On the basic of Grey plane and area, the paper produces using the Grey area, which thepredicted value maybe close to, control the abnormal value during the computer controllingthe dynamic measurement.

• 本文根据灰平面是系统表征量发展的可能平面，灰色包络模型在向前外推预测时，灰色区间是合格预测值的分布区间定义，提出在计算机控制动态测量过程中，按预测值未来可能发展的灰色区间控制动态测量异常值。
