球体积的计算在微积分创立之前,是一个十分困难的问题。然而,在古代中国、印度和日本等地都先后导出了正确的球体积计算公式。对上述这些地区发现和证明球体积公式的方法、思想和途径进行比较分析,不仅有助于深刻理解不同文明或地区的数学传统,而且有助于揭示数学在不同地区之间的交流与传播的途径和线索。
Calculation of the ball volume before the creation of calculus is a very difficult problem.However,in ancient China,India and Japan,the correct formula for calculating the volume of the ball have been derived.Therefore,for these areas,the comparative analysis of the methods and thoughts and means that have discovered and proved the equation of ball volume calculation was carried out.It not only contributes to a profound understanding of different cultures or regions of traditional math,but also helps to reveal the math exchanges between different regions and the mode of transmission and clues.
