摘　　要：介绍了3种蒸气云爆炸后果预测模型,分别是TNT当量模型、多能法、Baker-Strehlow模型。阐述了这些模型的基本原理,将3种模型进行了对比研究,并将3种模型的无量纲距离和超压关系绘制在了同一图中。对某一蒸气云的爆炸后果进行了预测,并对结果进行了分析,指出了不同模型的优缺点。This paper introduces three kinds of models for predicting the strength of blast of Vapor Cloud Explosion, including TNT model, Multi - Energy method, Baker- Stmhlow model, dcscribs the basic principles of these models and Compares the similarities and differences of the models. The dimensionless overpressure versus energy scaled distance of these models is drawn in in one figure, the consequence of one kind of VCE is predicted, the result is analyzed and the advantages and disadvantages of the different models are found out.
