中文拼音 [xúnxùyǎnhuà]
循序演化
英文
programme evolution-
In order to maintain the rules conveniently, we make use of the technology of rdbms in managing data, consider the trait of production rules, and then design and realize the arithmetic to check the rules " equipollence and circulation on the basis of our former work - knowledge ordering. all these solve the knowledge base ' s consistency effectively
為了方便對規則的維護，我們充分利用數據庫管理系統對數據管理的巨大威力，結合產生式知識規則的特點，在原有知識序化的基礎上，對規則的等價、循環做了演算法設計與實現，較好地解決了知識庫的一致性問題。The result of the calculation for tip clearance is reasonable when it is compared with theory. two ways are put forward for convention of dimension of the turbine components from high temperature to low one, which is related with tip clearance, a simple example is used to illuminate that the two ways are useful, using the method of design optimization, axiisk and a blade of a certain turhine is analysed, it showes that the method of design optimization is feasible to be used for convertion of dimension of the turbine components. finally, ansys software is used to analyzed the variation of tip clearance with the method of cyclic symmetry analysis when engine works under the conditions of temperature and rotational speed, am using a new method to deal with thermal contact resistance in the calculation
本文完善了計算渦輪葉尖間隙的簡化演算法程序，增加了程序的計算功能，並將其應用於某高壓渦輪進行葉尖間隙分析，所得結果與理論結果進行了對比，得出修改後的程序用於葉尖間隙計算是合理的；同時提出了與葉尖間隙相關的渦輪典型部件的冷、熱態的尺寸兩種換算方法，使用優化設計的方法進行了實例分析，說明了所提出的計算方法是可行的；最後應用ansys有限元軟體利用循環對稱的方法分析了某型發動機高壓渦輪在溫度場及離心力作用下的葉尖間隙在發動機工作過程中變化情況，並分析了計算中的接觸熱阻的處理問題。Matter steadily wrested control of the cosmos away from radiation
物質循序漸進，自輻射手中奪得宇宙演化的掌控權。At last, take a three - storeyed and two - span reinforced concrete frame as example, its damage value under cyclic load at different time is computed by the program. and the damage evolution curve of different element and whole structure is also obtained. as result the damage evolution law of reinforced concrete structure under cyclic load is found, which provides basis for the study of collapsing mechanism of reinforced structure under seismic force
最後，以一個三層兩跨的鋼筋混凝土框架為例，應用作者自編的程序計算了循環荷載作用下該框架結構在不同時刻的損傷值，並給出了其不同構件及整體結構的損傷演化曲線，揭示了循環荷載作用下鋼筋混凝土框架結構的損傷演化規律，為地震力作用下鋼筋混凝土結構的倒塌機制問題的研究提供了依據。分享友人
