【摘要】：為了提高煤礦粉塵分布測量效率,縮短在線測量時間,以光散射理論為基礎(chǔ),利用程函近似方法對散射波較好的近似性能,將光全散射法中Mie理論計(jì)算顆粒消光系數(shù)復(fù)雜等問題采用改進(jìn)的程函近似方程進(jìn)行優(yōu)化。對常用的單峰R-R窄帶、寬帶顆粒粒徑分布進(jìn)行實(shí)驗(yàn)?zāi)M,結(jié)果表明,重建模型基本符合預(yù)定分布,對設(shè)定模擬參數(shù)加入5%隨機(jī)噪聲時,粒徑重建分布得到滿意結(jié)果,消光系數(shù)矩陣計(jì)算速度提高48倍以上。
[Abstract]:In order to improve the efficiency of coal mine dust distribution measurement and shorten the on-line measurement time, based on the light scattering theory, the equation function approximation method is used to approximate the scattering wave. The complex calculation of particle extinction coefficient by Mie theory in the full scattering method is optimized by the improved equation function approximation equation. The common single peak R 鈮，
