【摘要】 利用边界元素法（ＢＥＭ）对二维方形域和多连通的环形区域热传导反问题进行了求解。考察了内点位置，温度误差对求解结果的影响。结果表明内点温度的测取精度对结果的影响是呈线性的，并且内点距所求温度边界距离愈近其解的精度愈高。更多还原

【Abstract】 A method of solution using the boundary element method (BEM) is developed for two dimensional inverse problem of heat conduction. For a square and a ring regions,the effects of the temperature error and the inside point locations on the results is also discussed. The results shown that the calculated error is a linear change with the precision of inside point temperature and that the nearer the inside point location is to the boundary solved,the higher the calculated precision is.更多还原
