摘要
在水准测量工作中,由于仪器构造不完善、操作的精度以及工作环境的问题会产生一系列的误差,这些误差可以从技术角度减弱或者消除,介绍了水准测量中误差产生的原因以及简单的控制误差方法。
In the leveling measurement work irregularity as a result of imperfect instruments,precision operation and working conditions will have a series of errors,these errors can be reduced from a technical point,or eliminate,it describes the irregularlty of measurement of the causes and methods of control irregularity
