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.

Abstract: According to Polangi-Wagner model, the TPDspectra 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.
