In a preceding paper with the same title the result was represented by curves which enable factors used in calculating the true diameter to be determined. Instead of the curves a quadratic equation is used to produce the same factors. The data for the equation are given in two tables.
在一篇标题相同的前文里,结果是用曲线表示的,这些曲线能确定用于计算真实直径的因子。现在用一个二次方程来代替这些曲线以得出相同的因子。方程的数据列在两个表格中。
