二维有限平板边界上热分布的Sinc近似
Sinc Approximation of the Heat Distribution on the Boundary of a Two-Dimensional Finite Slab
摘要：
我们考虑的二维问题，恢复全球的时间在表面上的热分布的一层内的热传导体从两个内部温度测量。这个问题是不适定的。近似函数用二维Sinc级数表示，并给出了误差估计。
英文摘要：
We consider the two-dimensional problem of recovering globally in time the heat distribution on the surface of a layer inside of a heat conducting body from two interior temperature measurements. The problem is ill-posed. The approximation function is represented by a two-dimensional Sinc series and the error estimate is given.
