Abstract : in the internal circulating fluidized bed, there exist the moving zone, fluidizing zone and heat transferring zone with different fluidized air velocities. the convection heat transfer coefficient of immersed tube in the heat transferring zone is impacted by the velocity of the moving zone nearby and its data and change trend are obviously different with those of the common bubbling bed. the maximum heat transfer coefficient is evidently higher than that of the bubbling bed. as the bed materials have not been fluidized in the heat transfer zone, the coefficient has increased highly. the curve of that changes gently, feasilble to control the combustion intensity in the fluidizing zone
文摘:垃圾焚燒系統中，內旋流流化床存在不同布風速度的移動區、流動區和換熱區，處于換熱區的埋管的對流換熱系數受附近流動區氣流參數的影響，其變化趨勢及數值大小與普通鼓泡型流化床之間有明顯不同：最大的對流換熱系數明顯高於鼓泡床；換熱區尚未流化時，對流換熱系數已經大幅提高；整條換熱曲線的變化比較平緩，易於流化床濃相床內換熱。A coke oven represents a kind of controlled object with a full spectrum of closely coupled factors, such as distributed parameters, no - linearity, time - dependent change and multi - variable features. among them, the discharge header pressure and fan suction are key parameters, and also constitute strongly coupled variables with very close inter - relation, which are fulfilled by the way of regulating coal - feeding and the rate of primary air supply in practice
焦爐是一個分佈參數，非線性、時變、多變量緊密耦合的被控對象，其中集氣管壓力和鼓風機吸力既是關鍵參數，又是具有緊密關系的強耦合變量，它們均是通過調節給煤量和一次送風量來實現控制的。The wind rates of roots blower with these various kinds of three - lobe circular arc rotor are calculated and comparison between their performances is carried out. it is found that three - lobe rotor with external - internal circular arc and cycloid can produce the largest air volume. comparing the air pulsation produced by cylinder rotor and helix rotor, and proof that the structure of helix rotor can reduce the noise of roots blower
本文給出了羅茨鼓風機三種不同的圓弧轉子型線的參數方程（外圓弧及其包絡線型、內圓弧及其包絡線型、和內外圓弧加擺線型） ，還給出了這三種轉子的徑距比（ r _ a a ）的極值，並進行比較，得到：內外圓弧加擺線線型是最優線型這一結論；為降低羅茨風機的噪聲，將傳統的直葉轉子改成扭葉轉子。From the macro - aspect, the commercial medical insurance is just started in china, but with the improvement of the market and the support of our government policies the commercial health insurance face the good opportunity to develop. it has enormous potential market as well. from the micro - aspect, the mount of commercial health insurance products are great, but the liability covers are not enough. insurers can not effectively control the risk, which leads to the higher payment. further more, the entries of foreign insurance companies because of wto enlarge the competition. the potential demanding of health insurance is plenty, but the virtual demanding is lack. all of this indicates that every participator need more improvement to advance the commercial health insurance market
從宏觀層面來看，我國的商業健康保險起步較晚，尚處于起步階段，但隨著市場的不斷完善、國家政策的鼓勵和支持，也面臨著難得的發展機遇，市場潛力巨大。從微觀層面來看，在市場供給方面，商業健康保險的產品數量較多，種類卻比較單一，保險公司風險管控能力薄弱，賠付率居高不下，我國加入wto后，由於外資保險公司的進入，行業競爭加劇;在市場需求方面人們對健康保險潛在需求較大，但有效需求不足。因而各市場參與主體還需逐漸成熟以促進健康保險市場的進一步發展。The main conclusions are as follows : to reconstruct agricultural wholesale market systematical, to attach importance to the link between the wholesale market and administration for industry & commerce, to establish rational inspection sample cost pay system, to update inspection machine, to increase inspection precision and varieties, to promote risk management level and stuff training, to dispose unqualified agricultural products in the market strictly, to publicize the food safety information as the price and quantity information, and to encourage general citizen to take party in supervise
主要結論為：建立系統化的農產品安全檢測體制，重視批發市場與工商局等政府部門之間的協調與合作，制定合理的檢測樣品費用支付制度；借鑒先進的檢測手段和方法，更新技術設備，提高農產品檢測精度，增加檢測品種；進一步提高風險管理水平和檢測人員的素質；對不合格的農產品要採取嚴格的處理措施；與市場價格，交易數量一樣，公布安全檢測信息，大力鼓勵普通市民參與監督。分享友人
