It is generally impossible to obtain the analytic optimal guidance law for complex nonlinear guidance systems of homing missiles, and the open loop optimal guidance law is often obtained by numerical methods, which can not be used directly in practice. the neural networks are trained off - line using the optimal trajectory of the missile produced by the numerical open loop optimal guidance law, and then, the converged neural networks are used on - line as the feedback optimal guidance law in real - time. the research shows that different selections of the neural networks inputs, such as the system state variables or the rate of los ( line of sight ), may have great effect on the performances of the guidance systems for homing missiles. the robustness for several guidance laws is investigated by simulations, and the modular neural networks architectures are used to increase the approximating and generalizing abilities in the large state space. some useful conclusions are obtained by simulation results
對于復雜的非線性導彈制導系統，很難求得其解析的最優制導律，只能求得開環的數字解，不能適用於具有時變不確定性的導彈制導系統.利用神經網路的學習和推廣能力，對開環的數字最優制導律進行離線的學習，作為閉環的神經最優制導律在線應用.研究分別選擇系統狀態變量和視線角速率等不同的神經網路輸入對制導系統性能的影響，以及各種制導律的魯棒性問題，並採用模塊化神經網路結構提高神經網路的學習和推廣能力，模擬結果得到一些有益的結論 -
The multipath interference, resulted from interfering between the signals of the line of sight ( los ) and the line of ground reflection in vhf - rc, makes bit error rate of data transmission increased and system reliability attenuated
當前，中國水波中繼通道以直視路徑傳播為主，同時存在地面折射路徑對直射信號產生干涉，造成多徑干擾。這種干擾使得信號傳輸的誤碼率上升，系統可靠性下降。 -
Line of sight is not required, scanning distance is flexible, bulk scanning is possible, read rate is high, and data in tags can be updated
該系統可識別視線范圍以外的東西，其掃描距離靈活且能大量掃描，系統的讀取速度高，並能更新已標簽的數據。 -

With no cure for alzheimer ' s disease in sight, researchers have concentrated on trying to slow the rate at which it corrodes the brain and to postpone its onset
由於目前在治療早老性癡呆病上還沒有什麼好辦法，因此，研究人員的注意力集中於試圖使這種病侵蝕大腦的速度放慢，推遲其開始發作的時間。 -
The robustness of variable structure guidance to line of sight rate measurement noise
視線角速度測量噪聲對變結構制導魯棒性的影響分析 -
The summery and review of exiting exchange rate regime choice theory literature are done in second chapter. among other things, the fixed and floating exchange rate dispute, optimum currency area, open economy macroeconomic model, design of intermediate exchange rate regime, currency crisis model and corner solution, exchange rate regime choice in developing countries and the positive study on exchange rate regime are discussed intensively. one finding is that the mainstream exchange rate regime literatures are always critical to the exiting prevailing exchange rate regime and resort to ever proved unsuccessful regimes to cure the problem in sight
第三章轉向對中國當前匯率制度的分析，在簡略概述其發展演化過程后，對當前我國匯率制度安排的成敗得失進行了評價，指出其基本適應了中國改革開放的需要，在中國避免東亞金融危機中發揮了重要作用，但現存匯率制度在效率、運行成本、對貨幣政策自主性的影響以及風險累積上仍存在著缺陷，這些缺陷在經濟進一步開放條件下有可能成為新的不穩定性因素。
