摘要
通过对厦门某日室外逐时干球温度数据组的拟合公式比较,得出高斯多峰函数的拟合精度高于傅立叶级数三角函数.在此基础上,采用高斯多峰函数对厦门年逐时室外空气干球温度进行多峰拟合,得出拟合公式,其拟合的可信度为99.5%,0.5%的拟合值与实际值相差较大,误差在±2℃范围内.
The paper compared the fitting formulas of hourly outdoor air drybulb temperature in Xiamen.And found that the fitting precision of the multi-peak Gaussian fitting function was better than the conclusions of trigonometric Fourier series,Based on this the paper used Gaussian function in Xiamen years of hourly outdoor air dry-bulb temperature of multi-peak fitting,and obtained fitting formulas,The credibility of the fitting was 99.5 %,0.5 % of the fitted value differed from the actual value with an error range of ±2 ℃.
