摘　　要：实测了人扎针孔0.6 mm和1.0 mm时高效过滤器对于大气尘的泄漏浓度,当上游大气尘浓度只有300～400粒/L时,下游仍可测出5～10粒/L的泄漏。Uses atmospheric dust as upstream aerosol challenge and pricks a pinhole of diameter 0.6 mm or 1.0 mm on a HEPA filter. The results show that leakage can still be detected with 5-10 particles per liter sampled downstream when the upstream concentration is as low as 300-400 particles per liter.
