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。
Hydrology theoretically deduces the relationship between the transient signal and the temperature coefficient of pulse thermal beam deflection. It is proved that the thermal coefficient of thermal properties can be determined by the transient flood number of pulse light thermal beam deflection. This method is characterized by non-contact transient measurement.
