摘　　要：根据反问题理论和离散反演算法建立了 BOD5- DO参数反问题偶合模型 ,并推导出偶合模型的参数解式。对复氧系数、耗氧系数、沉淀 -再悬浮系数、光合作用产氧 -生物呼吸耗氧系数和自净系数随空间变化规律进行了定量计算 ,为河流水体自净规律的研究开辟了新途径。WT5BZ]:A BOD 5 DO parameter inverse coincidence model is set up in this paper according to the verse theory and the dispersed inverse arithmetic method.The Parameter formulas of the coincidence model are educed. The deoxygenation rate, reaeration rate, deposition and suspend once more coefficient, photosynthesis reaeration and abc warfare breath deoxygenation coefficient, and self clearing coefficient by space are quantitaively calculated also,giving a new approach for water self clearing rule reserch.
