| 摘 要： | 本文报道了733名接触全身振动和201名非接振工人的工效观察结果,研究提示全身振动确可导致机体的工效降低,表现为闪光融合频率的辨别能力平均插板数和短时记忆力减低,视——运动反应时延长及视读错误率增大,其中以后两项指标改变较明显,统计分析结果表明,接触全身振动作业人员的工效减低程度与振动强度和频率有关,同时还与暴露时间密切相关。

| Abstract: | Effects on work efficiency of 733 workers exposed to whole body vibra-tion were observed with 201 nonexposed workers as controls.The resultsshowed that whole body vibration do effect work efficiency.The ability to dis-tinguish flicker fussion on frequency,average of Purdue Pegboard andshort-term memory were lower in exposed group than in the controls.Visualreaction-time test and reading error rate were significantly higher in exposedsubjects.Further analysis by statistics indicated that the changes of work effi-ciency in workers exposed to whole body vibration were related to vibrationalintensity,frequency and duration. |
