解釋
時延因子-
The key technology of it is passive ranging, while the key of ranging is the high precise time delay estimation, which is the main factor that restricts the precision of ranging
其關鍵技術是測量目標距離，而距離測量的關鍵是高精度的時延測量。時延測量精度是制約距離測量精度的主要因素。 -
The terahertz emission, which is a second - order response, and the four - wave mixing signal, a third response, are given the expressions related to the lorentz local field factor l. we found a four - wave mixing signal in the direction 2k2 - k1 for the negative time delay, and the frequency of the four - wave mixing signal has a shift related to the lorentz local field factor l
計算之後，我們給出太赫茲輻射與四波混頻信號關于lorentz局域場因子l的表達式，發現負時間延遲時在2k _ 2 ? k _ 1方向仍有四波混頻信號，其頻率也有所改變。 -
There are two uncertain factor about it : the phase of the pn code and the doppler - shift. after capturing the received signal successfully, the traditional ds receiver always uses a delay locked loop ( dll ) to synchronize the pn code and then uses a costas loop to realize the carrier synchronization. this complex closed - loop structure not only take long time to realize the synchronization, but also has the defect of “ hang up ”
傳統的擴頻接收機通常在捕獲偽碼信號后利用遲早門鑒相的延時鎖定環來實現偽碼的精同步，解擴后利用科斯塔斯環實現載波同步，這種閉環結構不僅同步時間長、結構復雜，而且鎖相環還存在所謂的「 hang - up 」現象。 -
Four criteria are used to evaluate the performance of rescheduling operation : ( 1 ) the average travel time ; ( 2 ) the load factor difference ; ( 3 ) the number of delayed trains ; and ( 4 ) the total delay time of system
而運轉整理策略包含：站間趕點與月臺趕點之趕點策略、抓前車與抓后車之間距控制策略、及刪除列車策略。 -
First, because pipelines are so complex that controlled object is high order, delay, coupling, nolinear and time - varing, it is difficult to realize closed loop control for it using valid mathematic model. to resolve this problem, the paper presents a fuzzy - pid control algorithm with self - adjusting regulation factor. second, if a moving motor supplied by inverter power is switched to be supplied by power supply, the impact of overload - voltage and overload - current appears
主要針對中、大容量供水系統中，由於供水管網鋪設復雜、彎管多、控制對象具有高階、滯后、耦合、非線性及參數時變的特點，難以利用有效的解析式數學模型進行閉環控制，以及多臺水泵並聯運行時，水泵電機由變頻電源供電向工頻電源供電切換過程中產生的過電壓過電流沖擊這兩個難題，提出了可調整因子fuzzy - pid控制演算法及利用鎖相環控制實現水泵電機由變頻電源向工頻電源的同頻同相平滑切換。 -
First the dissertation analyzes and compares the actuality of the performance of the power line carrier network, then put forward the principle of the test system, configuration of the hardware and design of the software of the system. so i analyze the theory of the test system by testing the time delay, and analyze the factor which effect the time delay. then narrate how to test the bandwidth and probability of error - code briefly
論文首先對電力線載波網路性能研究的現狀進行了分析和比較，然後提出本虛擬測試儀的實現原理，硬體的配製以及軟體的設計，接著通過詳細的延時測試說明此虛擬測試儀的運作原理，並分析影響延時的因素。還簡要地說明如何使用此虛擬測試儀對網路帶寬和誤碼率進行測試。 -
