玻璃

In this paper, we introduce the optical electronegativity Dwglass, to predict basic properties of binary oxide glasses (phosphate, borate, silicate, germinate, tellurite, and titanate).

在本文中，我们引入光学电 DW的玻璃，预测的基本性质二元氧化物玻璃（磷酸盐，硼酸盐，硅酸盐，发芽，碲，钛酸）。

What these three edifices manifest is "concrete-form imagery": The most eye-catching feature of the Grand Louvre expansion project is I.M. Pei's glass pyramid, employing modern-day materials to manifest anew the dream of the ancient Egyptians, to transcend mundane existence and to enter into a heavenlyparadise beyond the influence of events in time and space and not subject to natural deterioration; the four-sided La Defense Arch symbolizes a window "opened to the world and welcoming the future"; and the French National Library's four L-shaped glass-walled towers concretely represent opened books standingon end, giving the viewer the immediate impression of "book."

这三件建筑作品呈现的都是「具支配之世外桃源的古老梦想；拉德芳斯凯旋门象徵「一扇开向世界、迎向未来」像的意象」：大罗浮宫计画中最受注目的，是贝聿铭的玻璃帷幕金字塔，使用现代材料重现埃及民族渴望超脱其生存的现世，进入一个不受时间与自然毁坏法则的窗子；国家图书馆则以四座L型玻璃帷幕高塔，具体表现出四本打开立放的书，直接传递「书」的立即印象。

Compared with other wave-guide material, glass is not so good on the thermal conduction, and its transmission loss is bigger, but it is easy for processing, especially the wave-guide surface can have much higher degree of finish.

虽然玻璃较其它波导材料导热性能较差、传输损耗较大，但由于易加工，尤其是波导面可达到很高的光洁度，且价格低廉，因此硬质玻璃波导CO_2激光器仍具有很高的实用价值。

In the production process of glass,the thickness of glass is directly related to the product quality.

在玻璃的生产过程中，玻璃的厚度是否均匀直接关系到产品的质量。

Place filter paper (150mm×150mm)with test piece on the glass plate, inject tinct water into glass tube and check filter paper after 24 hours.

将圆形玻璃管垂直放在试件穿孔试验点的中心，用密封胶密封玻璃管与试件间的缝隙。

Class sunroof and stern port are equipped with special suntan class to release passenger from ultraviolet radiation and torridity.

In the review, the theory of glass transition and dynamics were introduced. The relation between glass transition and function in cereal food was discussed.

介绍了玻璃化转变的基础理论及动力学，论述了谷物食品体系中玻璃化转变与其功能之间的关系。

The internal skin is a layer of rotate-able white translucent screens. When the screen is rotate to the position perpendicular to the facade, the panoramic lake-view enters the dining space; when closed, the dining room has both proper natural light and privacy. The glass boxes would look like white lanterns floating on the lake, as the interior lighting is softly diffused by the screen.

外层为Low-E中空玻璃幕墙，设有电动开启扇；内层为可透气的中转白色轻纱屏风，可开可闭：开启时，湖面的景色被毫无阻隔地引进室内的用餐空间；闭合时，用餐空间可拥有私密性，同时不影响采光；若在夜晚，室内的灯光通过轻纱发生漫射，水面上的玻璃盒子有如漂浮的纸灯笼。

The fabrication of transmission gratings with the grating constant of 2.5μm and 5μm is studied in ZK6 and LaF2 glasses at the machining speed of 400μm/s by using femtoscond laser with the peak intensity of 2.7×10~(13)W/cm~2, and the diffraction patterns of the grating are presented with a semiconductors laser at 650 nm.

在加工速度为400μm/s、激光的峰值功率密度为2.7×10~(13)W/cm~2时，在ZK6玻璃和LaF2玻璃内制备出光栅常数为2.5μm和5μm的透射式衍射光栅，并在650nm的半导体激光照射下获得了光栅的衍射图样。

"A glass door? What do you expect us to do with a glass door, tubercle?"

"一扇玻璃门，你那玻璃门顶什么用啊，小土豆儿？"
