量提计量检定规程JJG19—85规定:量提内径与深度的比例应在1比1至1比1.3之间。这条规定是较为合理的,至少有三点好处:①因为高(深度)与内径尺寸几乎相同(可稍高些),这样在使用量提时,较为方便;②比较节约原材料,给制造者带来一定的效益;③减小使用误差。对于第一点是显而易见的。对于第二点,根据数学推导,可知当圆椎形体积一定时,深 Volumetric measurement test procedures JJG19-85 states: the amount of reference to the ratio of diameter and depth should be between 1 to 1 to 1 to 1.3. This provision is more reasonable, with at least three advantages: ① Because the height (depth) and the inner diameter of the same size (may be slightly higher), so that the use of time is more convenient; ② more economical raw materials, to the manufacturer with To certain benefits; ③ reduce the use of error. For the first point it is obvious. For the second point, according to mathematical deduction, we can see that when the cone-shaped volume is constant, deep
