提出一种利用先验方差信息进行测量数据处理中粗差估计的新方法——先验方差待定参数法。该方法无需进行最小二乘和假设检验，计算简便。从基本原理出发，给出其数学模型，然后通过3个算例，与QUAD法等其他常用的粗差估计方法进行对比，证明该方法的可靠性和实用性。"/>
A New Method to Estimate Gross Errors——Prior-Variance Undecided Parameter Method" />
In this paper, we introduce a new method, prior-variance undecided parameter method (PVUP), to estimate gross errors using prior variance without Least-Square or hypothesis testing. Starting with fundamental principles, we give the model of this method next. Last, we demonstrate its simplicity and validity using some examples compared with other methods, such as QUAD."/>
