脉冲光热光束偏转测定导温系数
Pulsed Photothermal Probe Beam Deflection Measurement of Thermal Diffusivity
【摘要】 水文在理论上推导了脉冲光热光束偏转瞬态讯号与导温系数关系,证明可由脉冲光热光束偏转瞬态汛号测定热物性的导温系数。本方法的特点是非接触瞬态测定。
【Abstract】 In this paper we obtain theoretically the relationship between the transient signalof pulsed photothermal deflection and the thermal diffusivity.It shows that the thermal diffu-sivity can be measured experimently by the deflection transient signal.This method is a real timenoncontact measurement.
