Results Sandblasting changed the glass infiltrated alumina surface more obviously than etching, the volume losing of glass infiltrated alumina was much smaller than that of Vita Mark ⅱ. 结果喷砂对氧化铝玻璃渗透陶瓷表面结构改变大,氧化铝玻璃渗透陶瓷体积丧失量小于VITAMARKⅡ。
And then the paper studied the recognition about volume equipment and file encryption mark processing in the file system filter driver, and realizes file dynamic encryption and decryption module. 文章深入分析文件过滤驱动对卷设备的识别和对文件加密标记的处理,实现了对文件的动态加解密。
This algorithm only needs to render data once, and realizes concave clipping. ( 6) In order to realize better interactivity in the course of cutting operation, a cutting algorithm base on volume mark is presented. 该算法只需绘制体数据一次,并可实现凹体切割。(6)为了在切割操作中获得更好的交互性,提出一种基于体标记的切割算法。
Under the premise of formation craft analysis, take the volume shrinkage, the shape distortion, the fusion mark, the air bubble and the packing time as the goal, carried on the best runner position analysis, the flow analysis and the cooling analysis. 在分析成型工艺的前提下,以体积收缩率、翘曲变形、熔接痕、气泡及填充时间等为目标,进行了最佳浇口位置分析、流动分析和冷却分析。
