  1. Considering the weakness of the solar - power adsorbers in refrigeration / air conditioning, such as the effects of heat collecting in desorption period and heat loss in adsorption period, here, a new adsorber is proposed ? ? evacuated tube which is cooled by water. simulation calculations and experiments have been performed. with a view to the intermittent characteristics of solar - powered adsorption, a continuous cycle operation for the adsorption refrigeration cooling system with active carbon fibre ( acf ) - methanol adsorption refrigeration working pair is carried out

    本文針對目前太陽能固體吸附式製冷系統中吸附集熱床在解吸階段集熱效率不高和在吸附階段散熱效果不理想的狀況，以及針對太陽能固體吸附製冷系統循環的間歇性，本文提出了一種新型吸附集熱器:真空集熱管?水冷型吸附集熱器，以活性炭纖維?甲醇為工質對實現連續製冷循環方式，並對其進行了相關的性能實驗和數值模擬計算。
  2. During flight of a solar powered aircraft, latitude and direction are changing at all times, therefore the optimal latitude and the optimal direction at different period is developed

    太陽能飛機在飛行時，飛行緯度和太陽方位角都在隨時發生變化，所以本文著重討論了每個時段使太陽能飛機獲得最大輻射量的緯度和方向（太陽方位角） 。
