摘要
本文用逐步选择因素组合法，对锥形件拉深临界压边力试验数据进行了处理，所得数学模型比一般逐步回归法具有更高的精度和可靠性，模型更为完善。
The experimental data of the critical blank-holder pressure on the tapered drawn components have been treated by the method of progressive selection of combined factors,It gives out a more perfect regression model with higher precision and reliability.
