摘要
考虑污染物在河流中的沿程变化规律和动态特性，建立了随空间变化的水质反问题模型，根据离散反演理论和ＰＳＴ方法，分别在时域、频域推导出两个分布参数的反演公式．
Taking account of the pollutants which are varying along the river and of dynamic characteristics of pollutants,an inverse problem model of pollutants varying in space is presented.Based on the discrete inverse theory and pulse spectrum technique,the two inverse formulas of distributed parameters E(x) and K(x) are derived in both time and frequency domains.
