  1. This thesis studies the law of affecting de - noise result and the selection of the threshold and the wavelet function, the combination of wavelet and fft in the fault diagnosis of turbine - generator sets : by the de - noise anslysis of blocks and sin signals, concludes : to blocks signals, usually adopts soft threshold ; the law of affecting de - noise result is when use wavelet auto - de - noise, with the increasing of decomposed level, the de - noise result becomes worse while the level blow the 3, when the level above 3 and when uses wavelet packet, it is the other way round ; the best de - noise methods of the signal is that uses " dbl " wavelet function, three level, soft and " rigrsure " threshold

    本文研究了分解層數對消噪結果影響的規律和閾值、小波函數的選取，結合小波分析與fft分析診斷汽輪發電機組的故障。通過對brocks和sin兩信號的分析，得出：對blocks信號進行分析一般採用軟閾值；分解層數對消噪結果影響的規律為用小波自動降噪在分解層數小於3時，隨著分解層數的增加，消噪結果變好，反之，則變差，用小波包降噪時隨著分解層數的增加，消噪效果變好；適宜選用dbl小波軟rigrsure閾值自動消噪。
  2. On the base of researching the theory of the scheme and analyzing the signal feature, it is obtained that the existence manners and character of distance information in the differential frequency signal. at the same time, a new conclusion is gained that the technology of frequency agility can decrease the constant error of system. it is also to say that frequency agility and frequency modulation fixed - distance fuze has the similar feature to random period frequency modulation fixed - distance fuze. according to the theory of address coding in the hopping - frequency communication, the paper presents the principle of selecting the frequency agility sequence which fit to the radio fuze and constructs the frequency agility sequence family based on the rs codes

    在深入研究方案原理和分析信號特徵的基礎上，獲得了該體制引信差頻信號中，距離信息的存在形式和特點，得出了頻率捷變技術的引入降低了系統定距固定誤差這一新的結論，即頻率捷變調頻定距引信在定距性能上具有類似隨機周期調頻定距的特徵。本文引入跳頻通信地址編碼理論，結合無線電引信的具體特徵，提出了適用於無線電引信的頻率捷變序列的選擇原則，並構造了基於rs碼的寬間隔頻率捷變序列族。
  3. When the frequency of input signal is high enough, we could n ' t capture it by real - time sampling. in this situation, the only choice is equivalent - time sampling. we reconstruct signal with several random sampling series by multi - trigger

    當信號的頻率足夠高時，實時采樣技術已經不能滿足要求，唯一的選擇是採用等價采樣技術：通過多次觸發，用多個隨機采樣序列重建信號。
  4. The selection of the pn sequence is very important because it influences the quality of the channel measurement directly. so it is discussed in this paper. because this system is a set of software radio, that is to say that the system is based on the pc platform and all other function is implemented by programming, so the selection of correlation fast algorithm, which is used in receiver frequently, is also very important

    本文對直序擴頻技術進行了系統地研究，對其中偽隨機碼的選擇直接影響到通道測量的質量的問題進行了討論，因為本系統是一套軟體無線電，即以pc機為平臺，其他的功能都由軟體編程完成，所以對信號接收中大量使用的相關的快速演算法的選擇也至關重要。
  5. Realizes the longitudinal relationship between models by using object - oriented programming language ; 2 ) sets forth the function and software design in detail, and analyzes entities of the system. realizes the randomness of traffic flow and constructs vehicle arriving model, vehicle movement model on road segments and vehicle movement model on intersections, so completes the kernel part of traffic simulation ; 3 ) uses 3d modeling software - multigen creator and real - time simulation software - vega to build up the 3d virtual environment of microscopic traffic simulation, and drives dynamic entities such as driver - vehicle units and traffic lights in static scenes ; 4 ) studies the characteristic of checkerboard system of street layout, analyzes and decomposes the system to deduce a certain simplification method. and researches the application of urban traffic route choice

  6. Because of the difficulty to obtain the traffic flow information of lanes at non - detector intersections in most metropolises of the world, based on the relationships between the lanes of signal - controlled intersections, cluster analysis and stepwise regression are integrated to predict the traffic volume of lanes at non - detector isolated controlled intersections. first cluster analysis is used to cluster the lanes of non - detector isolated signal - controlled intersections and the lanes of all signal - controlled intersections with detectors. then, by the results of cluster analysis, the traffic volume samples are selected randomly and stepwise regression is used to predict the traffic volume of lanes at non - detector isolated signal - controlled intersections. the method is tested by the traffic volume data of lanes of the road network of nanjing city. the problem of predicting the traffic volume of lanes at non - detector isolated signal - controlled intersections was resolved and can be widely used in urban traffic flow guidance and urban traffic control in cities without enough intersections equipped with detectors

    針對目前國內外大中城市中普遍存在的無檢測器信號交叉口車道交通流信息難于獲取的情況，基於信號控制交叉口車道之間的相關性，綜合應用聚類分析和逐步回歸法預測單點無檢測器信號控制交叉口車道流量.首先應用聚類分析將單點無檢測器信號控制交叉口的車道與有檢測器信號控制交叉口的車道交通流量進行聚類，然後在聚類分析結果的基礎上隨機選取車道交通流量樣本運用逐步回歸法預測單點無檢測器信號控制交叉口的車道流量，此方法經過南京市的具體車道流量數據驗證.此類問題的解決，可廣泛應用於城市交通流誘導系統以及交通控制系統
