| 摘 要： | 圆周率π自古以来一直是人们日常生活中的一个非常重要的常数,祖冲之是我国古代杰出的数学家,在圆周率的研究上为人类作出了不朽的贡献,求出了约率22/7和密率355/113,已非常精确。这一结果是如何推算的一直为人们所考究,笔者就此作些尝试。

| Abstract: | Circumference ratio is a very important constant in our everyday life from everlasting.Zu Chongzhi is a great ancient mathematician in our country and his study of circumference ratio is immortal contribution to mankind.The approximately leads 22/7 and asymptotic density 355/113 he worked out had already been accurate,but how he calculated it? In this paper,the author tries to conjecture the calculating method. |
