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 -

對籃球運動員身體素質訓練內容的特徵進行分析后認為，身體素質的可訓性、 「模糊性」 、可兼顧性及基礎性是運動員在進行身體素質訓練時必須加以正確認識的重要因素.對這些特徵進行分析，可以為教練員、運動員科學的認識專項身體素質訓練的內涵提供新的理論認識基礎 -
( 3 ) on the basis of the deletion analysis, three substitution mutants ( ml : 6bp sequence upstream of gcc box m2 : gcc box and m3 : g box - like sequence ) by pcr were designed to isolate the essential ja - responsive element. transgenic tobacco plants containing promoter substitution constructs were generated by agrobacterium - rnqdiaied leaf transformation. loss - of - function experiment, using transient expression analysis of gus reporter genes, confirmed that gcc box act as an essential element to respond ja signaling in pdf1. 2 promoter
（ 3 ）在缺失突變的基礎上，通過對gccbox及其相鄰的上下游六個堿基進行取代突變，將突變啟動子與gus構建融合基因，在煙草中受heja誘導的瞬時表達結果表明， h1和m3的突變對該啟動子應答ja信號的影響很小，而m2 （ gccbox的突變）則幾乎使該啟動子應答ja信號的功能完全喪失，所以gccbox是該啟動子中應答ja信號的必需元件。 -
