Objective : to investigate the effect of pumpless portosystemic bypass in clinical piggyback liver transplantation. methods : after catheterized inferior mesenteric vein, the silastic catheter ( filled with heparin saline ) was connected with the catheterized tube of internal jugular vein or subclavian vein in four piggyback liver transplantation patients. the channel was opened after the portal vein was occluded. the portal vein blood poured into the superior vena cava through the pumpless channel. the changes of mesenteric congestion, portal vein pressure, blood pressure and pulse were observed. results : during the occlusion of portal vein, the portal vein pressure was increased greatly, the intestine was congested and swelled obviously and the blood pressure and pulse fluctuated gently. after the pumpless bypass opened, intestinal congestion and swell were abated markedly, the portal pressure, blood pressure and pulse gradually returned to normal range. conclusions : pumpless portosystemic bypass shows a great effect on clinical piggyback liver transplantation. it is a feasible and economical method
目的探討背駝式原位肝移植術中採用體外門-體靜脈無泵轉流的臨床效果.方法4例行背駝式原位肝移植患者，腸系膜下靜脈屬支插管經體外硅膠管（充滿肝素鹽水）與頸內靜脈或鎖骨下靜脈插管相接，在阻斷門靜脈后開通腸系膜下靜脈插管，門靜脈血從體外無泵轉流管流入上腔靜脈，觀察轉流前後腸道瘀血、門靜脈壓、血壓、脈搏等變化情況.結果門靜脈阻斷后腸道明顯瘀血、腫脹，門靜脈壓力明顯升高，血壓、脈搏有不同程度的波動，無泵門靜脈轉流開放后，腸道瘀血、腫脹明顯好轉，門靜脈壓力逐漸恢復正常水平，血壓、脈搏恢復正常.結論背駝式原位肝移植術中體外門-體靜脈無泵流具有方便、經濟、實用等優點，具有良好的臨床效果The merits of dds such as super fine frequency resdutlon 、 high frequency accuracy 、 easy programmed can be in combination with the excellent character of narrow - band tracing filter merits of pll
它可以將dds的超高頻率解析度、高頻率精確度、容易實現程式控制等優點與鎖相環良好的窄帶跟蹤濾波特性相結合。By making full use of favourable narrow - band tracing filter character of pll and by combining the merits of dds such as super fine frequency resolution 、 high frequency accuracy 、 very fast frequency hoping with it, the pll / pll + dds frequency synthesizer presents wide band high quality source and super small frequency hoping step. while the electronically tuned filter abates the image interference and notably improves the selectivity. the theorem of frequency synthesizer and center - frequency - fixed filter is simply but adequately introduced first in this paper
課題中所採用的pll或dds pll鎖相頻率合成方法充分發揮鎖相環良好的窄帶跟蹤濾波特性，並結合dds的高頻率解析度、高頻率精確度和高速頻率捷變等優點，分別實現了系統所要求的高質量寬帶本振源和小步長頻率捷變；採用電調諧選頻技術，則大大改善了接收機的選擇性和抗干擾能力。After strict formal analysis with ban logic, the result have proved that the authentication protocol is secure. the improved access control scheme is realized by the mode of single - key - lock - pair. under new access control scheme, user can own several kinds of access right upon one file under the new scheme without the supposition that the access rights is increase by degrees, and the possibility of overflow problem is significantly reduced by our new method
作為對原雙向認證訪問控制方案的改進，改進后的雙向身份認證協議可以很好的抵抗中間人攻擊和重放攻擊，經過嚴密的ban邏輯形式分析和論證，結果表明該協議是安全的；改進后的訪問控制方案用單鑰-鎖對方案實現，除保持了一般單鑰-鎖對方案的良好動態特性外，在不需要訪問權限遞增假設下，實現了用戶對文件的多種訪問控制權限，並大大減小了溢出問題的發生可能Through the combination of inverter circuit and pll circuit, the process of frequency - tracking is described, and the experimental waves can be reflected perfectly. this provides some experience for the designing and debugging of electrical source
並將鎖相環路與主電路結合起來，觀察到頻率跟蹤的過程，很好的反映了實際波形，為今後該類電源裝置的設計調試提供了良好的前期準備。Lastly, it raises some principalmethods on how to further the reform of our country ' s book distribution, which areto adjust and improve the structure of book distribution, to establish modemmarketing network system, to change the relationship between presses andbookstores, to make publishing and distribution goes well, to change the function " and establish a new pattern of book distribution management, to abide by the rule oflaw in order to construct a good background of book market, and to train andexploit talented persons of book distribution. one of the originality of this thesis is that the topic is very new the reform ofpublishing field, to be exact, began with the reform of book distribution
最後從六個方面提出了深化圖書發行管理體制改革的主要途徑，即加大工作力度，調整和優化圖書發行產業結構；以連鎖經營為突破口，建立現代化營銷網路體系；調整社店關系，實現出版與發行的雙贏：轉變職能，建立圖書發行管理新模式；厲行法治，創造良好的圖書市場環境；樹立人本觀念，做好圖書發行人才的培養、開發和使用工作。本文的創新之處，一是選題富有新意。出版領域的改革，嚴格來說是以圖書發行管理體制改革為切入點而逐步展開的。Abstract : in the paper, dynamic analysis is performed for th e engaging process of the converter lock - up clutch in order to ensure the clutc h engages smoothly, the design approach is proposed for its throttle pressure ch aracteristic and a specific computer program is implemented a numerical example is presented in this paper
