本文首先建立了一個簡單的數學模型，考察了直接影響農民農業收入的基本因素，包括：物質資本、人力資本、專業化水平、技術知識和農民數量；進而，從農民是理性經濟人的基本假設出發，指出農民在改進影響農業收入的諸因素方面的消極態度是既定製度約束下的理性選擇? ?現行的農地制度（社會保障制度） 、戶籍制度導致土地產權不穩定、難以流轉和農民數量難以減少，妨礙了土地的規模經營，使農民在物質資本投資、人力資本投資、深化專業化分工、學習和應用技術知識、向城市轉移勞動力方面表現出消極態度。Therefore, it is necessary to take suitable measures to alleviate the influence of flow deflection on the heat - transfer performance of the condenser

所謂泥石流災害管理是這樣一種技術與行為，它通過法律的、行政的、宣傳教育的、經濟制約的或其他的有關手段，監控、約束與引導人們對于災害的反應與有關災害的行為；協調有關災害的各個區域、部門與環節；影響和改善人們的減災觀念；規劃與調整泥石流減災事業的發展目標與相應的背景條件；設計、組織、決策與指揮和城鎮泥石流及有關的重要活動，或通過其他的方法達到有利於系統提高減災效益目的。It tell us : the abrasive capability of fly ash ; the similar calculation of ash erosion ; the calculation of ash erosion in the tube in turn and tube out of turn ; the reason of tube abrasion for gas flue ; the influence of air parameter for fly ash erosion ; the influence of changing temperature ; the influence of the flue gas composition, etc. next, it advances the solving measure ; reduce the flue gas velocity ; reduce the concentration of fly ash ; responsible construction : replace smooth tube with spiral tube ; use the new material of abrasion ; fuel desulfurization ; reduce so3 of flue gas ; raise flue gas temperature, making it up the dew point ; use the abrasion - resistance material to resist abrasion
討論了飛灰磨損性能、管壁受飛灰沖蝕的近似計算、灰粒對順列管和錯列管的磨損計算、煙氣走廊引起對流管束的磨損機理、空氣動力參數對飛灰沖蝕的影響以及受熱面壁溫變化及煙氣成份對飛灰磨損的影響等問題。接著提出了解決的措施：降低平均煙氣流速；降低飛灰濃度；使用鰭片管、螺旋翅片管代替光管；選擇合適的結構及排列方式，減少煙氣中so3的含量；提高受熱面壁溫使之大於煙氣的露點溫度；採用抗腐蝕材料作受熱面等防腐蝕的措施。Under the influence of the submergence the turbulence intensity are quite high at the end stage of burning. however, the turbulence intensity decreases obviously at the medium stage and the preliminary stage of burning because the flow disturbance is eliminated by the mixture of injection flow and main flow
受噴管潛入的影響，結束時刻流場的湍流脈動非常強烈，而中間時刻和初始時刻，由於加質流與主流的強迫混合可以消除氣流擾動向下游的傳播和擴展，流場的湍流脈動明顯減弱。Besides, there are great deals of other questions, which cause various kinds of mechanism of corporate governance unable to play a effective role. at the same time, the article make a deeply analysis to the reasons. finally, the article put forward some advises : reducing the state - owned stock progressively, foster the institutional investor actively, design some encouragement and restriction mechanism to a manager, reform and perfect the state assets management system, perfect regulation system and withdraw mechanism of security market and unifying the stock market progressively, set up powerful security payment mechanism of debts, strengthen restriction of creditor ' s rights of the banks, develop corporate bond financing, and so on
本文以資本結構的基本理論為起點，對各種資本結構理論觀點進行概括，並從股權和債權兩方面分析了資本結構對公司治理的作用和影響效果；通過對國有上市公司的資本結構進行實證分析，揭示了我國國有上市公司的資本結構存在股權和債權結構不合理，股權內部構成和債權內部構成不合理等諸多問題，由此導致了公司治理各種機制的有效作用無法正常發揮，使得公司治理的效應不佳，並進一步對產生這種股權和債權治理效率低下的成因進行了深層次的分析；最後從宏觀和微觀層次，提出對國有股進行有步驟的減持並逐步實現其流通、改革與完善國有資產管理體制、積極培育機構投資者、完善證券市場的法規體系和逐步統一股票市場、建立強有力的償債保障機制、設計經理人激勵約束機制、強化銀行的債權約束、發展企業債券融資等政策建議。The simulation results show that to start the oscillation, the length of the resonance cavity must be well matched with the radial span of the cavity ; mismatch of them will greatly affect the microwave development ; the output power of the microwave in rtto is affected by the microwave mode obviously. under the same conditions, the output power for temooi mode is the highest, and its start and saturation time of oscillation are the shortest. the results also show that the output power will decrease with the increase of the size of the extract window ; the operating state of rtto has great close relationship with the operating current, and there exists an optimum current value
結果表明，束電壓一定時，諧振腔腔長和徑向間距必須良好匹配微波才能起振，匹配不佳會極大地影響微波產生；微波模式對微波產生功率影響很大，同等條件下， tem _ （ 001 ）模式的微波功率最高，起振時間和飽和時間最短；微波輸出功率隨提取口的增大而減小； rtto工作狀態與工作電流的大小關系密切，存在一個最佳工作電流值。The 30mev linac can be used as energy recovery accelerator with photo - cathode rf - gun injector. and multi - cavities photo - cathode injector can not only improve the quality of output electron beam, but also decrease the effect of phase question in the energy recovery process
當注入器束流電子能量接近10mev后，第一加速段與束線中產生的減速相位與加速相位的差是小的，對能量回收效率的影響可以忽略。分享友人
