摘要
为确定浮球直径大小和质量对水面抑制蒸发率的影响及确定最优值,采用控制变量法和对比法设计两组试验,利用SPSS等数据软件对试验结果进行数据分析,并建立不同试验设计与气象因素之间的联系模型。结果表明:在浮球没入水深为0到半径大小之间,浮球质量越大,抑制蒸发效果越好;浮球直径大小在55~100 mm,抑制蒸发率值越大;浮球在水面移动会破坏水面蒸发平衡,改变水面微气候,从而降低浮球的抑制蒸发效果。
In order to determine the influence of diameter and mass for floating ball on inhibiting evaporation rate of water surface and determine the optimal value,two groups of tests were designed by using the control variable method and the comparison method.Analyzed the test results by SPSS and other data software,and built the relationship model between the different test designs and meteorological factors.The results show that the heavier of the floating ball,the better of inhibiting the evaporation effect,when the submerged depth of floating ball is between 0 and its radius;and the inhibition evaporation rate is higher,when the diameter is 55~100 mm.The moving of floating ball on water surface can destroy the balance of evaporation and change the micro-climate of the water surface,and then reduce the effect of floating ball on inhibiting the evaporation.
