通过一个高涵道比涡扇发动机故障诊断的实例分析，验证了三层逆传播网络的可行性。
The case study of a high bypass ratio turbofan engine has verified the feasibility of a three-layer back propagation network.
最近的高涵道比涡轮风扇，例如罗罗的遄达发动机，推动空气通过发动机核心周围的空气相较于通过核心气量9倍。
The latest "high bypass" turbofans, such as the Rolls-Royce Trent, push around nine times more air around the core of the engine than through it.
此外，由于引擎（发动机）外部运动较慢的空气覆盖了高温燃气排出引擎后部时的噪音，“高旁道比”（高涵道比）飞机的噪音指数下降了80%左右。
They are also some 80% quieter because the mass of slower-moving air shrouds the noisy hot gases coming from the rear of the jet.
