摘　　要：对我厂正火处理后的20#吊杆进行了3年的力学性能数据统计,采用回归方法求出了回归方程σb=181+2.24HB(MPa),可以通过HB值算σb,也可以从σb来估算HB,从而减少抽检数量。检查部门通过本文论述,结合生产情况可减少HB的检查数量。The data statistics of mechanical property of three years for 20# boom after normalization treatment of our factory are done and get regression equation σb=181+2.24HB(MPa) employ regression method. σb value may be counted through HB and HB value may also be counted through σb hence decrease amount of take sample. The inspection amount of HB may be decreased by inspection department through the discuss combining production thing.
