摘要
在美国联邦标准FS209E中对尘埃粒子计数器采样管的长度和采集的气溶胶在采样管中的流动时间提出了要求.据此通过给出的简便图表的计算,提出了不同流量粒子计数器、不同的粒径分档的允许管长,并推荐给我国标准GB5073-98.
The transit tube length and its transit time in a particle counter is set as a demand in the American Fedend Standard 209E. The pendssible lengthes of transit tubes for different particle size ranges and different flowrates of counters are obtained from a set of simple calculating charts developed in this paper, which are recommended to China Standard GB5079 - 98.
