    • A method for processing three-dimensional shape data includes steps of obtaining a plurality of point data along a surface of an object having a three-dimensional shape; taking out a point data from the obtained point data to be processed, approximating each specified number of point data in the to-be-processed point data adjacent the taken-out point data by a polynomial and then finding two unit vectors at the taken-out point data; finding an opening angle defined between the two found unit vectors; comparing the found opening angle with a predetermined threshold value of the opening angle, determining whether or not the found opening angle is not larger than the threshold value, and thinning the taken-out point data when the found opening angle is larger than the threshold value and not storing the taken-out point data in a storage unit, and leaving the taken-out point data without the thinning when the found opening angle is not larger than the threshold value and storing the taken-out point data in the storage unit.
    • 一种处理三维形状数据的方法包括沿着具有三维形状的物体的表面获得多个点数据的步骤; 从所获得的待处理点数据中取出点数据,通过多项式近似在取出点数据附近的待处理点数据中的每个指定数量的点数据,然后在采集点处找到两个单位向量, 出点数据; 找到在两个找到的单位向量之间定义的打开角度; 将所述发现的开度角与所述开启角度的预定阈值进行比较,确定所述求出的开度角是否不大于所述阈值,以及当所述求出的开度角大于所述阈值时,使所述取出点数据变薄 并且不将所取出的点数据存储在存储单元中,并且当所述发现的开启角度不大于所述阈值并且将所述取出点数据存储在所述存储单元中时,保留所述取出点数据而不变稀。

    • An ion-exchange membrane method electrolytic cell comprising a coil cushion arranged between a conductive plate and a cathode in a cathode chamber, and further an ion-exchange membrane arranged in contact with the cathode. The conductive plate is not perforated, and the coil cushion is arranged so that its axial direction is in agreement with the vertical direction of electrolytic cell. Preferably the coil cushion is made of a metal coil and has an impact resilience of 7-17 kPa. The cathode preferably has supported electrode catalyst and is made of an expanded metal with strands of 0.1-1.0 mm width and 0.1-1.0 mm thickness, and having SW of 0.5-5.0 mm and LW of 1.0-10 mm, and 48-60% open area. The electrolytic cell is energy-saving, and damage thereof can be avoided over a long period, and elevation of voltage and reduction of current efficiency with time can be minimized.
