Aiming at such problems in combustion system of homemade middle and miniature boiler, as a complex system with the character of dead zone, time variation, serious non - linearity, large time delay, coupling and a lot of disturbance, this paper presents a new set of optimal control resources. by using well - matched control method on system, stable automatic running is realized. having the serious divulgence coals difference a lot from each other in character, instability of chemistry, value of lowest emission of heat, home - made boiler controller is not at all ideal. instead of traditional model that controls the ratio based on proportional control or with the correct signal of the amount of oxygen, this paper, combined with intellect control theory - - fuzzy control and self - optimizing concept, propounded a kind of fuzzy self - optimizing controller to be used in air supplying system of the boiler, and expatiates on the idea of dividing the control process into two parts, dynamic and static to realize, thus meets the demand of homemade boiler economic running
本設計針對國產中、小型電站鍋爐燃燒系統參數時變、嚴重非線性、干擾因素復雜、耦合嚴重、模型不易確定的特點，提出多變量協調控制方案，解決了系統可控性差，難以實現穩定自動運行的問題；在此基礎上，改變以往以煙氣含氧量控制送風的傳統模式，針對國產電站鍋爐設備主體及一、二次送風迴路泄露嚴重，煤種混雜、成分不穩定、燃燒發熱值低、燃燒效率不高等問題，應用智能控制理論中的模糊控制技術，結合自尋最優控制的思想，設計了一種模糊自尋優控制器，應用在電站鍋爐送風控制系統上，並闡述了動靜態兩種實現途徑，通過在線優化風煤配比，實現最佳經濟燃燒，切實保障了鍋爐的經濟運行。 -
The terahertz emission, which is a second - order response, and the four - wave mixing signal, a third response, are given the expressions related to the lorentz local field factor l. we found a four - wave mixing signal in the direction 2k2 - k1 for the negative time delay, and the frequency of the four - wave mixing signal has a shift related to the lorentz local field factor l
計算之後，我們給出太赫茲輻射與四波混頻信號關于lorentz局域場因子l的表達式，發現負時間延遲時在2k _ 2 ? k _ 1方向仍有四波混頻信號，其頻率也有所改變。 -
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。 -
This projection takes into account the effects of aerosols which tend to cool the climate as well as the delaying effects of the oceans which have a large thermal capacity. however, there are many uncertainties associated with this projection such as future emission rates of greenhouse gases, climate feedbacks, and the size of the ocean delay. . etc
這預計已考慮到大氣層中懸浮粒子傾于對地球氣候降溫的效應與及海洋吸收熱能的作用（海洋有較大的熱容量） 。但是，還有很多未確定的因素會影響這個推算結果，例如：未來溫室氣體排放量的預計、對氣候轉變的各種反饋過程和海洋吸熱的幅度等等。 -
Thereby, it is no time to delay to inspect and prevent automobile emission pollutant, while, in order to do better the work, we must do better automobile emission inspection firstly
所以對汽車排氣污染物的監控與防治已處于刻不容緩的地步，而要搞好汽車排氣污染物的監控與防治，首先必需做好汽車尾氣的檢測工作。
