最大放熱速率 的英文怎麼說
中文拼音 [zuìdàfàngrèsùlǜ]
最大放熱速率
英文
maximum heat release rate-
It ' s the first time to explore the combustion characteristics of lpg / diesel mixing fuel engine, and find that, with the change of load and rotation, the changing trend of the ignition delay period of e10 mixing fuel is almost as identical as that of the diesel, but that of e30 mixing fuel is very different. comparing with diesel, the combustion of e10 is improved slightly, but that of e30 greatly changes ; the maximum eruptive pressure decreases ; the maximum pressure increase rate decreases ; the highest releasing heat rate increases ; the highest combustion temperature falls ; the ignition delay period extends
結果表明: e10混合燃料與柴油的著火滯燃期隨負荷和轉速的變化趨勢基本一致; e30混合燃料與柴油則有所不同; eio混合燃料發動機的燃燒與純柴油相比，略有改善; e30混合燃料的燃燒特性發生明顯的變化，最高爆發壓力下降，最大壓力升高率減小，最大燃燒放熱率增大，最高燃燒溫度下降，滯燃期延長。The analysis starts from the introduction of the theory of exchange rates and the relevant economic factors that affect exchange rates. the analysis is based on the following theories : the theory of macro - stabilization policy in open economy, the mundell - fleming model, originated by professor robert a mundell of the department of economics columbia university, who also founded the theory of the optimum currency areas ; another theory is the trilemma by paul krugman. it is concluded that the current stable exchange regime serves as an important guarantee for the fast economic development in china
面對「人民幣是否應該升值」這個國內外經濟界討論的熱點，本文從匯率決定理論及影響匯率制度的相關經濟因素出發，引用了最優貨幣區域理論的首創者、美國哥倫比亞大學經濟系教授羅伯特? a ?蒙代爾的開放條件下宏觀穩定政策的理論「蒙代爾?弗萊明模型」以及克魯格曼的「三元悖論」等理論來探討人民幣匯率制度的選擇及未來匯率體制的發展目標和前景，明確了目前穩定的人民幣匯率體制是促進我國經濟高速發展的重要保證。Engine operating conditions cold be changed quickly and are very bad sometimes, such as : from suddenly cranking to driving in winter, acceleration to sudden torque demand. in the light of zero emission vehicles, in order to achieve better hot efficiency, maximum power, higher safety and best emission, engine controls become more and more difficult. automotive engines are typical nonlinear, time - delay, time - varying parameter systems
汽車發動機使用環境變化大，使用條件有時非常惡劣，從寒冷的冬天突然啟動進入行駛狀態，行駛過程中的突然加速，急劇的扭矩變化等等，在這樣的條件下，為了使其熱效率、輸出功率、行駛性、安全性和排氣清潔性處于最佳狀態，給汽車發動機的控制帶來了極大的困難，特別是零排放汽車排放標準的提出，對發動機控制提出了更高的要求。
