hit theory

A grey target theory based method for state assessment of power transformer;

基于灰靶理论的电力变压器状态评估新方法

The grey target theory is used to set up the model for mathematical evaluation;the tactical and technical performance indices,which reflect the effectiveness of weapon systems best,is used to form the index series of weapon systems to be evaluated(namely,the modes),and the standard mode of these index series is derived according to the .

即:首先用灰靶理论建立评定方法的数学模型,以能反映武器系统效能的战技性能指标构造各比较方案或模式的指标序列,进而求得各指标序列的标准模式。

And then grey target theory was introduced and the bull s-eye was decided.

然后引入灰靶理论,在得到的序列中构造标准模式,通过靶心度计算进行设备磨损模式的分级,最后得到设备在给定模式的运行状态判定结果和设备中存在的按照从重到轻的磨损模式顺序,和专家分析结果完全一致。
