摘　　要：出于对目前常用的两种坐标系转换模型的学习和理解,对原本适合于小角度坐标转换的布尔莎模型进行了拓展,使其适合于任意角度坐标转换。将改进后的7参数布尔莎模型与13参数的大角度模型,结合盾构三棱镜法解算盾首盾尾坐标的工程实例,通过大旋转角和小旋转角两组数据以及编程实现两者的对比,并得出了结论。For the purpose of the research on the two current main methods of coordinate transformation,I expanded the Burse transformation model which was only fit for narrow angle to fit any angle transformation.Improved Burse transformation model of 7 parameters and 13 parameters transformation model are studied.Associating an example of the shield calculating the coordinate by the mean of three prism calculation,We did the comparison and drew a conclusion through the two sets of data including wide-angle data and narrow-angle data and programming.
