回归法应用于PVC管材室内自然老化性能的预测
Forecast of Regression Method Applying in Indoor Natural Aging of PVC Pipe
【摘要】 对建筑用聚氯乙烯(PVC)塑料管材进行室内自然老化测试,得到几组老化后拉伸强度数据,利用非线性回归法,得到室内自然老化的预测数学模型。经与试验数据比较,该预测模型的误差范围在-3.2%~0.9%。
【Abstract】 The natural aging of PVC plastic pipe use for building was tested,and several groups of aging tensile strength data were obtained.The natural aging forecasting mathematical model was get by using nonlinear regression method.After compared with test data,the error limit of forecasting model was from-3.2% to 0.9%.
