摘　　要：首先简要介绍了圆周率的计算发展历史。其次通过归类分析的方法将圆周率在社会生活中的应用分为以下几个方面:计算机领域、数学和人的记忆以及数学水平高低的判断标准等,得出π是衡量计算机各项指标与实用前检验的最佳手段,是检验计算圆周率公式优劣的最好方法和人类记忆移植实验成功与否的检验也需要圆周率的结论。还论述了背诵圆周率能够培养人的记忆能力。介绍了人们在记忆圆周率时所发现的一系列记忆数字的新方法以及现代人们把圆周率近似程度的高低作为衡量一个国家数学水平的判断标准。充分说明了圆周率在社会生活中的广泛应用,体现了圆周率真正的价值。The computation development history of the is briefly introduced first in this article.Next,the applications of π the π in the social life are divided into following several big aspects by the classification analysis method： computer domain,mathematics,human＇s memory and the judgment standard of the mathematics level and so on.The conclusions that the π is the best method to weigh each computer target and to examine it before practical,it is the best method to examine the formula of computation and the human＇s memory transplantation tests successful or not also needs the π are obtained.Reciting the π could raise human＇s memory ability is discussed.A series of new methods how to remember numbers are discovered when the π is memorized.The approach level of the π is looked as the judgment standard to weigh a national mathematics level by modern people.The widespread applications of in social life are showed fully and the real value of girth quotient is reflected.
