摘要
以坐便器排水作为研究对象,通过改变坐便器的排水高度,结合不同层间排水时间间隔,探究排水高度对系统最大压力的影响。通过线性回归分析与方差分析,发现系统最大负压值与坐便器排水高度间存在显著的线性关系,不同排水高度与系统最大正压值没有显著的线性关系,但存在非常显著的影响。
The effect of drainage height to the maximum pressure of drainage pipe system was discovered by altering the drainage height of toilets with different time intervals between floors.The result of linear regression analysis showed that there was significant linear relationship between drainage height and maximum negative pressure of the system;while there was no significant linear relationship between drainage height and maximum positive pressure.However,drainage height had very significant impact on the maximum positive pressure according to the ANOVA analysis.
