英文摘要	The Landweber scheme is a method for algebraic image reconstructions. The convergence behavior of the Landweber scheme is of both theoretical and practical importance. Using the diagonalization of matrix, we derive a neat iterative representation formula for the Landweber schemes and consequently establish the convergence conditions of Landweber iteration. This work refines our previous convergence results on the Landweber scheme.; Mathematics, Applied; SCI(E); 中国科学引文数据库(CSCD); 0; grqu@bjtu.edu.cn; 1; 111-118; 30
