  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. In reference [ 4 ], anderson extened the result of hayman from the viewpoint of exceptional set, and put forward a question whether the exceptional set can be expanded into innumerable discs. langley and zhan xiao ping have made great efforts to solve the problems of exceptional set of functions such as fk, fkq [ f ] and fkq [ f ] + p [ f ] etc., obtained comparatively complete result, and given positive answers to anderson s questions. but these result arc only concerned with entire functions due to the difficulty caused by poles

    Langley 、詹小平等做了大量工作，解決了形如f ~ k ， f ~ kq [ f ] ，及f ~ kq [ f ] + p [ f ]等函數的例外集問題，得到了比較滿意的結果，肯定地回答了anderson等人提出的問題，但這些工作基本上局限於整函數，主要原因是極點帶來了很大的困難，對于亞純函數的例外集的研究，詹小平取得了新的進展（見文14 ） 。
  3. A note on the concept of vague sets

    關于局部極小值點為整體極小值點的函數的一點注記
  4. Moreover, the longitudinal piece is higher twist ( suppressed by a factor i / a / 2 ). the dipole cross section is largely unknown, only at small distance p it can be expressed in terms of gluon density

    偶極截面只有在小距離時才能表示成膠子密度的函數，在整個范圍內求解偶極截面，需要解非常復雜的演化方程，目前是不能做到的。
