本文研究了圆柱形固体中层状和径向连续变化的非均匀热物理性质的热波深度剖面的相似归一化方法,并与非均匀平板固体的理论和实验光热辐射测量方法相联系。非均匀圆柱形固体的整体热波场的曲率效应的反卷积允许将常规的直线热波反问题技术应用于层状和非均匀深度变化的圆柱形固体的热导率深度剖面重建,并为使用现有的平面逆技术的这种固体的深度轮廓术开辟了新的可能性。
A similarity normalization method for thermal-wave depth profiling of layered and radial continuously varying inhomogeneous thermophysical properties in cylindrical solids is investigated and related to that developed for inhomogeneous flat solids both theoretically and experimentally using photothermal radiometry. The deconvolution of the curvature effect out of the overall thermal-wave field of inhomogeneous cylindrical solids allows conventional rectilinear thermal-wave inverse-problem techniques to be applied to thermal conductivity depth profile reconstructions in layered and inhomogeneous depth-varying cylindrical solids and opens new possibilities for depth profilometry of such solids using existing flat-surface inverse techniques.
