| 摘 要： | 讨论水准标尺误差在垂直形变资料中的影响。标尺误差以系统误差为主，对形变资料的影响在小范围内近似为尺度比例误差，在大的时空范围内具有系统性与偶然性相间影响的双重特性。它必然产生程度不同的地形相关现象，使用资料时要充分顾及尺长误差的历史状况。为满足形变监测的需要，应从标尺的制造工艺、检定精度、使用过程及资料预处理方面加以改进，进一步提高尺长的精确度。

| Abstract: | The influence of leveling staff error on the data of vertical crust deformation is discussed.The errors are mainly systematic error.The influence is a similar to scale error in a small area. and has two kinds of character of being systematic and random in a big range of time and space,that make the data relative to the terrain in survey region.The former circumstances of the staff errors of data must be noticed when the data are used.In order to improve the precision of staff length,the manufacturing technology and testing precision of the staff need to improve and the method of preprocessing needs too. |
