英文摘要：

First we optimized the ATEM 1-D forward algorithm with new Hankel filters, then theoretically higher precision can be acquired. We developed a new ATEM 1-D inverse algorithm -- alternate model adjustment method. The principle was discussed and the algorithm was described. The program was worked out, and applied for several typical models＇ forward responses, the good results prove its advantages. Compared with Zohdy＇s method, this method can achieve higher precision.
