4072.应用于锅炉气热回收中高压蒸发器的SA210钢管的腐蚀失效分析
[通用设备制造业,黑色金属冶炼和压延加工业] [2014-03-25]
The corrosion failure analysis of an SA210 steel used in high pressure evaporator tube is conducted by XRD,SEM,OM.The result shows that the corrosion products in the inner wall of the steel tube is Fe3O4,mainly caused by the residual water in the evaporator tube corroding its inner wall with oxygen after the hydrostatic test of the boiler,finally leading to the corrosion leak of the tube.

4076.基于BP神经网络的CNG汽车注气控制研究
[汽车制造业] [2014-03-25]
Compressed natural gas (CNG) automobile is an emerging new energy car.How to control gas injection is the key technology of CNG electronic control system.At present,the control based on the MAP graph is used usually,but this control method has some shortages,for example larger data,poor adaptive capacity and difficulties in data updating.BP neural network control has adaptive and self-learning,nonlinear processing ability and high generalization,and faults tolerant ability in processing information.In this paper,BP neural network is used to control natural gas injection in order to solve the shortage of the MAP picture control.Simulation experiment shows thefeasibility and advantage of this method.
