Abstract: This paper describes an imperfect pulse injection stimulus-response technique to study the axial mixing in the extraction column. The comparison among various methods of parameter estimation shows that the least-squares fitting method in the time domain is more accurate one. The uncertainty are discussed. Effects of pulse amplitude and frequency were studied in the standard sieve plate pulsed column.

摘要： 本文以非理想脉冲注入的扰动-响应技术,进行萃取柱轴向混合的研究。各种参数估值方法的比较表明,时间域最小二乘拟合法较为精确。本文还讨论了参数估值的不定性问题和计算时间问题。在标准结构的脉冲筛板柱内研究了脉冲振幅和频率对轴向混合系数的影响。
