摘　　要：提出了一个简单而有效的确定黑体辐射中温度分布的方法,所提出的方法完全不同于以前的方法.基于再生核方法,温度分布的精确表达式和稳定的数值算法被给出.最后,用带有高频扰动的数值算例来验证提出的算法的有效性.A simple and efficient method for determining area temperature distribution of the inverse black body radiation problem is presented. It is different from previous works. The exact expression for the solution and stable numerical algorithm are given based on the reproducing kernel method. And the feasibility of this algorithm is demonstrated in a computational experiment with high - frequency perturbation.
