英文摘要：

This paper discussed the uncertainty analysis method of some SPIV results measured inside the compressor rotor.The convergence characteristics of the SPIV results of the three velocity components,the first-order results（vorticity） and the second-order statistics（the Reynolds stress） were investigated,and the measurement accuracy was analyzed.Then,the analysis of the main influential factors to the measurement accuracy of high-order statistics was carried out.At last,some advices for improving the measurement accuracy of SPIV in turbomachinery were given.
