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 ) simulation of the heat transfer across the walls : there are two methods, finite thickness solid method and semi - infinite solid method, to simulate the heat transfer across the walls when the temperature gradient along the height and the width of the wall is ignored
在火災環境下，忽略高度和寬度方向的溫度變化，採用一維熱傳導方程，建築、圍護結構適用兩種傳熱模型:有限厚度模型和半無限大厚度模型。 -
In this dissertation, mgo5 is introduced to form solid solution to restrain the decomposition of at in high temperature. then at is mixed with the al2o3, forming gradient composite to raise the integral intensity of the material and not affecting the thermal properties. the experimental results show that the additive mgo5 can effectively restrain the decomposition of at and promote the sinter process, which enhances the density of at
本文在充分分析本領域國內外研究現狀的基礎上，首先通過引入添加劑鈦酸鎂（ m2t ） ，使其與鈦酸鋁形成固溶體，以達到抑制鈦酸鋁中溫分解的目的；再通過與強度高、氣密性好的氧化鋁進行梯度復合來提高整體材料的強度並能彌補鈦酸鋁滲透性能差，同時對材料的低熱膨脹性能影響不大。
