局部振动对骨关节的危害,文献中以机械工业使用风动工具报导为多。为了解特钢厂使用高频率,小振幅电动振动工具所致骨关节的损伤,本文对79名接振工人的手、腕、肘骨关节X线片进行了观察与分析,报导于下: 材料与方法 1.观察对象:79名中分别为风钻工9人,风钻主频段1000(Hz),振幅4.95mm,加
Local vibration hazards of bone and joint, the literature to the use of pneumatic tools for the mechanical industry as much. In order to understand the damage of the bone and joint caused by the high-frequency and small-amplitude electric vibration tools in the special steel mills, 79 X-ray films of the joints, wrist and elbow joints of surge-vibration workers were observed and analyzed. And method 1. Observation object: 79 were respectively 9 people wind drill, wind main frequency band 1000 (Hz), amplitude 4.95mm, plus
