摘　　要：以Polangi—Wagner模型为基础、谱峰高的方差为目标函数,用单纯形加速法对TPD谱图进行定量解析,求算脱附活化能和指前因子,计算值与理论值一致,对重叠峰的解析结果更为理想.According to Polangi-Wagner model, the TPD spectra were resolved quantitatively by simplex optimization method. The variance of spectrum peak height was adopted as an objective function in the method. The theoretical activation energy and pre-exponential factor were identical with the calculated ones. Good results have also been obtained for the overlapping double peaks.
