論文第三章針對組成系統的各個模塊進行了機理建模，並且通過matlab軟體中的simulink圖形化模擬環境進行了本課題系統的模擬研究，主要針對影響系統特性的主要參數變化，動態分析系統的輸出特性，在上下行工況中，分析了電機軸系粘性阻尼系數、軸系摩擦力矩、主迴路蓄能器迴路液壓泵馬達內泄漏系數、蓄能器氣體容積、液壓缸柱塞粘性阻尼摩擦系數以及不同運行樓層工況等參數對系統特性的影響；最後對軸向柱塞泵馬達的流量壓力脈動對電梯轎廂速度的影響和蓄能器內油液體積損失機理進行了理論研究。Unlike inverters for general purpose, auxiliary inverters of subway vehicle have the characters of high power, wide range of high dc input voltage, entirely sealed electronic units and natural cooling. single pulse width modulation ( pwm ) technology is found to be optimal by comparing several different high power inverter technologies and is utilized in the 2 - channel staircase inverter discussed in this thesis
針對地鐵車輛輔助逆變電源的大功率、直流側輸入電壓高且變化范圍寬、輸出電壓穩定且波形質量高，電子部件全密封且要求自然冷卻的特點，分析比較了幾種大功率逆變器技術方案，選擇單邊脈寬調制階梯波合成逆變器為研究對象。If the ability to " brain scan " individuals expands from the million or so currently under scrutiny to include all inhabitants of the planet ( as per the echelon surveillance system which already monitors all private / commercial telecommunications ) then no - one will ever be able to even think about expressing an opinion contrary to those forced on us by the new world order
如果「腦掃描」個人的能力擴張到數兆或如此多現在正被詳細檢查的，包括所有的地球上的居民（按照梯形監測系統，它已經監測所有私人商業電信） ，接著沒有一個將永遠能永久的思考關于壓榨一個意見相反的到那些通過新世界的秩序強加於我們。Soon after the earthquake, sister jiang received a call from mrs. hwang, who told her that when the quake began, together she and her husband had prayed to master for help, then they led their three children, aged seven, five and three years, downstairs through a broken stairwell, crawling out to safety through a hole that was formed when a metal door had been crushed and twisted. mrs. hwang expressed her gratitude for these arrangements that seemed to have been made especially in order for her family to escape. even though her house lay in ruins, she decided to be initiated as soon as her family was resettled
災后不久，師姊接到了黃太太打來的電話，告訴她事發當時，她們夫妻同聲祈求清海師父幫忙，竟然能帶著三個分別為七歲五歲三歲的小孩，從斷裂開來的樓梯走下，又能從被壓擠變形的鐵門中的一個好像早已挖掘好的小洞爬出，讓她們一家五口得以逃生，真是感激莫名，雖然家已毀了，她決定等家裡安置好了以後，要去印心了！Buckling analysis of simply - supported piezoelectric functionally gradient rectangular thin plate
四邊簡支壓電功能梯度矩形薄板的屈曲Fault location is an importrant function in distribuiton automation. in the thesis, the transferred information from feeder terminal unit is computed with load ’ s trapezoid fuzzy figure. the fault location is affirmed by the result of computation using the trapezoid fuzzy math theory. the atp and matlab softwares are used to simulate the 10kv lines in urmuqi distribution network. and the results shows the reliability and accuration of the method in the thesis
線路故障定位是配電自動化的一項重要功能，文中提出利用線路始端電壓、電流和線路ftu （饋線終端單元， feederterminalunit ）的上傳信息，結合配電變壓器負荷的梯形模糊數模型，運用模糊數學理論通過電流計算來進行故障定位的新方法。分享友人
