车间环境粉尘浓度的监測,国內主要的方法是:在粉尘环境中工人经常逗留地点或其它地方,进行多次有代表性的短时采样测定表示。它虽有优点,但测定结果的平均值,不能反映工人一个工作班的时间平均接触粉尘浓度的情况。因此研究监测粉尘环境中,工人一个工作班的时间接触粉尘的平 The main domestic method for monitoring the dust concentration in the workshop environment is to conduct several representative short-time sampling measurements in the dusty environment where workers often stay or other places. Although it has the advantage, the average value of the measurement results does not reflect the time average exposure to dust concentration of a worker in a working class. Therefore, research monitoring dust environment, the working hours of a worker in contact with the dust level
