There were only three glasses; the water was so dirty that there was no telling whether the tea were strong or weak, and the samovar would only hold water enough for six glasses. But that made it all the more fun to take turns in order of seniority to receive a glass from the plump, short-nailed, and not over clean fingers of Marya Hendrihovna.

It's because those glasses don't look right on your face, you have a long face and those glasses make you look shifty.

因为那副眼镜和你的脸根本就不合适，你有一张长脸和可是那副眼镜会把你改变了。

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 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。

So these tellurite glasses may be good candidates for broadband optical window material.Different concentration rare earth ions doped different kinds of tellurite glasses have been done in our experiment.

透过光谱的结果表明这两个体系玻璃的光透过率较高，而且紫外吸收截止边较短，具有宽的透过窗口。

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。

Apart from this polarizing feature, these glasses serve the same purposes as any dark glasses, absorbing 50% of the incident light; in an unpolarized beam, half the light can be considered as polarized horizontally and half vertically, and only the vertically polarized light is transmitted.

除偏振特色之外，为了同一目的，眼镜可以做成暗色，50%的入射光可以被吸收；在非偏振的入射光，有一半可以认为是水平偏振，另一半认为竖直偏振的。这样仅有竖直偏振光可以传播。

Finally it offers the analysis of the fault-tolerance system as well as its test verification.

这样，运行于空间环境中的系统的设计目标就是在保证系统实时性

However, it is still difficult to find out the real reason of the increase of the keratinized gingiva during the orthodontic extrusion whether it is due to the proliferation of the gingival tissue or to its elastic nature, that is because the proliferation of the fibroblasts as well as the connective tissue changes in volume and the intra-fibers spaces were all immeasurable in most of the studies.

然而，仍然难以找到真正的原因增加的角化牙龈在正畸挤压它是否是由于扩散的牙龈组织或其弹性性质，这是因为增殖的成纤维细胞以及作为结缔组织的变化量和内部纤维空格都是不可估量的，大多数的研究。
