  1. Compared with the classical bp algorithm, robust adaptive bp algorithm possesses some advantages as following : ( 1 ) increasing the accuracy of the network training by means of using both the relative and absolute residual to adjust the weight values ; ( 2 ) improve the robustness and the network convergence rate through combining with the robust statistic technique by way of judging the values of the samples " relative residual to establish the energy function so that can suppress the effect on network training because of the samples with high noise disturbances ; ( 3 ) prevent entrapping into the local minima area and obtain the global optimal result owing to setting the learning rate to be the function of the errors and the error gradients when network is trained. the learning rate of the weights update change with the error values of the network adaptively so that can easily get rid of the disadvantage of the classical bp algorithm that is liable to entrap into the local minima areas

    與基本bp演算法相比，本文提出的魯棒自適應bp演算法具有以下優點： （ 1 ）與魯棒統計技術相結合，通過訓練樣本相對偏差的大小，確定不同訓練樣本對能量函數的貢獻，來抑制含高噪聲干擾樣本對網路訓練的不良影響，從而增強訓練的魯棒性，提高網路訓練的收斂速度； （ 2 ）採用相對偏差和絕對偏差兩種偏差形式對權值進行調整，提高了網路的訓練精度； （ 3 ）在採用梯度下降演算法對權值進行調整的基礎上，通過將學習速率設為訓練誤差及誤差梯度的特殊函數，使學習速率依賴于網路訓練時誤差瞬時的變化而自適應的改變，從而可以克服基本bp演算法容易陷入局部極小區域的弊端，使訓練過程能夠很快的「跳出」局部極小區域而達到全局最優。
  2. Design considerations of the high power s - band rka are described, by using electron beams of voltage - 600kv, current - 5000a, and the numerical simulations for three kinds of the rka output structures are given. the three kinds of the output strctures are single - gap standing - wave ( sw ) cavity, traveling - wave ( tw ) output structure, and two output structures ( single - gap + traveling - wave structure ). under conditions of using two output structures, the results show that the instantaneous peak power obtained from sw output cavity and tw output structure is respectively 2. 4gw and 2. 1gw, the both power average of 0. 96gw and 0. 93gw, i. e. the s - band rka of two output structures generates peak output power of 1. 89gw at a frequency of 2. 85ghz

    從數值模擬中得到雙輸出結構的微波功率輸出結果為:駐波輸出的瞬時功率為2 . 4gw （周期平均為0 . 96gw ） ;行波輸出結構輸出瞬時功率為2 . 1gw （周期平均0 . 93gw ） ，就獲得了頻率為2 . 85ghz的微波輸出。本文簡要的描述了電磁軟體（ magic ）對速調管輸出腔體進行了模擬，並對相應的模擬方法進行了評述。
