  1. Firstly, second harmonic component ratio and dead angles of two phase inrush ' s dispersion in three - phase transformes are acted as input variable. secondly, the method applies improved algorithm based on the original algorithm of multi - layer forward back propagation network, that is to say, adding last variational effect of weight value and bias value to this time and making use of variable learning rate. at the same time, this method also adopts dynamic form in the number of hidden floor node

    首先，文中將三相變壓器兩相涌流差流的二次諧波含量比和間斷角作為網路的輸入變量；其次，利用對原有bp網路訓練演算法基礎上的改進型演算法（即在計算本次權值和閾值的變化時增加上一次權值和閾值變化的影響以及採用變學習率，與此同時隱含層神經元個數採用動態形式） ，通過樣本訓練使網路結構模型達到最優。
  2. At the same time, dispersion of different stokes number particles influenced by the ordered large - scale turbulent structures of the carrier gas phase was investigated. and the following " conclusion was drawn : particles of mediate stokes number mainly concentrated in the outer boundary region of large scale eddies, and they had the nignest dispersion rate ; particles or little stakes number mainly lay in the core region of the eddies, and they had the lest dispersion rate ; though particles of large stokes number distributed throughout the eddy structures

    同時還模擬研究了不同stokes數顆粒在二維流場旋渦擬序結構作用下的運動擴散特性，詳細描述了不同stokes數顆粒在流場中的空間分佈規律，認為：中等stokes數顆粒集中於流場旋渦的外沿區域，在流場空間中的擴散率最高；小stokes數顆粒集中於流場系列旋渦的渦核區域，在流場空間中的擴散率最低；而大stokes數顆粒則遍佈於流場旋渦渦核和渦外沿區域。
  3. At last, three - dimensional mathematical model of gas - particle two phase turbulence was established, and it was adopted to study the gas - particle two phase rectangular jet as well. the distribution of the time - averaged velocity and turbulence intensity was studied, and some of the simulation results were compared with the experimental results ; the coherent structure of flow field was described in the three direction, the evolution and motion of the eddies was discussed too ; the dispersion of fine particles in the three dimensional space was also investigated

    全面地分析了矩形射流氣相時均流場的速度、湍流強度的空間分佈規律，並就部分數值模擬結果與實驗結果進行了對比研究;描述分析了氣相流場湍流擬序結構，對流向、橫向和展向三個方向旋渦的空間結構特點進行分析研究，並分析了流向渦隨時間變化的發展、運動規律。
  4. A perturbation method by tight - binding approximation which provide the relation of phase constant and angular spectrum of fields of in - waveguide is presented. the strip width of phase constant can be given. on the other hand, the group delay - time due to the k dispersion in single - mode transmission can also be estimated

    提出一種利用緊束縛近似的微擾法計算陣列波導的相位常數與輸入光角譜的關系，由此算出相位常數的帶寬，並利用衍射方法估算單模傳輸中k色散引起的群延時。
