air pressure head 空气压头
The aerodynamic shape design of train head should consider all kinds of factors because the relation between reducing aerodynamic drag and air pressure pulse may be conflictive and uniform.
减小列车空气阻力和降低列车交会压力波，既矛盾又统一，列车气动头部外形设计需要综合考虑各种因素。
The recuperators have high air resistance , low air preheating temperature and high fan pressure head , and fan has much noise to environment and are apt to break down with vibration .
此换热器空气阻力大，空气预热温度不高，风机压头高，环境噪声大，风机振动大、易损坏。
