关于连续调制PTR三维理论模型的一点修正

A CORRECTION ABOUT THREE-DIMENSIONAL MODEL OF CONTINUOUSLY MODULATED PTR

计算侧面热交换对样品后表面相位信号的影响，证明在连续调制ＰＴＲ三维理论模型中，样品侧面绝热的假设条件在低调制频率下产生误差，必须进行修正．

Influence of the heat exchange on the side of the sample was calculated.It must be corrected in three-dimensional model of continuously modulated PTR that hypothetical heat-insulation on the side of the sample induced deviation at low frequency.
