By this method the untouched, unsteady, instantaneousconcentration field has been measured.
并利用该方法对烟雾扩散的非定常瞬态积分浓度场进行了实际测量。

Thus, the monitoring values obtatined can only represent the instantaneousconcentration of pollutant.
监测值是瞬时浓度值,测次愈少代表性愈差。

Based on the model test, the instantaneousconcentration and velocity images in different temperatures and scales are put forwarded. And the range, shape and trend of diffusion are acquired.
