摘要
通过大量的现场实测数据的统计分析,用数学回归法建立了钢管空拔时增壁量的数学模型。通过现场检验,准确性达93％。
By statistical analysis of numerous data obtained on the spot, a series of equations of increment of the steel tube wall when the tube is hollowly drawn is calculated in mathematical regression method. The accuracy reaches 93 percent when it is applied to practice on the spot.
