Calculating Particle Size Distribution Rapidly by Multi-Stage Impactor

Objective  To eatablish a data processing station to solve the time-comsuming manulal calcution when measuring partioutate matters by multi-stage inpater(WY-1).

Method  Based on the requirement of WY-1 data processing, a GBSS "data processing station" was developed l)y the GPSSS quick calculating software and apply Microsoft Visual Studio 2013 C#; the set of dynamic link library and procedure executive program were all based on the requirement of Microsoft Framework 3.5.

Results  After inputting the data from WY-1, the following results could be obtained:the cumulative mass percent of particles less than different cut-off diameters/(D_c); the cumulative mass percent of particles less than different diameter D (including PM₁₀ and PM_2.5) based on the regression line of log-normal probability distribution, medium diameter D₅₀ and geometric deviation S_g.

Conclution  Only several minutes was needed to complete the whole calculation on GBSS "data processing station".The time for data processing was greatly shorten, which may render the WY-1 test creating an evident environmental benefit in multiple domains.
