When the front surface of the specimen is radiated by a laser pulse, the thermal diffusivity a can be obtained by the temperature rising history of the rear surface of specimen ( i.e. Parker's method). 当样品的前表面被一束脉冲激光照射时,可从样品后表面的温升历程得到热扩散率,此即Parker的方法。
Parker's inversion method was applied to density interface inversion of high-precise gravimetric data in the Jiyuan basin. 本文采用parker反演方法对济源盆地的高精度重力观测资料进行了密度界面反演。
