A knowledge of the air movement around a worker in a low-speed airflow is important in a number of areas: containment testing of fume cupboards; testing of personal dust samplers; testing of LEV effectiveness; and measurement of worker expo...
Scanning electron microscope sizing of airborne fibre samples: a preliminary investigation into the effects of the variable inclination of fibres to filter surfaces [0.03%]
纤维与滤膜表面倾斜角度对电镜法测定空气中纤维样品长度的影响研究初报
