  1. This scheme integrates universual data accesss technology of microsoft, which plays a more and more important role in three - lay c / s ( client / server ) and uses the technology of ado ( active data access ), adopts the asp script language in display the results and uses stored procedure of sql server in databases design. in the system of b / s, client realizes a high efficient access to the server database through displaying diversified active controls in browser and using ado to access the data source. the disposing of data accures under the database not in the font of this system. this kind of scheme cannot only bring the system a higher real time response, but also decrease data runoff of the networks, lower the possibility that web server becomes bottleneck of the system and make the system more transplantable

    當前的web數據庫訪問技術正處于發展階段，針對這種情況，本文通過分析當前各種流行的web數據庫訪問方案的優缺點，結合在三層次的c / s系統中扮演越來越重要的角色的中間件技術，採用了microsoft公司所提出的一致數據訪問技術，利用ado控制項，結合當前的asp語言，底層數據庫採用了sqlserver7 . 0的存儲過程技術，設計了一種自己的web數據庫訪問方案，即在browser / server系統當中，客戶端通過顯示在瀏覽器中的各種activex控制項，通過了ado連接數據庫，數據的處理利用了存儲在數據庫內部執行，實現對後端數據庫的高效訪問，並且這種方案在給系統帶來較高的實時響應性能的同時，減少了網路數據流量，降低了web服務器成為系統瓶頸的可能性，也增強了系統的可移植性。
  2. The subject inducts digital time division technology ( pwm ), which is more advantageous at the accuracy and the predigest of hardware than simulant multiplication. what they call measuring power energy reasonably is that measuting except harmonics power energy fed back power. yet it realizes reasonable measurement of power energy which measures by base wave ac parameters method base on digital time division

    本課題引入了數字時分割（ pwm ）脈寬調制技術，在測量的準確性、硬體電路的簡化等方面都比模擬乘法器具有較高的優越性。所謂合理的計量電能，就是不計非線性負載回饋給電網的負的諧波電能，而採用基於數字時分割的基波交流參數測量的方法，真正實現了電能的合理計量。
  3. Numerical simulation results indicate that, for low temperature dust particles, dust particles mainly exist in the area near the column center and their charge - number can be considered as a constant, while in the area where there are no dust particles, ion and electrons are in ambipolar diffusion ; for high temperature dust particles, both the distribution regions of dust particle and high ion density are expanded and dust charge - number is increasing with the distance from the center

    計算結果表明：當塵埃粒子的溫度較低時，塵埃粒子主要集中在圓柱形放電器的中心很小的區域，塵埃粒子攜帶的電荷幾乎是一個常數，受塵埃粒子空間電荷的影響，離子在該區域的密度最高。在遠離中心區域，離子和電子呈現雙及擴散特點；當塵埃粒子的溫度較高時，塵埃粒子分佈的區域和高離子密度區域擴大，塵埃粒子離放電器中心越遠，攜帶的負電荷越多。
  4. In order to save and use electric energy reasonably and effectively. it is necessary to measure ac electric parameters accurately and real - time, so the rapid development of industrial production requires measuring instrument with high level. during the operation of industrial devices, it demands real - time, on - line measurment of the multi - parameters for crect operation. therefore, power system and users demand urgently a new type of safe, reliable, real - time and high - speed measuring instrument of ac parameters

    為做到節約電能併合理高效地利用電能，這就需要對電量參數進行準確、實時地檢測，因此，對測試計量儀器也提出了越來越高的要求。許多工業設備在運行過程中，需要對其進行實時在線測量，隨時了解其各種電量參數。所以電力系統以及電力用戶都迫切需要一種安全可靠、實時快速的交流電量綜合檢測儀器，有效地對電量參數進行測試。
  5. In large rotating machinery using filmatic bearing ( turbogenerator, air compressor, etc. ) there is a potential trouble from impefect installation or running conditions, a metals " contact between rotors and shells. the trouble is usully called rubbing. the advantage of ae technologe in the rubbing diagnosis and early detection is showed. instead of classical ae characteristic parameters ( counts, amplitude, energy, duration and the other ones ) a new feature extraction by frequency analysis of ae envelop signals is discussed. both research of ae process and field experements indicate that periodic components in the envelop spectrum related to rotational speed increase evidently at the beginning of rubbing production, hence are highly sensitive to the rubbing fault diagnosis. according to the new design an acoustic emission equipment for the rubbing diagnosis named buaa ae testing system is developed and described

    汽輪發電機、空氣壓縮機等採用油膜支撐的大型轉動機械，由於安裝或運行中的原因，在轉子旋轉過程中，可能和器壁發生輕微的摩擦和碰擊，簡稱碰摩.聲發射技術在碰摩發生特別是故障早期診斷上有優越性.本系統的特點是沒有沿用傳統的計數、幅度、能量和持續時間等聲發射特性參數，而是在聲發射包絡信號的頻率分析中進行特徵提取.聲發射發生的過程分析和現場試驗都表明這種方法對碰摩檢測很敏感，在碰摩發生的起始階段，包絡譜中與轉速同步的周期性分量顯著增加.根據這種新的設計思想自行研製了buaa碰摩聲發射檢測儀並對此作了介紹
  6. In experiment the control object is boiler, and the designed fuzzy controller is used to control the real - time system. the effect of the simulation and real - time control is better, which proves good characters and the correctness of the structure analysis of the designed controller, and also manifests that using the structure analysis method can direct the design of fuzzy controller and supply the theory basis

    選擇實驗裝置中鍋爐為控制對象，將本文中提出的具有等比間距隸屬函數的模糊控制器組成控制系統對鍋爐水溫進行溫度實時控制，模擬和實時控制實驗均取得了良好的控制效果，由此證明該控制器的優越性，同時也證明解析結構分析結果的正確性，這表明運用模糊控制器的解析結構分析可以指導完成模糊控制器的設計，並為其提供理論基礎。
  7. In this thesis, we used the q - switched nd : yag laser pulse focused by lens to pump the cr ~ ( 4 + ) : mg _ 2sio _ 4 crystal, with the pump laser pulse duration and energy of 30ns and 50 mj separately, and got the laser pulse with center wavelength, pulse duration and energy of 1. 22 m, 8. 2 ns and 10 mj on the best work condition. on the base of zhangguowei s approximation about gain - switching and the parameter of cr ~ ( 4 + ) : mg _ 2sio _ 4 crystal, we calculated the time characteristics of cr ~ ( 4 + ) : mg _ 2sio _ 4 laser pulse with rate equation by numerical method, obtained the conclusion that the laser pulse duration is only related to the pump energy and cavity length : the larger the pump energy is, the narrower the pulse duration is ; the longer the cavity is, the wider the

    本論文採用調qnd : yag脈沖激光通過透鏡聚焦后縱向抽運cr ~ （ 4 + ） : mg _ 2sio _ 4晶體，抽運光脈沖寬度為30ns 、能量為50mj ，在較佳工作條件下得到了中心波長為1 . 22 m 、脈寬為8 . 2ns 、能量為10mj的激光脈沖;並在張國威分析增益開關時間特性的近似法基礎上，結合實際的cr ~ （ 4 + ） : mg _ 2sio _ 4激光器的相關參數，從速率方程出發，用數值計算的方法更為精確的模擬了cr ~ （ 4 + ） : mg _ 2sio _ 4激光器輸出激光脈沖的時間特性，得出了激光脈寬只與抽運能量、腔長有關的結論，即抽運能量愈大，脈寬越窄;腔長越長，脈寬則愈寬。
