摘　　要：根据巴西生产的圆孔定量板，对其中央孔形状和容积进行3次改进。第一次改进为椭圆形孔定量板，容积为38．59mm^3；第二次改进后定量板容积为38．70mm^3；第三次改进设计了圆台形孔定量板，容积为38．701mmm^3改进后的定量板不仅与圆孔定量板的容积一致，而且在操作中粪样较易通过定量板板孔，减少了粪量误差，提高了准确性。On the basis of template with rotundum made by Brazil, we modified the sharp of the hole in the template thrice. Thrice modifications have been applied. The hole was modified into oval shape with a volume of 38.59 mm3 during the first modification. Then, the volume was changed into 38.70 mm3 during the second modification. In the third modification, the hole was changed into round shape with bigger diameter at the bottom, of which the volume was also 38.70 mm3. After modification, the volume of the modified hole is the same as that of the rotundum in the template and the stool is easier to pass through the hole which raises accuracy.
