A Heat Transfer Model for Emergency Response of Railway Dangerous Goods Transport

On the basis of the influence of railway dangerous goods emergency response center location on transport safety,the similarity between emergency response and heat conduction is analyzed.The heat transfer model for emergency response of Railway Dangerous Goods is established by referring to the Fourer Role.By introducing the concept of emergency response flux and emergency response resistance,the calculating formula is educed.The study shows that the emergency response flux of emergency control center to emergency control spot is in proportion to the emergency response gradient between them and in inverse proportion to emergency response resistance.An applied example indicates that the model reasonable and practical,and the calculation formulas is feasible.
