数据误差分为随机误差（Randomerrors）和过失误差（Gross errors）两类，前者受随机因素的影响（如操作过程的微小波动或检测信号的噪声等）； 后者包括仪表的偏差和故障（如堵塞、校正不准或基准漂...

In survey,gross errors may occur in the observing date,which brings difficulties to the data-processing. Therefore,the gross errors must be detected and omitted timely.
测量工作中,观测数据可能会带有粗差,从而给数据处理带来困难,因此必须及时的发现并剔除观测数据中的粗差。
