摘　　要：级数的出现源于生产实际,反之级数也在实际中存在巨大的应用空间。本文探究了级数在数学和其他领域的应用,首先利用级数理论将复杂的求极限、近似计算等问题转化为简单的级数问题。其次,重点研究了级数在生物领域的应用,探讨级数在预测新冠肺炎确诊病例数问题中的应用,并利用麦克劳林级数提出一种新的生物节律估算方法。The emergence of series comes from the actual production, and conversely, series also has a huge application space in practice. This paper explores the applications of series in mathematics and other fields. Firstly, the problems of complex limit calculations and approximate calculations are transformed into simple series problems by using series theory. Secondly, it focuses on the applications of series in the field of biology, discusses the application of series in predicting the number of confirmed cases of COVID-19, and puts forward a new method for estimating biorhythm by using McLaughlin series.

关 键 词：级数 极限 近似计算 定积分 生物节律
