An improved high fan-in domino circuit is proposed.
设计实现了一种改进的高扇入多米诺电路结构。
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。
As the bypass ratio of turbofan engine is more and more high, fan noise is a more important part to the overall turbofan engine noise.
随着飞机广泛使用的涡轮风扇发动机涵道比的不断提高，风扇噪声在飞机总噪声中占有越来越突出的地位。
