本文第一部分介绍了“咬冰角”的标准参数,该参数将冰刀按几何形状要求进行了合理的分类(弄清了各类冰刀咬冰角的大小及其变动范围,说明咬冰角的变化随刀沟半径及刀身厚度而变化).第二部分是说,所用咬冰角参数值相同,又如何来估价磨刀的效果.尚未阐明的是,为什么学校用的初级花样刀和实际比赛用刀的 The first part of this article introduced the standard parameters of “biting ice horn”, which makes reasonable classification of ice skates according to the requirements of geometry (clarify the size and scope of various types of ice bites and indicate the bite angle Of the change with the knife groove radius and blade thickness and the change.) The second part is that the binging horn parameters used are the same, how to evaluate the effect of sharpening.Unless to clarify why the school primary knife and the actual Game with a knife
