摘要
采用修正椭球的方法,逼真地描绘出了种蛋的几何外形,并推导出了表面积和体积的解析公式。简单测量种蛋的几何尺寸,便能求得表面积和体积的数值。通过模拟图形与照片的比对,发现在几何特征上拟合效果良好。测算得到的体积,与溢水法测得的体积相比,误差小于千分之五。
In this paper,the geometric shape of the egg is vividly depicted with the method of modifying ellipsoid,and the analytical formulas of surface area and volume is derived. Values of surface area and volume can be obtained after easy measurement of the egg size. By collating the graphic with photo,it can be confirmed that they match well. And comparing with the volume of overflow,the result shows that the error is less than five thousandths.
