It is by now a well established fact that the overwhelming hazard from fire is smoke as far as the death of people in the fire is concerned.There are many methodologies for addressing the smoke toxicity component of fire hazard such as CO stochastic model,FED(fractional effective dose)model,FEC(fractional effective concentration)model,N-gas model and so on.None of these models can reflect spatio-temporal variation of the smoke concentration.A new dynamic smoke toxicity evaluation model,RRC(respiration,route and concentration)model,is proposed in this paper concerning the three decisive factors in real fire such as the respiration,movement route of people and the distribution of smoke concentration in the building.Furthermore,an example of the model is presented.

There are many methodologies for addressing the smoke toxicity component of fire hazard such as CO stochastic model, FED ( fractional effective dose) model, FEC (fractional effective concentration) model, N-gas model and so on. Neutral of these models can reflect spatio-temporal variation of the smoke concentration. A new dynamic smoke toxicity evaluation model, RRC (respiration, route and concentration) model, is proposed in this paper concerning the three decisive factors in real fire such as the respiration, movement route of people and the distribution of smoke concentration in the building. Future, an example of the model is presented.

教师与家长建立良好的关系是顺利开展教育教学工作的前提。教师与家长之间的关系是微妙的,有时教师一个无意的表情或姿势,一句无心的话,就可能让教师和家长之间有了心结,影响家园之间的沟通与合作。  我带的班里有个名叫率率的男孩,他机灵帅气,活泼大方,刚入园时也不像大多数孩子那样大哭大闹,我们都觉得他是个挺让人省心的孩子。谁知,没多久我们接二连三地接到了率率妈妈的投诉。  ●“为什么你对我的孩子不理不睬?”
