摘　　要：本文在余弦函数模拟气温的基础上,提出傅里叶级数法,并选取我国北方和南方某工程的气温资料,采用两种方法进行模拟对比分析。结果表明,傅里叶级数法模拟的温度与实际温度拟合较好、精度较高,该方法对大体积混凝温控计算方面具有很大的借鉴意义和应用前景。On the basis of Cosine Function simulation of air temperature,Fourier Series Method is proposed in this paper,and the temperature data of a project in north and south China are selected to simulate and compare the two methods.The results show that the temperature simulated by Fourier Series Method fits the actual temperature well and has high precision.The method has great reference significance and application prospect in the temperature control calculation of mass coagulation.
