  1. Procreant knowledge expression and forward inference engine are adopted in the method of fault diagnosis based on expert system theory. in the fault diagnosis applying neural network theory, six kinds of improved arithmetic of back - propagation arithmetic, including gradient descent with momentum, variable learning rate back - propagation, resilient back - propagation, quasi - newton, levenberg - marquardt and conjugate gradient, are applied to diagnose the faults of electric load manage center and solid state power controller. different diagnostic results gotten by simulation are compared at last

    在基於專家系統的故障診斷方法中，採用了產生式知識表達和正向推理機制；在基於神經網路的故障診斷方法中，則分別採用了bp神經網路的附加動量法、自適應學習速率、彈性bp演算法、擬牛頓法、共軛梯度法和levenberg - marquardt法對電氣負載管理中心和固態功率控制器的故障進行診斷，並對由模擬得到的不同診斷結果進行比較。
  2. On the contrary, if temperature gradient is relatively low, combustor only undergo low compressive stress at high temperature. the combustor of engine has a longer life length. these results can provide some reference for maintain and design for gas turbine combustor

    分析也表明，若在起動過程中筒壁的溫度梯度較為平緩，火焰筒的氣膜唇邊在起動完成後始終受微小的壓應力作用，火焰筒的壽命可以大大延長。
