摘要：

The cooling down process of building structures after heating up with an external radiation source was analysed to detect voids inside and below the surface of a concrete test specimen containing voids with different sizes at various depth or covered with carbon fibre reinforcing laminates. These experimental investigations were compared to the results of simulations performed with a finite difference program. (C) 2002 Elsevier Science B.V. All rights reserved.
