依据污染源蒸发量和介质密度,建立了汽油清洗间通风量和定员限量计算公式,测定了汽油蒸发速度,按计算方法归纳为五个步骤,并首次在安全性评价中应用,效果满意。 Based on the sources of evaporation and medium density, the formula for calculating the ventilation rate and the capacity limit of gasoline washing room was set up. The evaporation rate of gasoline was determined. The calculation method was summed up into five steps and applied for safety evaluation for the first time, with satisfactory results.
