The temperature distribution on the high temperature side of an electric tunnel furnace is analysed and simulated on the basis of the principle of thermal radiation by the way of thb ( thermal heat balance ). the heated silicon carbon sticks are decomposed into innumerable tiny heating faces, which exchange the heat with the heated materials. a numerical model based on the radiation intensity law is constructed to calculate the energy absorbed by the heated materials and simulated by a computer. the results showed that the even distribution of temperature can be obtained by optimizing the arrangement of the silicon carbon sticks according to the calculation results to make the structure design more reasonable. these calculation results have been used in the practical designs and the expected objectives achieved
利用熱輻射原理,採用熱平衡法對電熱隧道窯的高溫恆溫區溫場進行了分析和模擬.計算中將發熱棒分解為無數微元發熱面與燒結體進行熱交換,依據輻射強度定律,建立了燒結體接收能量的數學模型,並用計算機進行了模擬計算.結果表明,依據模擬結果來優化硅碳棒的排布,可使結構設計更加合理,進而可以獲得分佈均勻的恆溫區溫場.計算結果已在窯爐設計中應用,實踐效果良好Because on one hand such a large number of fer indicates our country has a high ability to make external payment, adjust the balance of payment and intervene into foreign exchange market. the large scales of fer and fdi bring such a hardly estimated value in the expectation of the speculators and the public. they are also the vital reason for our country to confront asia finance crisis in 1998
因為一方面,巨額的外匯儲備標志著我國對外支付、調節國際收支和干預外匯市場的能力大大增強,它和外國直接投資的流入在投機者和公眾預期的形成所帶來的價值是難以估量的,這也是我國較成功地抵禦了亞洲金融危機的一個重要原因。It can be used in any complex environment, can locate all paths from transmitter to receiver which avoid redundant calculation, and it is a standard 3 - d forecast model ; in addition, it is a point to point ray tracing method based on specular theory which do n ' t carry out the receive test ; furthermore the model adopt the reverse arithmetic which exert the tree concept in data frame and establish a virtual fountain tree permanently, the proagmme can back - search the virtual fountain tree when it is running. these operation increase the calculate speed and it result in the higher receive efficiency and precision. the thesis design a programme to compare the prediction results based on ray tracing method of virtual fountain tree between the measurement results and prediction results based on the other transmittion models. the comparsion result indicate the new model is a better model
它可應用於任何復雜的傳播環境中,能找到發射機到接收機之間的所有電波傳播路徑而無須冗餘的計算,是一種準三維的預測模型;另外,從本質上講,它仍然是一種基於鏡像理論的點對點的射線跟蹤法,所以它無須進行接收測試;而且由於採用了反向演算法,運用數據結構中多叉樹的概念,先確定需要計算的場點位置,找出所有能從源點到達場點的射線,並且可一次性建立一個虛擬源樹,以後每次的計算只要通過對該樹進行後序遍歷即可,大大提高了運算速度,因而有較高的接收效率與精度。本文對該模型進行了相應的模擬,並將其預測結果與實測結果以及基於cost231經驗性模型和基於強力射線跟蹤確定性模型的預測結果進行了比較,結果表明了該模型的優越性。The performance detection and analysis of the tags are realized. the reader is integrated with the functions of microwave transmitter, receiver, data collector, digital signal processing ( dsp ), spectrum analyzer, field strength meter, and encoding
