3. Energy consumption of heating rooms will increase when air exchange rate become large. because the mechanisms of heating methods used currently, such as radiator heating, ceiling heating and warm - air heating, are different from each - other, the indoor thermal environment is not the same when each one of them employed for room heating. for enhancing energy efficiency of heating rooms, indoor thermal comfort and energy saving effects should be investigated when natural ventilation is used to make a good air quality indoors
   房間換氣次數的增加勢必導致供暖房間能耗加大，頂棚 輻 射 、散 熱 器和 熱 風等三種採暖方式由於供暖機理不同，形成的室內 熱 環境特徵不同，通風換氣時產生的通風 熱 損失也有所區別，為了提高大換氣量房間的供暖節能效果，必須對不同供暖方式在大換氣量情況下的 熱 舒適性與節能效應進行研究。
4. It is very difficult to analyze flame radiation in the cylinder of a diesel engine by theoretical method since flame radiation is a function of many parameters, such as the combustion process, the geometrical description of the chamber, the soot formation and oxidation processes, the soot radiant temperature and soot absorption coefficient. the radiant property of the flame in a cylinder is dependent on the combustion process. but the thermodynamic state of real engine cycles can be analyzed from the pressure - volume diagrams in the cylinder. thus a new thermodynamic computational model is set up for the flame radiation in the cylinder of a diesel engine based on the indirect relationship between the flame radiation and the pressure - volume diagram of the combustion process in this paper. the flame radiant heat flux in the cylinder of a di diesel engine is calculated with the variation of crank angle by this model. compared with measured values, the result of the computational values shows the model is available to represent the effects of flame radiation
   柴油機缸內的火焰 輻 射 受諸多因素的影響，用理論分析法來確定它是相當困難的，由於柴油機缸內火焰 輻 射 特性依賴于缸內的燃燒過程，而燃燒過程中的實際 熱 力狀態又可用示功圖來分析，因此藉助於火焰 輻 射 與缸內 熱 力參數之間的這種間接關系，建立了一種計算柴油機缸內火焰 輻 射 傳 熱 的新模型，利用該模型對一臺直噴柴油機缸內火焰 輻 射 熱 流量隨曲軸轉角的變化情況進行了計算，將計算結果與實測結果進行了比較，表明該模型能較好 預 測缸內火焰 輻 射 傳 熱 量。
