关于Simpeds早期的研究 Simpeds是由英国采矿安全研究中心(SMRE)专门为测定个体粉尘量而设计的。1967年希金斯和杜尔报告了英国铸铁研究协会研制的旋风采样器,而汉密尔顿等指出它具有与113A型大致相同的呼吸性粉尘的粒度选择性能(1967)。Simpeds的采样头是这种旋风采样器中较轻型的一种,修改后可以戴在工人的头灯上。哈里斯和马圭尔于1968年找出了花粉尘巷道中Simpeds与113A型的关系,但收集的粉尘约10％以上。其后的改进使Simpeds更适合大量生产(马圭尔等,
About Simpeds Early Research Simpeds was designed by the British Mining Safety Research Center (SMRE) specifically to measure the amount of individual dust. In 1967 Higgins and Durr reported the cyclone sampler developed by the British Society for Cast Iron Research, while Hamilton et al. Pointed out that it has a particle size selectivity (1967) of approximately the same respirable dust as Type 113A. The Simpeds sampling head is the lighter type of this cyclone sampler and can be worn on the worker’s headlamp after modification. Harris and Maguire in 1968 identified the relationship between Simpeds and type 113A in pollinated alleyways, but collected about 10% more dust. Subsequent improvements made Simpeds more suitable for mass production (Maguire et al.
