摘　　要：确定面源恶臭挥发率的方法一般有两种:间接采样法和直接采样法。直接采样法由于具有许多优点而得到了广泛的应用。采样设备的选择会影响到恶臭样品的组成,通过对比可知,由动态采样器和静态采样器确定的恶臭挥发率的结果是不同的。用风洞法确定的恶臭挥发率与用间接法确定的恶臭挥发率有较好的一致性,可以作为恶臭扩散模型的输入参数。Two general approaches are usually identified to estimate emission rate values for area sources： indirect measurement and direct measurement. Direct measurement has a number advantages and been used widely. The selection of an odour sampling device may influence the composition of the resulting edour sample. Limited comparison of emission rates derived from turbulent and essentially quiescent sampling devices confirms that the emission rates derived from these devices are quite different. In general, the ability to relate emission rate estimates obtained from wind tunnel measurements to those derived from device-independent techniques supports the use of wind tunnels to determine emission rates that can be used as input data for dispersion models.
