  1. With fast development of our country " s gas industry and air ' s increasingly serious contamination in city, using gas instead of coal and supplying energy in high efficiency and cleanliness has become necessary way in city. there are different problems in the current heating ( air conditioning ) systems. in the cogeneration system, heat and power affect each other, heating - pump heating ( aie conditioning ) system can not satisfy the peak load very well, the cost of gas fuel in boilor heating sestem is so high. the high generating efficiency of the diesel - engine two - sourse heating ( air conditioning ) systems is limited in range of 100kw - 1000kw, the heating scope is so limited. combined cycle of two sourse heating ( air conditioning ) system is most suitable selection to buesness community with big scope my paper aim at this syetem ' s primary question when it is applied in our country - - - - bringing project into execution and technology economy feasibility and off - design performence, combined with a certain demonstrating project in beijing buesness community, going along with calculating and analyzing, drawing out some efficient datas and conclusions, based on this, bringing out primary alements affecting combined cycle of two sourse heating ( air conditioning ) system " economics

    熱電聯產系統熱電相互牽連，熱泵供暖（空調）系統不容易很好地滿足尖峰負荷，鍋爐供暖系統供熱中天然氣燃料構成的成本過高，內燃機雙源供暖（空調）系統的高發電效率僅限於100kw - 1000kw負荷范圍，供熱面積有限。對于大面積的商業園區、居民小區，燃燒天然氣的燃氣-蒸汽聯合循環雙源供暖（空調）系統是最佳選擇之一。本論文針對該系統在我國應用時的主要問題- - -方案的技術實施與技術經濟可行性，結合北京某一商業園區示範工程，進行了系統的計算與分析，得到了有效的數據與結論，在此基礎上，提出影響聯合循環雙源供暖（空調）系統經濟性的主要因素，並進行敏感性分析，得出有益的結論；最後通過各種供暖方案的比較分析回答了某些人對該系統的疑慮和不解，並指出系統的優化方向。
  2. We would concentrate on using energy more efficiently and on substituting noncarbon renewable or nuclear energy sources for fossil fuel ( coal, oil and natural gas ? the primary sources of manmade atmospheric carbon dioxide )

    我們應該致力於將能源做更有效的運用，並以無碳再生能源或核能取代石化燃料（燃煤、石油與天然氣，是大氣中人造二氧化碳的主要來源） 。
  3. After conversion these primary energy sources deliver roughly 300, 000 petajoules of so - called final energy to customers in the form of electricity, gasoline, heating oil, jet fuel, and so on

    這些初級燃料在轉換之後，產生約30萬拍焦耳的最後能源，以電力、汽油、燃油、噴射燃料等形式，供應給使用者。
  4. For this reason the chinese government has identified lng as a priority source of china s future energy needs and plans to increase the use of natural gas from the current three per cent of the primary fuel mix to six per cent by 2010 and 10 per cent by 2020

    由於這一原因，中國政府將液化天然氣做為中國未來能源需求的首選來源，並計劃將天然氣的用量從目前占燃料總量3 %的比例增加到2010年的6 %和2020年的10 %
  5. For this reason ， the chinese government has identified lng as a priority source of china ' s future energy needs ， and plans to increase the use of natural gas from the current three per cent of the primary fuel mix to six per cent by 2010 ， and 10 per cent by 2020

    由於這一原因，中國政府將液化天然氣做為中國未來能源需求的首選來源，並計劃將天然氣的用量從目前占燃料總量3 %的比例增加到2010年的6 %和2020年的10 %
