摘　　要：多项式拟合法探测周跳因其算法简单,适合计算机编程而被广泛地应用。然而,其探测精度也受到观测误差和采样频率的影响。因此,提出了多项式拟合法结合历元间差分和B-spline曲线插值法的新方法来解决这两个方面的问题。介绍了新方法的原理和模型,最后利用采集的数据进行了方法验证。The polynomial fitting method is used widely to detect cycle slip for its easily computer programming and simple algorithm. As for its accuracy,it is restricted by the observation errors and the sampling rate. A new method which combines with polynomial fitting method and the B-spline curves interpolation is presented in this paper. This paper introduces the mathematical theory and model. And finally a test is made to show the reliability of this new method.
