| 中文摘要: |
| 采用Airpak软件模拟研究在通风速率、源项强度和源项面积多因素作用下的室内甲醛扩散规律。结果表明，在室内甲醛初始为零时，源项散发甲醛后，在2 000 s内室内甲醛浓度升高较快，之后处于平衡状态。在通风速率加倍时甲醛最高浓度降低56%，源项强度减半时甲醛最高浓度降低16%，源项散发面积减少37%时甲醛最高浓度降低24%。说明通风速率对室内甲醛浓度的影响最大，其次依次为源项散发面积和源项强度。 |

| The influences of ventilation velocity， source intensity and emission area on indoor formaldehyde diffusion law were researched by Airpak software simulation. Results showed that in 2 000 seconds， formaldehyde concentration increased quickly from initial concentration of 0 mg/m3， then reached to balance. When the ventilation velocity doubled， the maximum concentration of formaldehyde decreased by 56%， as the source intensity decreased by half， the maximum concentration decreased by 16%， while the source emission area decreased by 37%， the maximum concentration reduced by 24%. It concluded that the ventilation velocity had the greatest impact on formaldehyde concentration， the next was emission areas， and the source intensity had the least influence. |
