摘　　要：在随着2000国家大地坐标系在全国不断推广与应用,将ITRF2000框架下的坐标转换到CGCS2000框架时,需先转换到ITRF1997框架下。采用布尔沙——沃尔夫模型对基于不同基准的两框架之间进行坐标转换,设计七参数求解程序,并通过实例分析验证其准确性和可靠性。With the increasingly promotion and application of China Geodetic Coordinate System 2000 in China,the coordinate under the ITRF2000 is needed to be switched under the ITRF1997 before the CGCS2000.Burse-Wolf Conversion Model is applied to transform the two coordinate systems under different standards.A seven-parameter solver code is designed and its accuracy and reliability are verified by examples.
