By analyzing the puissance, experience, body and happiness language, i find that the really meaning of the female fashionable periodical is a kind of contradictive expression. it is a sign of status, but also is a reversed discrimination ; it wants be out of the traditional culture, but also in it ; elegant feminine temper is also in the charge of the masculine society ; happiness is based on the expenditure of body and substance. now the contradictive expression of feminine language is becoming the most important problem in the development of the female fashionable periodical
筆者通過對女性時尚期刊權力、經驗、身體、快樂話語的解構和分析，發現女性時尚期刊的表達陷入了一定的話語矛盾和困境:是身份認同的標志，卻又隱含著反向歧視;經驗話語的「反文化」表達，實質上是建立在「泛文化」基礎上對傳統文化的部分回歸;優雅可人的女性氣質，說到底卻帶著男性規訓的深深烙印;快樂話語的傳播，是以對消費主義的追隨和女性身體的消費為前提的。Presents the model proposed for analyzing the vibration characteristics of shrouded blades and their calculation method by employing a wave propagation theory and modal synthesis technology coupled with a finite element method from the view point it is possible not only to conduct frequency modulation of the shrouded blades of a gas turbine, but also to utilize the friction effects between them to dissipate energy, thereby attaining the aim of vibration alleviation, as shrouded blades have been widely used in the design of high - speed turbomachinery, such as modern gas turbines and steam turbines, and with the shrouded blades forming an integral whole in a centrifugal force field, the vibration characteristics of the whole ring of blades are different from those of a single isolated blade, and this makes it essential to take into account the integral effect of blade shrouds, concludes from the calculation examples and engineering application that the above approach is valid and correct along with the possibility of considerably reducing the scale of calculation and analysis, and points out it is necessary to take into consideration the coupled effect of the whole ring of blades while the dynamic characteristics of shrouded blades is being analysed
帶冠葉片不但能調頻，還可以利用葉冠之間的摩擦效應來耗散能量，達到減振的目的.帶冠葉片在離心力場中形成一整體，其整圈葉片振動特性不同於單個孤立葉片，需考慮葉冠的整體效應.利用帶冠葉片系統的循環對稱性，提出了採用波傳播理論和模態綜合技術，結合有限元方法研究燃氣輪機帶冠葉片振動特性的分析模型和計算方法.算例和工程應用證明了該方法是效性的、正確的，並可以大大降低計算分析規模.研究表明帶冠葉片動力特性分析時必須考慮整圈葉片的耦合效應
