摘要基于空气动力学原理,提出了一种针对浮游菌采样器采集物理效率的新型检测方法,并搭建了检测装置,可以得到连续的采样效率曲线,直观获取不同动力学粒径对应的采集物理效率。分别评价了2款国产及1款进口的浮游菌采样器采集物理效率,结果发现国产采样器采样效率不及进口品牌,质量还有待提升。研究了多分散的亚利桑那超细试验粉尘与单分散颗粒物标物检测结果的差异,发现国产采样器的差异大于进口采样器。所提检测方法有助于提高浮游菌采样器采集物理效率检测的准确性、科学性及检测效率。

Abstract：Based on the principle of aerodynamics, a new detection method for the physical efficiency of plankton sampler was proposed, and a detection device was built to obtain continuous sampling physical efficiency curves and intuitively obtain the collection efficiency corresponding to different dynamic particle sizes. The sampling physical efficiency of two domestic and one imported sampler was evaluated. The results showed that the sampling efficiency of domestic sampler was not as good as that of imported sampler, and the quality of domestic sampler needed to be improved. The difference between the detection results of multi-dispersed Arizona ultrafine test dust and monodispersed particle standard was studied. It was found that the difference of domestic sampler was greater than that of imported sampler. The proposed study is helpful to improve the accuracy, scientificity and detection efficiency of the sampling physical efficiency of plankton sampler.

Key words： metrology plankton sampler sampling physical efficiency detection efficiency aerodynamics
