摘　　要：本文推导计算了ITRF2005与ITRF97的框架转换参数,对框架转换和历元归算进行了深入研究。利用国内4个IGS站的数据,对先历元后框架和先框架后历元的两种转换方法进行实例验证,分析了转换结果的精度,并对坐标转换方法的使用提出了一些建议。The parameters of frame transformation from ITRF2005 to ITRF97 are deduced for calculation in this paper, and the frame transformation and epoch reduciton are researched deeply. With the data from the four IGS stations in China, the two transformation methods of frame-before-epoch and epoch-before-frame are validated by examples. Finally this paper analyses the accuracy of conversion results and gives some suggestions for the use of coordinate transformation methods.

关 键 词：ITRF框架 CGCS2000 框架转换 历元归算
