摘　　要：通过圆锥体的锥度与锥角间的函数关系,推导出测量圆锥体时,正弦规的量块组尺寸计算公式和圆锥角的精密简便测量方法。量块组尺寸计算公式不含三角函数,计算简便、结果精确,特别适合车间现场使用。A formula for calculation of the size of the sine protractor measuring blocks and an easy way to accurate measurement of conical angle is deprived by the function relation between taper and taper angle. As no trigonometric function in the formula results in easy and accurate calculation result, it is especially suitable for workshop applications.
