  1. Nevertheless, as the simulating technology involves the integrated high - techs and knowledge of computers, networks, images and graphs, multi - medias, software engineering, information processing and automated control, the simulating system is affected by its own characteristic - featured conditions, running environment and training requirements, thus yielding many problems that exist in our marine engine room simulators being currently used. for example : the mers system has poor working stability and high rate of breakdown ; its viewing device is yet to be updated, as the true aspect of the engine room can not be seen during training ; the teaching display board can not display the running state of the system with 3 - d animations, neither can it change the dynamic flow chart, etc. the afore - said problems have been greatly retarding the seafaring teaching and training, and restricting the application value of mers, as a consequence

    但是,由於輪機模擬器模擬技術綜合了計算機、網路技術、圖形圖像技術、多媒體、軟體工程、信息處理、自動控制等多個高新技術領域的知識,模擬系統受到了其特有的制約條件、運行環境和訓練要求的響,現行輪機模擬器在應用中還存在著許多問題,如:輪機模擬器系統工作穩定性差,故障率高;視景裝落後,訓練中見不到機艙真面目;示教板不能用三維動畫來示設備運行狀態,不能更動態流程圖等。
  2. Our aim is to provide reference data for the mechanism of the effects of ree on crops and the safety evaluation of re used in agriculture. 1. in soil culture experiment, re applications with appropriate dose in dry condition increased the contents of soil available n, whose no - effect value were 505mg / kg at eighth week, whereas higher levels of re had negative effects, re applications with both appropriate and higher dose in inundated condition reduced the contents of soil nh / - n and hydrolysable n. re treatment concentrations showed significant positive correlation with the contents of soil exchangeable re. and significant negative correlation with the contents of soil available p and soil ph value. there was no significant effects of re on soil exchangeable cations, but applications of re increased the contents of soil water soluble cations, especially that of ca2 * and mg2 +

    兩種培養條件下,稀土處理濃度與土壤交態稀土含量成正比,與有效磷含量、土壤ph成反比,對土壤交態鹽基離子含量無響,但通過作用增加了水溶態離子,尤其是ca ~ ( 2 + ) 、 mg ~ ( 2 + )離子的含量;第二周稀土處理增加交態zn含量,對交態fe有降低作用,旱培條件下增加交態mn含量,淹水條件下對其有降低作用;第八周稀土處理均提高交態fe 、 mn 、 zn含量,其機制主要與稀土降低土壤ph有關。
  3. A novel strip - coil - baffle structure used to enhance heat transfer and support the tube bundle for a tube - shell heat exchanger is proposed. the new structure can sleeve the tubes in bundle alternatively to create a vortex flow in a heat exchanger. the numerical simulation on the flow and heat transfer characteristics for this new structure heat exchanger is conducted. the computational domain consists of two strip - coil sleeved tubes and two bare tubes oppositely placed at each corner of a square. the velocity and temperature fields in such strip - coil - baffled channel are simulated using fluent software. the effects of the strip - coil - baffles on heat transfer enhancement and flow resistance in relation to the reynolds number are analyzed. the results show that this new structure bundle can enhance the heat transfer coefficient up to a range of 40 ? to 55 ? in comparison with a bare tube bundle ; meanwhile, higher flow resistance is also accompanied. it is believe that the strip - coil - baffled heat exchanger should have promising applications in many industry fields

    介紹了一種用於強化管殼式熱器殼側傳熱和支撐管束的螺旋折流片新型結構,該結構是對熱器管子相間地套上螺旋折流片以產生旋渦流動.研究模型是在正方形布的4個管子中的2個對角管子套上螺旋折流片后形成的通道,利用fluent軟體對該上述四管通道模型的流場和溫度分佈情況進行了數值模擬;分析了四管通道模型中螺旋折流片對強化傳熱和流動阻力隨雷諾數的變化關系的響.算例結果示該新型結構可比相同尺寸的光管通道中的情形傳熱系數提高約40 ? 55 ? ,同時也將伴隨較高的流動阻力.可以相信螺旋折流片式熱器將會在許多工業領域有良好的應用前景
