This article outlines the progress of ancient Chinese lenses from the Pre-Qin Period to the Five Dynasties, and discusses mainly two arguments: First, the"yangsui" recorded and narrated in Lun Heng by Wang Chong of Eastern Han Dynasty may be a plano-convex glass lens; secondly, the"four mirrors" recorded and narrated in Tanzi Hua Shu by Tan Qiao of Southern Tang Dynasty may be a plano-convex lens, a biconvex lens, a transparent planeparallel plate and a concave-convex lens respectively, but what kind of tra...

本文概述了中国古代透镜从先秦到五代的发展进程，着重从古代文献和出土文物的研究出发，结合中国古代社会经济发展水平，论证了东汉王充《论衡》中记述的阳燧可能是玻璃平凸透镜；论证了南唐谭峭的《谭子化书》中记述的"四镜"可能是平凸透镜、双凸透镜、平光镜和凹凸透镜。作者认为《谭子化书》"四镜"段可能实际上是对中国古代透镜发展的阶段性总结。

CeO2 is a cheap and of use wide material, it is used in optical materials. polishing agents. ultraviolet absorption materials. the cleaning catalyst of car waste gases. chemical decolorant of glass. radiation-resisting glass. permanent magnet. electronic ceramics etc. After it becomes nanoparticle, it will show some new properties and applications. For example, CeO2 nanocrystal is a better promoter of Cytochrome C and the stabilizer of Zr02 ceramics.

CeO_2是一种廉价而用途极广的材料，如用于发光材料、抛光剂、紫外吸收材料、汽车尾气净化催化剂、玻璃的化学脱色剂、耐辐射玻璃、永磁体、电子陶瓷等，纳米化后将出现一些新的性质及应用，如CeO_2纳米晶是细胞色素C的良好的促进剂，还用于ZrO_2陶瓷的稳定剂。

CeO_2是一种廉价而用途极广的材料，如用于发光材料、抛光剂、紫外吸收材料、汽车尾气净化催化剂、玻璃的化学退色剂、耐辐射玻璃、永磁体、电子陶瓷等，其纳米化后将出现一些新的性质及应用，如ceOZ纳米晶是细胞色素C的良好的催进剂，还用作zro：陶瓷的稳定剂，由于ceo：折射率高，稳定性好，常用于制备减反射膜等。

The results shows that all these elements are enriched in the glass phase except for Al and Mn, and all the elements are depleted in the mullite-corundum phase except for Al.The iron group elementsand the ore-forming metalsare enriched in the ferruginous spheres, but the rest elements are depleted.

结果表明，除Al、Mn外，其他元素均在玻璃相中有不同程度的富集；除Al外，其他元素则在莫来石-刚玉相中有不同程度的贫化；除Ti以外的铁族元素以及除Ga、Pb以外的金属成矿元素均在铁质微珠中富集，其他元素则在其中贫化。

Glass ceramics with α cordierite(2MgO·2Al 2O 3·5SiO 2) as main crystal phase, having excellent dielectric property, are perfect materials for microwave parts of a medium apparatus However, the thermal expansion coefficient of the material is not high enough for some special applications Now, a novel glass ceramics with suitable thermal expansion coefficient (47 7×10 -7 / C) and excellent dielectric property (ε=5 1,tgδ0 -3 ) was developed Crystallization process and the th...

本文以堇青石微晶玻璃为研究对象，首次研制得到了一种低介（ε＝ 51）、低损耗（tgδ＜10－ 3）、热膨胀系数（46 ～48 ×10－ 7' C）能与其它器件相匹配的新型微晶玻璃介质材料通过 X射线衍射分析，扫描电镜观察等测试手段，研究了该材料的晶化过程和热膨胀系数的变化规律发现样品的热膨胀系数随温度的变化行为是与样品中析出的晶相种类及析出量随温度的变化规律相对应的

Moreover,phase separation of glass was promoted by introduction of TiO2,therefore nucleation and crystallization were improved.

而且TiO2的引入，还有利于玻璃的分相，进一步促进了系统的核化和晶化。

With the increase of steel slag , the nucleation and crystallization temperature decrease and pyroxene crystalline become more according to the result of XRD .

随着钢渣引入量的增加，玻璃的核化温度和晶化温度均降低，材料中辉石类晶体的析出相应增加。

Currently, the main opacifier is zircon. Zircon crystals which formed in vitrified tiles have different refractive with glass caused light scattering, it makes vitrified tiles whiteness.

目前，玻化砖中乳浊剂主要采用的是锆英石，其增白机理是在玻化砖中形成硅酸锆晶体，利用硅酸锆晶体与玻璃相之间的折射率差使可见光发生散射，从而产生增白效果。

We transfer the taken picture into binary form and separate scratches and dusts by calculating their areas.

取像后，使用二值化加强刮痕影像，再利用二值化图形中面积的大小进行刮痕与灰尘的分类，藉此来检测出玻璃基板上的刮痕。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
