本文主要涉及微波辐射数据的反演，用于测定人体温度分布。分析仅限于一个简单的一维分层模型，并特别关注皮肤-脂肪-肌肉结构（SFM）和肌肉-骨-肌肉结构（MBM）。在这两种情况下，都将奇异系统分析技术应用于相应的积分方程，以量化数据的信息量。数值计算表明，MBM中的信息含量比SFM中的要大得多，这可以从定性的物理考虑中猜测出来。为了评价该数学技术的有效性和实用性，文中还给出了一些数值反演的结果。
This paper refers mainly to the inversion of microwave radiometric data for the determination of temperature distributions in the human body. The analysis is restricted to a simple one-dimensional stratified model and special attention is devoted to a skin-fat-muscle structure (SFM) and to a muscle-bone-muscle structure (MBM). In both cases the technique of singular system analysis is applied to the corresponding integral equation in order to quantify the information content of the data. Numerical computations indicate that the information content is much greater in the MBM than in the SFM case, as one can guess from qualitative physical considerations. The results of some numerical inversions are also presented in order to assess the effectiveness and the practicability of the mathematical technique.
