Dulkių koncentracijų palyginamieji tyrimai

Accuracy of hard particles concentration measurement is affected by different influence quantities. Main of them are discussed, analyzed and introduced in the theses. The aim of the investigation was to measure particles concentration with different instruments in real conditions, to compare and ana...
