METHOD OF SEARCHING FOR UNSTEADY DUST SOURCE POSITION OF DUSTFALL

摘要

rating point (i _M , i _N and ) as a point, having a center axis extending in the direction of the representative wind direction WD first and second source search range (i _M , i _t ), (i _N , i _t ) in the coordinate point (P) according to the evaluation points ( _M , i _N ) central axis vertical cross-section of oscillation sources navigation area on the S _p1 , S _p2 coefficient B ₁ home rash amount by multiplying E ₁ , E _{2 calculates the} , assuming rash amount of E ₁ , E ₂ of it is determined whether the ratio is within a predetermined range.
