Finally, the model is built by constructing a dynamic gray target, and then the healthy state of transformer is obtained by the state classification strategy.

最后，通过构造动态灰靶评价模型求得靶心度，再结合状态分级策略得到变压器的健康状态。

Parameters describing character of gray cast graphite morphology such as fractal dimension, roughness and regression coefficients were used to the classification.

用于描述石墨形态的特征由分形维、粗细参数和二维自回归系数共同组成。
