在近代工业生产中,由于风动、电动工具如风铲、凿岩机、捣固机、电钻、砂轮机等的广泛应用,使掌握这些工具的操作工人受到了程度不同的振动,因而就有可能罹患振动病。 国内外对局部振动病的一些调查研究表明,对工人健康有影响的,主要是振动频率、振幅和反冲力。长期接触振动,其局部症状一般表现为手胀、麻木并有发热感,随之可发生手痛、手发凉、手颤及手指关节变 In modern industrial production, due to the wide range of applications of wind power and electric tools such as wind shovels, rock drills, tamping machines, electric drills, grinders and the like, operating workers in possession of these tools are subjected to varying degrees of vibration and thus may suffer from Vibrating disease. Some domestic and foreign research on local vibration disease research shows that the impact on workers’ health are mainly vibration frequency, amplitude and recoil force. Long-term exposure to vibration, the general symptoms of its performance for hand-bloating, numbness and fever, followed by hand pain, hand cold, hand tremor and finger joint changes
