| 摘 要： | 采用文献资料调研、实验检验、几何证明等方法，对检测速滑刀弧度结果不能反映刀弧真实形状的原因展开商榷，分析以固定基准检测速滑刀弧度结果能够反映刀弧真实形状的理论与实验依据。将检测速滑刀弧度的基准触点置于刀刃底面，会因两处基准触点下的刀刃底面被磨削而使测量基准位置发生改变，所测得的弧度结果不能反映出刀弧的真实形状；以固定基准检测速滑刀弧度，刀弧距离测量基准的变量是刀刃底面的实际被磨削量，研磨速滑刀前、后所测得的弧度值能够反映出刀弧度的真实形状。

| Abstract: | By using the method of documentary investigation,experimental testing and geometric proof,the author finds that if put datum point of checking speed skate is on the edge of skate,it makes measurement basis change,the result of radian measured can not reflect real curve shape.Curve speed skate checked by fix datum basis,variable of measure basis with distance of curve actuality ground tolerance for tolerance for the edge of skate,measured curve value reflects real curve shape. |
