摘要
文中采用牛顿(切线)法和计算机技术求极值,对中小河流可降解有机物衰减指数进行了计算。该方法应用于小清河的有机污染物衰减指数k值的计算。结果表明:该方法可提高水环境容量计算的可靠性和准确度。
Using the Newton Method to get the extremum and computer technology, the paper calculated the attenuated exponent of degraded organic matter. The method was applied to calculate the attenuated exponent k of organic contamination in Xiaoqing River. The resuhs shows the method can improve the reliability and accuracy of calculation for water environmental capacity.
