摘　　要：针对简化太阳位置算法的拟合特点,开展算法的对比模型及应用研究。模型涉及"积日基数"的最优选值、优良指标的分布规律、回归年对计算精度的影响性能、关键参数最大绝对偏差的分布规律及赤纬和时差函数的拟合性能5个方面的综合对比分析。选取王炳忠法(Wang法)、Bourges法、Spencer法等7种经典简化算法为实例,对模型展开应用研究。结果数据表明:Wang法、Bourges法和Duffie法的积日基数最优取值分别为1、1和-1,其他方法为0;在优良指标的分布上,Wang法和Brouges法占明显优势;在时差和赤纬计算上,除Wang法和Brouges法之外的5种方法均有闰年(或每隔4a)易出现最大绝对偏差的问题;在函数拟合性上,Wang法和Brouges法占有明显优势;综合对比结果显示:Wang法最优,Brouges法次之。According to the characteristics of simplified solar position algorithms, the contrasting model and application of the algorithms were studied. The comprehensive analyses of the model included the optimization value of the basic day number, the distribution regulations of optimization indexes, the effect on calculating precision of tropical year, the distribution regulations of the maximum absolute deviation and the fitting of time difference and declination functions. The seven general and classical algorithms, including Wang, Brouges, Spencer, Duffle and other algorithms, were selected as examples to study model application. The results showed that the optimization values of the basic day number for Wang, Bourges and Duffie methods correspond to 1,1 and - 1, and other meth- ods correspond to 0. As to distribution regulations of optimization indexes, Wang and Brouges methods are obviously dominant. In the area of time difference and declination calculation, every method is easy to show the maximum absolute deviation in a leap year （ or every four years） except Wang and Brouges methods. Comparing to other algorithms, Wang and Brouges methods have obvious advantage in the fitting of time difference and declination. The combining of separate elements show that Wang method is the best, and Brouges method takes second place.
