【摘要】 测定了同一水样在不同水温下、不同水样在相同水温下及不同水样在不同水温下的“水呼吸”耗氧速率．并在此基础上采用回归分析，研究了主养链鱼和鳙鱼的池塘的“水呼吸”耗氧速率与水温、化学耗氧量和透明度三者的相关性．结果表明：“水呼吸”耗氧速率与水温呈指数关系，与化学耗氧量呈直线关系，与透明度的关系受水色的影响．同时建立了多元非线性回归方程更多还原

【Abstract】 Oxygen consumption rate of water respiration is measured at different temperatures in the same water or at the same temperature in different sample water or at different temperature in different water.On this base,the correlation is studied among the oxygen consumption rate of water respiration,temperature,chemical oxygen demand and transparency in ponds where silver carps and variegated carps are raised.As a result,the relation among them is linear,the transparency is affected by water color and the equation of regression is determined.更多还原
