摘　　要：探讨了在正弦规上测量圆锥(台)体角度的方法,并推导了相应的计算公式;将推导公式与手册给出的公式进行了比较,说明使用手册给出的公式计算存在局限性;通过一个测量实例,得出当斜角大于7°时,应使用本文推导的公式进行计算较为准确。The method of measuring cone angle on sine protractor is discussed,and the corresponding calculation formula is deduced.The deduced formula is compared to the formula given in the handbook.It is indicated that the formula given in the handbook has limitation.It is shown by a measurement example that using the deduced formula in calculation can give more accurate result when the bevel is bigger than 7°.
