中文拼音 [rèzhìxiànxiàng]
熱滯現象
英文
thermal hysteresis-
However, in its process of development, china ' s convention and exhibition industry has encountered some undeniable problems, such as fraudulence, overlapping and redundancy, ipr infringement, deficiencies in the management system, lack of legal regulations, overheated exhibition facility construction, disruptive competition and the lagging behind of industrial associations
但同時，當前我國的會展業發展中也出現了一些不容忽視的問題，比如：騙展、重復展和侵權現象時有發生，管理體制不順，缺乏法律規范，展館建設過熱，市場競爭無序，行業組織建設滯后等等。Hysteresis is not only found for the temperatures, due to the difference between the onset and damping temperatures, but also for the input heating power, i. e., the critical onset power is also different with the critical power for the damping process
此外，還發現熱聲起振和消振過程中的臨界溫度和臨界功率都存在滯后現象。基於對滯后現象的分析，提出了一個混合驅動源熱聲驅動器的方案。There are many plants that have the character of time - varying, large delay, large inertia in the process of production of modern power station such as the superheated steam temperature, the reheated steam temperature, the water treatment of boiler and the load regulation. some of them have the strong character of nonlinear and some of them are multivariable coupling systems it is very difficult to obtain good effect of control by conventional pid control. it is necessary to set up the mathematics models of controlled plants if applying control means of modern control theory such as self - adaptive control, optimal control ， decoupling control and predictive control. and these control systems have large calculation and bad character of real time in general. these disadvantages make them be not able to meet the need of real production process and limit the application of them in modern power station. now the generator units are developing towards large capacity and high parameters. many new kinds of generating electricity means are coming into being. the characers of production units of power station become more and more complex but the demand to quality of control becomes more and more strict. the new control means are in bad need to control them effectively
現代電站的生產過程中存在過熱汽溫、再熱汽溫、鍋爐水處理、負荷調節等許多大遲延、大滯后、特性時變的對象，它們中有些還是具有強非線性特性的對象或多變量耦合系統，採用常規的pid控制手段很難取得良好的控制效果。若應用現代控制理論中的自適應控制、最優控制、解耦控制、預測控制等控制手段，則需要建立被控對象的數學模型，而且往往控制系統的計算量大、實時性差。這些缺點使其很難滿足實際生產過程的需要從而極大地限制了其在現代電站中的應用。On the other hand, because of transmission process, large - lag links and complicated on - line analyzer etc, a large number of industrial processes ( in metal engineering, chemical engineering systems, biomedical systems and so on ) can be modeled as time - delay systems. the stability and performance are always dominated by delay phenomena, so the study of delay systems always attracts considerable atten tion in the control theory literature
另一方面，在實際的工業過程中，大慣性環節、傳輸過程、復雜的在線分析儀等不可避免地會導致滯后現象，而這些滯后特性往往會嚴重影響控制系統的穩定性以及系統的性能指標，因此時滯系統的研究同樣具有重要的理論和實際工程意義，而且歷來是控制理論研究的熱點之一。Based on the theory of hydrogen solution in palladium in hydrogen / palladium system and the theory of normal temperature nuclear fusion material and selective resonant tunneling model, some experiment for was carried out producing the " excess heat " and " heat after death " phenomena in ambient condition
基於對氫鈀系統中氫溶於鈀的理論分析，並結合「常溫核聚變材料」理論和「選擇性共振隧穿模型」 ，通過實驗探索產生「過熱」 （ excessheat ）及「滯后發熱」 （ heatafterdeath ）現象的客觀條件。On the other hand, large - lag links, transmission process and complicated on - line analyzer etc, are common in a number of industrial processes, which can cause delay in the systems. such delays will be a main cause of bad performance or even instability for control systems. so, the research on the time delay systems attracts considerable attention in the control theory literature all alone
另一方面，在實際工業生產中，大慣性環節、傳輸過程以及復雜的在線分析儀等不可避免地會導致滯后現象的產生，這些滯后特性往往會嚴重影響控制系統的穩定性以及系統的性能指標，因此對時滯系統地研究也一直是控制理論研究的熱點之一。As the temperature of pyrolysis and the soak time increasing, the carbon materials become more stacked, the specific surface area reduces, both reversible capacity and irreversible capacity decrease, the initial coulumbic efficiency increases, and the hysteresis in the voltage profile between charge and discharge is cut down
隨著熱處理溫度的升高和恆溫時間的延長，所得炭材料的有序化程度增加，比表面積減小，可逆嵌鋰容量與不可逆容量均減小，首次充放電效率增大，電壓滯后現象得到抑制。Based on the heating treatment control system of a spring steel - wire production line in a factory, hubei province, the paper deals with the design of fully automatically monitoring system across its manufacturing process. through research of parameters of temperature control during the period of heating, annealing and tempering in steel wire manufacturing process, the corresponding composite intelligence fuzzy controller is designed. in light with the way of fast heating, a composite intelligent fuzzy controller combined with on - off control & pi control is set up
