-(β-carboxyethyl) germanium hydroxide by using high performance ion-exchange and ion-exclusion chromatography.

第一部分采用高效离子交换和离子排斥色谱法，建立了两种测定三种有机锗化合物β-羧乙基锗倍半氧化物、β-羧乙基锗倍半氧化物、二-锗氢氧化物的新方法。

The results indicate that it is possible to identify and distinguish these siccative oils because the unsaturated acid had changed into azelaic due to oxidation and polymerization during the drying process to make the chromatogram of siccative oils have a typical peak of C9 compound and provide a finger marker of m/z 217, and the concentration ratio of palmitic acid to stearic acid remains constant with time to facilitate the differentiation of oils.

分析时采用了热裂解与甲基化同时进行的技术。分析结果显示，4种干性油的不饱和脂肪酸在成膜后的甲基化产物均为壬二酸二甲酯，离子质量与离子电荷量比值为217，是干性油的特征检测峰。4种油中不同含量的软脂酸和硬脂酸在干性油成膜前后的比值不变，为干性油的甄别提供了可能性。
