摘要：Two electrical wires are connected to the surface of an electrically conductivesolid body at two measurement points located on either side of a crack in the surface ofthe body. The two wires form a thermoelectric couple. A constant DC current is appliedto the body. The two wires are connected to a device for measuring the extent of thecrack and another device for measuring the temperature of the crack. By measuring thepotential difference during application and interruption of the DC electric current to thebody, it is possible to simultaneously obtain a measurement of the extent of the crackand a measurement of the temperature of the crack.
