玻璃

Last winter, when we had many very clear nights, Victor spent hours in our bedroom, using a compass and straightedge, and scarring the glass with a glass cutter to make a star dial for us.

上个冬天，很多天气特别晴朗的夜晚，维克托都会呆在我们卧室里几个小时，用指南针，尺子和玻璃刀在玻璃上为我们画出一个星晷。

The series are using for flat glass grinding, and parallel straightline rough grinding,fine grinding and polishing finishing atone time.

该系列产品适用于对平板玻璃的磨边加工，对玻璃的直线圆弧边的粗磨、精磨或抛光一次加工完成。

A stumper with required structures is pressed into the surface of polymeric foil and heated to a temperature above its glass transition temperature under suitable pressure until the temperature droped below the glass transition temperature of the polymer, followed by removal of the stumper and left the structures of the stamper in the polymeric foil.

将聚合物加热到其玻璃转化温度以上，利用预先制备好的模板在适当的压力下压向聚合物样品，保持压力直到聚合物温度降到玻璃转化温度以下，将模板移去后，模板上图形便转移到样品表面。

Not only with glass but now also with plastic the Group is today able to cover practically all requirement fields to a high standard in addition to glass flacons and pots for fine fragrances, deodorants, creams, etc., the product range offers flexible bottles and vials for shampoos, shower gels and sun cream for example.

不仅与玻璃，但现在还用塑料集团今天能够覆盖几乎所有领域的要求，高标准，除了玻璃flacons和罚款香水，除臭剂盆-，奶油等，产品系列优惠和灵活的瓶小瓶的洗发水，沐浴凝胶，例如防晒霜。

Then we test the density, transmittance properties of these tellurite glasses. The result shows that these glasses\' density is 2～3 times of that of silica and UV cut-off wavelength is quite short.

然后又研究了Na_2O-TeO_2-WO_3-Al_2O_3和TeO_2-TiO_2-La_2O_3碲酸盐玻璃的形成与性能，研究表明，这两个体系玻璃的Tg和Tx-Tg的综合性能较好，具有良好的工艺性。

The results indicate that in Er3+-doped niobic tellurite glasses, proper amount of B2O3 can be used as a mo-difier to improve thermal stability and spectroscopic properties of Er3+ ions.

结果表明，在掺铒碲铌玻璃中，适量的B2O3能较好地提高玻璃的热稳定性能和Er3+离子的光谱性质。

The Raman and infrared spectra of tellurite glasses were studied, and the influence mechanism of OH- on upconversion luminescence of Er3+-doped tellurite glasses was analyzed.

研究了碲酸盐玻璃的拉曼光谱和红外光谱，分析了OH-对掺Er3+碲酸盐玻璃上转换发光的影响机制。

In this paper, first, we analyse the glass forming ability by theoretic method and experiment. Then we have the glass forming zone by experiment for our research\'s convenience. In this zone, we have detrail research on the Na_2O-TeO_2-WO_3 glasses and analyse the microstructure, raman spectra, thermal stability, crystallization of the tellurite glasses.

本文首先以玻璃形成理论为基础，分析了碲酸盐体系的成玻性能，并通过实验研究，确定了Na_2O-TeO_2-WO_3体系的成玻范围，研究了该体系玻璃的微观结构、热性能和析晶性能等。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。

The factory affiliated to the Group primarily manufactures multiple-purpose pincers, baking kits, knives, scissors, kitchenware, gardening tools and beauty care kits as well as other hardware tools, the annual production value of which reaches US$ 30 million dollars.

集团所属工厂主要生产多用钳、烤具、刀具、剪刀、厨具、花园工具、美容套等五金产品，年生产总值3000万美元，产品价廉物美、选料上乘、质量保证，深受国内外客户的青睐
