In chapter 5, heat mechanism and heat radiating forms of the hydraulic system faults are studied. Based on relationship between degree of the hydraulic system faults and thermal image shapes, multi-scale entropy of temperature field is taken to express the fault degree. Entropy of low frequency means its absolute temperature, and entropy of high-frequency means distribution of temperature field.

同时针对系统故障程度的不同，提出了用温度场的熵进行表征的思路，通过多尺度小波对原热场图像进行小波变换，提取其中低频分量的熵用来衡量其绝对温度大小，提取高频分量的熵来衡量其温度场的分布，给出了实验结果，通过实验结果分析，证明这种分析方法是可行的。
