摘要: 本文提出两个修正的PST迭代格式,并给出了数值试验的对比结果。试验结果表明,该格式能在一定程度上降低对初值的要求,也能减少一定的计算量。

Abstract: The modified PST iterative sclremes of solving the inverse problem are proposed in this papar.It is found that the modified PST dose give satisfactory results,and its computational work is less than the PST[2] iterative Schemes. Finally, the results of the numerical experiments are given.
