Title:
METHOD OF SEARCHING FOR UNSTEADY DUST SOURCE POSITION OF DUSTFALL
Document Type and Number:
WIPO Patent Application WO/2013/024875
Kind Code:
A1
Abstract:
The product is taken of a coefficient (B1) and central axis vertical sectional areas (Sp1, Sp2) of dust source search regions relating to evaluation points (iM, iN) at a coordinate point (p) in first and second generation source search regions (γ(iM, it), γ(iN, it)) having a central axis extending to the windward side of a representative wind direction (WD), with the evaluation points (iM, iN) as start points; and assumed dust amounts (E1, E2) are calculated. It is then determined whether the ratio of the assumed dust amounts (E1, E2) falls within a predetermined range.
