摘要
在柱坐标下,建立热单轴介质光热辐射的三维理论模型,比较后得知一维模型的不足。同时,得出入射高斯光束光斑半径与样品半径之比大于0.7时,三维理论模型完全可用一维理论模型替代。
The 3-Dtheoretical model of photothermal radiation of thermally uniaxial materials is built in the cylindrical coordinate axes. Compared with the 3- D theoretical model, the 1-D one is defective. At the same time, if the ratio between the radius of incident Gaussian beam and that of the sample is overt0. 7, the 3-D theoretical model is replaced completely by the 1-Done.
