【摘要】 [目的]比较研究3国不同粉尘采样器的测定结果。[方法]采用中国、美国和德国总尘和呼尘采样器在武昌造船厂的清铲和造型车间于呼吸带高度进行平行采样8d,并测定总尘、呼尘浓度。[结果]中国、美国、德国的总尘和呼尘采样器的测定结果具有一定的相关性(P<0.05)。但中国总尘采样器的测定结果与美国、德国的结果有差异(P<0.05);而呼尘间无差异(P>0.05)。[结论]我国呼尘采样测定结果与国外采样器测定结果具有可比性。更多还原

【Abstract】 [ Objective] Comparative studies on the dust concentration with different sampling methods. [ Methods] We determined the dust contention in the Wuchang shipyard for 8 days with different sampling instruments,i.e. total dust and respirable dust samplers from China,Germany and USA. All the samplers were located in the workplace at a height of respiratory zone,to make a parallel sampling. [ Results] Using the samplers from China/Germany/USA,there was correlation between the result of total dust and that of respirable dust. There was significiant difference in the results of total dust between the Chinese instruments and German or USA instruments(P < 0.05),but no significant difference among the results of respirable dust sampled by threes kinds of samplers(P > 0.05). [ Conclution] The results of respirable dust suggested that Chinese instrument was comparable with Germany and USA instruments.更多还原
