彩雲下，空曠的紫藍色的天幕上，一剎間，吐出一點紫紅，緩慢上升，逐漸變成小弧、半圓；變成桔紅、金紅；然後微微一個跳躍，拖著一抹瞬息即逝的尾光，一輪圓圓的紅日嵌在天邊。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。The method of picking up synchronizated signal is digital phase - locked loop, which is picking up phase information from the suddenly toggle between codes
提取碼同步信號一般採用鎖相環技術，利用碼元間存在的瞬間跳變獲取需要的相位信息。Solving the rate equation numerically, the influence of the factor a and the reflectivity r on the transient characteristics of the ecld has been analyzed when the shape of the hysteresis loop looks like a parallelogram approximately

動態電流監測器能瞬時反映出負載跳變狀態，更容易判斷手機板的故障部份。In chapter 3, first we answer the open problem of williams ( 1979 ). we solve the problem completely when q - matrix is totally stable or uni - instantaneous, that is, we not only prove the existence of q - function but also identify the q - function. second, for invariant distribution of jump processes, we also obtain some good results
第三章首先回答了williams （ 1979 ）開問題，對q -矩陣為全穩定和單瞬時情形，完整的解決了該問題，也就是說，不僅證明了q -函數的存在性，而且還把具體的q -函數構造出來了；其次對跳過程的不變分佈，也得到了很好的結果。Chapter 4 is dedicated to the study on - invariant distribution. first, as q - matrix is totally stable or uni - instantaneous, we prove the existence of - invariant distribution of q - function and identify the q - function. second, we generalize - invariant distribution to jump processes and obtain some good properties and results
第四章致力於-不變分佈的研究，首先對q -矩陣為全穩定和單瞬時情形，證明了q -函數-不變分佈的存在性，並且也把具體的q -函數構造出來了；然後把-不變分佈推廣到跳過程，得到了一些較好的性質和結果。分享友人
