射流纵向通风 meaning in Chinese

ventilation by force draft

The paper involves the research of the application of neural - fuzzy control method to the road tunnel longitudinal ventilation system : by learning the sample data , the neural network automatically produces the membership functions and the control rules , subsequently , the fuzzy control model is easily established ; the distribution of pollutant and the fan operation is simulated under the varies traffic flow circumstances , the simulation results show that the longitudinal jet ventilation in medium - length and long road tunnels can be effectively controlled with the application of above method
本文提出了建立公路隧道纵向通风神经模糊控制系统的一般方法，利用神经网络学习样本数据，自动提取建立模糊控制模型的隶属函数和控制规则，通过模拟仿真各种交通状况下的污染物分布和风机运行情况，结果表明此方法对中长隧道全射流纵向通风具有良好的控制效果。
