| 摘 要： | 本文利用多项式插值法获得了铸造用砂的中间粒径、均匀度的近似求解公式、并且给出了计算框图。与通常利用描点作图来确定中间粒径、均匀度的方法比较,具有方法简便,能通过电子计算机快速、正确地求得结果,并且计算结果唯一等优点,因而具有一定的使用价值。利用多项式插值法也可以确定累积停留量曲线的分布系数。

| Abstract: | Using the method of the polynomial interpolation we get the approximate solution of middle diameter, uniformity of the foundry sand and .give out the flowchart.Compared with the usual method of through point construction to determine middle diameter and uniformity, this method has the following advantages: simplicity being able to use computers to calculate the result and the uniqueness of solution.The method of the polynomial interpolation can also be used to calculate distribution coefficient of sand cumulative curve. |
