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.

前言 考古绘图一直是考古学研究中不可或缺的重要技术,能够反映考古遗迹的分布状况或者典型器物的多重特征。但是随着考古学研究的深入和对相关技术手段需求的增加,考古绘图技术却始终停留在通过直尺等量取数据、再使用直尺和铅笔绘图的水平上,成图精度很低,周期较长,图形品种单一,远远不能满足现代考古学研究的需要。

By the Test, we find out the better technological conditions, the results show that the secondary magnetic-spiral and spiral -magnetic are the better flowsheet for the pyrite cinders. Under the action of muriatic acid and hydrofluoric acid, the content of sulphur, silicon, lead, copper are descend to 0.21%, 8.26%, 0.053%, 0.023%. A total iron concentrate containing 62.34% Fe is obtained with recovery of 78.08% Fe.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
