表面切割

Linen also comes in varied quality and weight, has a finer and smoother texture than cotton, and unprimed linen is light brown in color. I prefer the surface of linen for painting, however, it is more expensive. If you plan to do more than a few paintings, it is usually better to buy a larger piece of canvas, since less will be wasted with a larger piece when cutting for various canvas sizes. You can find fabric canvas, and panels and pre-stretched canvases in art stores, and some office supply stores and department stores carry canvas panels and pre-stretched canvases.

床单也丰富多彩的质量和重量，有一个更精细和平滑纹理比棉， unprimed亚麻是浅棕色的颜色，我喜欢表面上的麻布画，却是更昂贵的，如果您打算做多过几个画，它通常不如买一个大尺寸的油画，自少被浪费了一个更大的片切割时，由于种种画布大小，你可以找到面料帆布，和小组预拉伸画布在美术商店，及一些办公用品商店及百货公司进行帆布板和预拉伸画布。

Methods Based on thin layer CT mandible image data and the USIS software by ourselves, the individual geometry of the complete range of mandible was well established, also the distinction between the contour boundary of cortical and cancellous bones was done automatically. A series of new effective CAD methods such as "no-seed region segmentation", non-parallel "best cross-section planes" and the algorithm employed a pair of B-spline curves fitting were used to accurately construct of 3D geometry surface model of the complete range of mandible in a man-machine conversation and automatic style.

利用CT薄层扫描下颌骨获取的断层图像数据，在自主开发的USIS软件的基础上，自动分辨骨皮质和骨松质轮廓边界，并对下颌骨采用"非种子区域分割"、非平行"最佳切割曲面"及"B样条曲线拟合法"一系列新型CAD方法进行人机对话自动重建精确的几何表面模型。
