Radiation spectrums of relativistic charged particles in a dipolar magnetic field were studied numerically in detail by using the current density of moving charged particles in this paper
摘要從運動的荷電粒子產生的流密度出發,研究了在地球偶極磁場中運動的相對論性荷電粒子的輻射能量譜,並對其進行數值計算。Compared with traditional air - conditioning, its advantages lie in thermal comfort energy efficiency free use of spacing and etc. this paper introduces the procedure and the result of the experiment of gas - heater radiant floor system and gshp radiant floor system and compares them with traditional air - conditioner. based on the analysis of the heat transfer of radiant floor, this paper uses the theory of heat transfer to establish a mathematical model and computes it with difference equation. the important factors inferred from the model such as floor surface temperature heat intensity composite heat transfer coefficient deviate from the experiment result in a small range of 20 % and fit the need of the practical use
在分析了輻射地板傳熱機理的基礎上,文中利用熱傳導、大空間的自然對流換熱等傳熱學理論建立了輻射地板的傳熱模型,再採用有限差分方法對模型求解,所得有關輻射地板供冷熱性能的重要參數如地板表面平均溫度、熱流密度、地板表面復合換熱系數等與實測值相差在20以內,滿足工程使用要求;同時得出輻射地板盤管供水溫度是影響地板供冷熱性能的重要因素的結論。
