浓度系数技术是一种计算建筑物附近大气中空气物质从建筑物或建筑物附近释放时的浓度场的方法。浓度系数K中的操作参数，在大多数应用中，该参数与物质释放速率、风速和建筑物大小无关，但取决于风向、建筑物形状、源配置和受体位置。实际浓度的预测取决于一个人对K进行适当估计并将其转化为浓度估计的能力。本文描述了K的可用数据源，检查了它的性质，并通过一个案例研究说明了它的使用。 单位:双引文:研讨会，ASHRAE交易，1985年，第91卷，pt。你好，檀香山2B

The concentration coefficient technique is a method for calculating the concentration field in the atmosphere in the vicinity of a building when an airborne substance is released from or near the building. The operative parameter in the concentration coefficient K which, in the majority of applications, is independent of substance release rate, wind speed, and building size, but is dependent on wind direction, building shape, source configuration, and receptor location. The prediction of real concentrations depends on one's ability to make an appropriate estimate of K and to transform it into a concentration estimate. This paper describes available data sources for K, examines its nature, and illustrates its use by a case study.Units: Dual
