将中子共振吸收光谱(N-RAS)与计算机层析成像相结合，应用于非均匀块状物体的测温。这种新方法提供了物体平面横截面上的核素温度的二维分布，作为遥感分析的信息。实验结果与物体内部的实际温度分布吻合较好，实验模拟正确地再现了实验结果。为了更高的精度，我们需要实现更精细的空间分辨率和更好的对N-RAS的统计依赖。这一新方法的发展与利用中子进行遥感和非破坏性测温的新工业应用有关。(C)2005 Elsevier B.V.保留所有权利。
Neutron resonance absorption spectroscopy (N-RAS) associated with computer tomography was applied to thermometry for an inhomogeneous bulk object. This new method provides two-dimensional distributions of nuclide temperatures on the planar cross-section of an object as information from remote-sensing analysis. The experimental result showed good agreement with the actual temperature distribution inside the object, and the simulation of the experiment correctly reproduced the result. For greater accuracy, we need to achieve finer spatial resolution and better statistical reliance on N-RAS. The development of this novel approach has links to new industrial applications utilizing neutrons for remote sensing and non-destructive thermometry. (c) 2005 Elsevier B.V. All rights reserved.
