由于作业机械化程度的提高使全身振动和局部振动的职业接触增加。众所周知接触振动可致循环障碍,即振动性向指。但使用振动工具的工人不仅影响循环系统,还可导致神经系统及骨关节障碍。长期接触全身振动引起背部及胃部损害是有疑义的。然而,在全身振动状态时,振动作用与这些潜 Occupational exposure to systemic vibrations and local vibrations increases due to the increased mechanization of work. It is well known that contact vibration can cause circulatory disturbance, that is, vibration to the finger. However, workers using vibration tools not only affect the circulatory system, but also lead to nervous system and joint disorders. Long-term exposure to systemic vibration caused by back and stomach damage is questionable. However, the vibrations act with these submersibles in the state of whole body vibration
