摘　　要：在进行有毒有害气体泄漏浓度预测时,首先根据Richardson数判定泄漏是否形成重气云团,然后用重气扩散模式进行浓度预测,当泄漏气体失去重气效应后用非重气扩散模型进行浓度预测。In this paper,the concentration of toxic gas leakage is forecast,according to Richardson number,first it is determined whether the leakage forms heavy gas clouds,and then simulated the gas concentration by heavy gas model,last a non-heavy gas model is used to simulate the gas concentration in case of losing the heavy gas effect of the leaked gas.

关 键 词：重气 泄漏 扩散模型
