等高线图上估算容积体积公式的改进

Modified formula for volume or bulk estimation by contour diagram

分析了用Бауман公式计算容积体积存在的不足之处 ,提出改进公式 。

We analyse the deficiency the Бауман formula to calculate volume or bulk by contour diagram and introduce another simple and direct formula. A method to draw the middle cross section is also deduced.
