摘　　要：系统误差是指由于某种客观原意造成的可再现误差,其数值符号保持不变或按某种规定的规律变化。在相同的观测条件下,误差在大小、符号上表现出系统性,或者在观测过程中按一定的规律变化,或者为某一常数,传统测量中系统误差可以在平差前后得到很好的补偿。随着现在测量仪器和测绘技术的发展,许多系统误差难以从观测手段中予以剔除,为尽量消除或减弱系统误差的影响以达到高精度测量的目的。本文介绍了系统误差的三种处理方法,主要包括:附加系统参数法、半参数回归法及基于系统误差延续性的附加系统参数法[1][7]。Systematic error is due to some objective meaning caused by the reconstruction error. The numerical symbol re- main unchanged or according to the rule change certain provision. With the development of surveying instruments and tech- nology now, It is hard to reject many system error [rom observation means , To try to eliminate or weaken the system er- ror in order to achieve high precision measurement purpose, Additional system parameters method, The semi parametric based on system error continuity the author introduces three adjustment methods, including： regression method and additional system parameters method
