【摘要】 基于未确知数学中有关盲数理论,对不确定性信息下河流水质风险分析问题进行了初步研究。在引入包含灰性、未确知性等不确定性的水环境参量盲数的基础上,提出了水质风险分析的未确知风险概念及未确知风险测度,并建立了相应的表达形式和计算方法。实例研究表明,对水环境风险,尤其是非突发性水质风险所建模型具有很好的适用性。更多还原

【Abstract】 Based on blind number theory in unascertained mathematics, primary research on water environment risk is made with uncertained information. On the basis of introduction of water environment paramatric blind number with grey uncertainty and unascertained uncertainty, unascertained risk concept and measure are put forward, and corresponding form of expression and method for calculation are set up also. Study result shows that the model established in this paper is suitable for analysis of water environment risk, especially for nonsudden risk.更多还原
