摘　　要：讨论了常见的几种概率密度函数,引入p-范分布,以GPS RTK为实验数据,利用皮尔逊χ^2检验法进行假设检验。在分布呈单峰的前提条件下,选择合适的p值可得到更接近的真实误差分布,为更加合理准确地处理GPS观测数据提供了理论依据。This paper discusses some common probability density functions with Pearson χ^2 test and GPS RTK（realtime kinematic）experimental data.On the basis of a single peak in the distribution,this paper conducts statistical tests for GPS RTK observations,and gets a suitable Pvalue to get more exact error distribution,which offers theoretical reference to process GPS RTK observations more reasonably and accurately.
