An opitical fibre-infrared measuring instru- ment has been developed,the mechanism of grinding sparks and its statistical properties,mathematical model as well as spectral analysis of the sparks temperature system are discussed.

• 本文提出了通过磨削火花温度在线辨识磨削烧伤,研制了光纤一红外测温仪,对磨削火花温度形成机理,统计特性,数学模型、频谱特性进行了系统的研究。
