摘　　要：在简要介绍了由Hofmann等提出的迭代最小二乘法天文像复原法 :砌砖法 (Buildingblock)的原理后 ,提出用斑点干涉术等方法对被观测目标像的范围大小进行大概估计的预处理方案 ,这样将做到对砖块的区域限定投放 ,避免大量无效的砖块投放迭代步骤。天文高分辨率像复原实验表明 。The principle of the method of Iterative Least-square(Building Block) proposed by Hofmann et al.is introduced briefly.A pretreating programme for estimation of the area size of the image of an observed object by the speckle interferometry or another way is posed.Putting blocks in the limited area is achieved and a great quantity of blind iterative steps of putting blocks will be avoided.The experiments of astronomical high resolution image reconstruction showed that the efficiency of the Building Block is raised obviously.
