The matrix composites for diamond tools were tested with such modern testing instruments and equipments as DTA-7 differential thermal analyzer, JCXA-733 electronic probe and scanning electron microscope, JEM 2000 FX Ⅱ transmission electron microscope, eXL energy spectrometer, and humidity test instrument. The analysis, comparison, and induction of the testing results prove the enhancing effects of the rare earth on the matrix composites: degeneration, micro-alloying, purification, and catalytic activation. The comprehensive function of these effects leads to the decrease in the porosity of the matrix composites and to the increase in such actual indexes as the flexural strength, hardness, and impact ductility of the whole rare earth Fe-based diamond tool materials.

The surface representation in discrete form and its differential computation are important issues in computer graphics and geometric design.

0引言一般来说，曲面的一阶微分量是指曲面的切平面方向和法向量，二阶微分量是指曲面的曲率等有关量·它们作为重要的曲面信息度量指标，在计算机图形学，机器人视觉和计算机辅助设计等领域发挥了重要的作用·传统的曲面是连续形式的参数曲面和隐式曲面，其微分量的计算已经有了较完备的方法·随着激光测距扫描等三维数据采样技术和硬件设备的长足进步，以及图形工业对任意拓扑结构光滑曲面造型的需求日益迫切，离散形式的曲面———细分曲面、网格曲面和点云曲面正在逐渐成为计算机图形学和几何设计领域的新宠·于是，对这种离散形式的曲面如何估
