粉尘粒子在巷道空间中自净特性的研究

Study on the Self purifying Characteristic of Dust Particles in the Roadway

为研究粉尘粒子在巷道中的自身净化机理，分析了粉尘粒子的紊流弥散机理及自由沉降机理，导出了稳态时粉尘粒子的自净效率计算公式。

To study on the mechanism of the self purifying characteristic of dust particles in the roadway,the mechanisms of turbulent dispersion and free settling of dust particles are analysed and a calculation formula for the self purifying efficiency of dust particles in steady state is derived.
