The representative minority cultural relic-pottery relic of Buyi minority and the two wooden masks is taken as the research object. Firstly, Hiscanner laser scan detector was adapted for data collection, and then obtain point cloud data which could be recorded on disc for permanent saving was obtianed; Furthermore, the new popular reverse engineering software Geomagic for some disposals of point cloud data was adopted in data condensing, data mending, data filtering, feature line picking up to obtain NURBS surfaces; and then the error between the reconstructed CAD model and the point cloud data was evaluated to guarantee the precision of surface reconstruction to keep the relics keep its original appearance. In the end, the NURBS surfaces are imported to 3D software Solidworks and entities of CAD are generated by surface sewing, mold loft and ablating and other instructions.

选用有代表性的贵州少数民族文物―布依族酒壶、水壶以及木制傩戏面具作为研究对象，采用Hiscanner激光扫描测头对其进行数据采集，扫描得到的点云数据可刻录到光盘上作为文物数据永久保存；更进一步地，采用目前流行的逆向工程软件Geomagic studio对点云数据进行数据精简、数据滤波、数据修补、提取特征线等处理后得到NURBS曲面；为保证曲面模型重建的精度，在曲面重建模型后对其误差评价，通过控制误差的方式指导曲面模型重建，使重建的文物曲面模型能真实完整地反映原状；最后，在功能强大的三维造型软件Solidworks中导人重构的NURBS曲面进行曲面缝合、放样等，将其生成实体CAD模型，并对模型的局部特征进行适当的再设计以实现文物实体模型的优化。

In this dissertation, InGaAs/InGaAsP/InP MQW microdisk laser and its characterization were presented. Some conclusions are as following: the characteristics of lasing threshold was discussed by using rate equation. The dependent relations between threshold and cavity volume, spontaneous emission coupling efficiency β were investigated. The whispering gallery mode and spontaneous emission in a microdisk geometry were then studied. Almost all spontaneous emission was coupled into the lowest order TE mode when the normalized thickness of photonics well was between 0.15 and 0.5. The design principle and device process of InGaAs/InGaAsP/InP MQW microdisk laser were presented. The microdisk lasers with the diameter of 8μm, 4. 5μm and 2μm were succesfully fabricated by using etching techniques. The pulse lasing thresholds for the microdisk with the diameter of 8μm and 4. 5μm were 170μW and 15μW, a record results compared with the published in the literature. The cw lasing threshold for a 2-μm-diameter microdisk was only a few μW. We haven't found similar report up to now. To solve the problem of directional output in a microdisk laser, the power coupling efficiency in a double disk geometry was investigated with the theory of waveguide mode couple. A new structure of electrically pumped microdisk laser with output waveguide was designed, making a foundation for the practical use of microdisk laser.

该方法采用聚焦粒子束刻蚀和磁控溅射，可以获得可控的、干净的、无应力的纳米接触用于自旋极化探测。

"But there was a quality so much more terrible in the solemn mood of the popular mind, that she longed rather to behold all those rigid countenances contorted with scornful merriment, and herself the object."

但是，人们那种庄重的情绪反倒隐含着一种可做得多的气氛，使她宁可看到那一张张僵刻的面孔露出轻蔑的嬉笑来嘲弄她。

If the visible markings appear correct but the hidden engravings do not coincide with them, the lens is not correct.

如果可看见的标号看上去正确，但是暗藏的板刻与他们不相符，透镜不是正确的。

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

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。
