玻璃

Glass-powder early applied for chemistry industry in prosperous Tand dynasty , it only applied for ceramic and weapon according to history record, it apply for chemistry industry widely and applause due to raw material character diligency limpidity, no heavy metal, chemic and physical feature stabilization in modern times .

玻璃微粉最早应用于工业领域的是在盛唐时期，据史料记载，起初只限于陶瓷工艺品的应用和兵器制造。由于玻璃微粉原材料质地坚韧透明、不含重金属、化学物理性能稳定等特点，在现代化学工业中得以了广泛的应用和好评。

5 Wt% of P2O5 could give high content and prospecting SEM appearance of dental lithium disilicate glass-ceramic.

该玻璃体系中添加4.5 wt%的P2O5可以得到较高体积含量和理想显微结构的牙科二硅酸锂微晶玻璃。

Oweing to the suitable coefficient of thermal expansion and refractive index of lithium disilicate crystals, lithium disilicate glass-ceramics could obtain high mechanical strength and translucent effect simultaneously, which show a brilliant future in dental aesthetic restorations. The purpose of the study was to investigate the effects of glass composition, content of P2O5 and heat treatment procedures on microstructure and properties of final glass-ceramic products.

二硅酸锂晶体具有适宜的热膨胀系数和光折射系数，与玻璃相能够达到良好的热力学和光学匹配，使得二硅酸锂玻璃陶瓷在具备较高机械性能的同时，仍能保持优秀的半透光特性，实现了高强度和美学效果的统一，在全瓷美学修复领域具有广阔的应用前景。

All glass-ceramics with different compositions can have fine equiaxial crystalline microstructures and low thermal expansion coefficient.

玻璃的熔化温度和玻璃晶化峰温度及转变温度不断降低。

This β-eucryptite phase begins to dissolve at 1320℃ or above where the tielite (Al2TiO5) is apparently unstable and decomposed to corundum (Al2O3) and rutile (TiO2). Thirdly, in this dissertation, the influence of composition, crystallization temperature, and time on CTE were investigated detailedly.

然后，对制得微晶玻璃材料的热膨胀性能及力学性能与材料组成的关系，成核剂对玻璃析晶性能和膨胀系数的影响，以及晶化温度和时间的关系进行了分析。

Because of strong thermal expansion mismatch between the glass matrix and β-eucryptite phase in NEGC, the micro structure of the glass - ceramics changed (e.g. formation of microcracks) with the variation of temperature environmental,resulting in thermal hysteresis.

因锂铝矽酸盐负热膨胀系数玻璃陶瓷中之玻璃母相与β–eucryptite相之热失配效应过大，导致基材於升降温过程结构改变，所引发的热迟滞现象十分显著，其间接影响热补偿元件应用寿命，故本实验另一研究为观察此基材中迟滞现象的变化。

For example, glasses containing MgO where dolomite is cheaper than limestone, and low alumina glasses where feldspar or feldspathic sands are at a premium.

再举个例子，在白云石比石灰石廉价的地区出产的玻璃里会含MgO；在长石或长石质砂价格高涨的地区会出产低铝玻璃。

The hydrates of plain CAS glass are mainly gehlenite hydrate and CSH gel:and the preponderant hydrates or the mixture of CAS glass and gypsum are ettringite and CSH gel.

纯CAS玻璃相的水化产物主要为水化钙铝黄长石晶体和CSH凝胶：而掺有适量石膏的CAS玻璃相的水化产物则为钙矾石晶体和CSH凝胶。

Lucite and Plexiglas are trademarks used for glasslike acrylic materials.

卢西特和普列克斯玻璃是玻璃状丙烯酸材料的商标名。

This company uses from produces the high-quality sapphire raw material, main production: Upscale sapphire glass, Shan Qiao, Twinbridge, Shan Bo, double divination, plane, slot, aperture, handset surface Bolivia, mp3 surface Bolivia, mp4 surface Bolivia, three agglutination chips, calendar crystal, heteromorphous table mirror as well as laser infrared sapphire window glass, pressure transmitter window, precision instrument instrument element and so on. The design is diverse, by the fine product, the price which most gives preferential benefit, provides the high quality at low price for the customer the commodity.

本公司采用自产高级蓝宝石原材料，主要生产：高档蓝宝石玻璃、单桥、双桥、单卜、双卜、平面、开槽、开口、手机面玻、mp3面玻、mp4面玻、三件粘合晶片、日历晶、异形表镜以及激光红外线蓝宝石窗口玻璃，压力传感器窗口、精密仪器仪表元件等。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
