摘　　要：测试了木工圆锯机床操作者操作过程中的HRV,分析了操作者生理、心理和情绪的变化。结果表明,机床操作和机床开动导致操作者SDNN、RMSSD、LF及HF增加,LF/HF降低;这种变化与操作者熟练程度负相关。结论:操作者在操作圆锯机床时自主神经系统兴奋性增加,平衡性降低;熟练操作人员具备较好的情绪稳定性和神经的自主调节能力。By analyzing heart rate variability on workers operating circular saw machines,this article analyzed workers＇ physiological,psychological and emotional variation.Rusults：the starting and operating on circular saw machines lead to the increase of operators＇SDNN,RMSSD,LF and HF dates and the decrease of LF/HF dates.This kind of variation is negatively correlate with the extent of operators＇ skillfulness.Conclusions：when working on circular saw machinery,operators＇autonomic neural systems show increasing excitability and decreasing sense of balance;skilled operators have better emotional stability and higher adjusting capability on autonomic neural system.
