在以後的7個月內, mro將緩慢沉入火星大氣層,並漸漸由橢圓形軌道過渡到距火星表面約185英里300公里的近圓軌道。In this paper, the dynamic characteristics associated with the high - speed maglev vehicle and guideway coupling system has been studied. two issues are discussed : one is the asymptotic stability of the system and the other is the coupling vibration characteristic. the basic relation between the control, structure and coupling parameters is studied emphatically to trace the rule of the vibration and to give help for the design of guideway, vehicle structures and controller
本文選擇高速磁浮列車系統懸浮方向的車軌耦合動力學特性作為研究對象,分析車軌耦合動力學的兩個基本問題:系統漸近穩定性和車軌耦合振動特性,重點研究控制、結構和各種耦合參數與這兩項系統特性的關系,目的在於尋找車軌耦合振動的規律,為軌道、車輛結構和控制器設計提供參考。We extend this result which is similar to ones of hirsch [ 1l ] and jiang [ 2 ] for 3 - dimensional cooperative system. furthermore, in the paper we discusse the cone of km, and obtain the similar result : theorem b : let f be a continuously differentiable cooperative vector field on d, suppose the following conditions hold : ( a ) d is pm - convex ; ( b ) every forward semi - orbit has compact closure in d ; ( c ) there is not more than one equilibrium p, then there is a unique equilibrium p and it is globally asymptotically stable
此外,本文還將在k _ m錐下討論此問題,並得到平行的結果:定理b :設f是d上一個連續可微的合作向量場,假設如下條件成立: ( a ) d是p _ m凸的; ( b ) d中的每一個正半軌道有緊閉包; ( c )至多有一個平衡點p ,則一定存在唯一的平衡點p ,並且是全局漸近穩定的。Asymptotic behavior of almost - orbits of non - lipschitzian continuous semigroups in hilbert spaces
連續半群的幾乎軌道的漸近行為In capter 2, it is proved that the system possesses a global attractor and a two - side estimate for the fractal dimension of it is presented. in capter 3, several different approximate intertial manifolds of the system are constructed by applying linear galerkin method, method of projecting operator and operator eigenvalue and successive iterative method, and it is proved that arbitary trajectory of the system enters into a small neighbourhood of the global attractor after large time. capter 4 studies the asymptotic attractor of the system by constructing a solution sequence which approaches to the global attractor of the equation in long time, and the dimentional estimate of the asymptotic attractor is given
第二章證明了該系統的整體吸引子的存在性,給出了其分形維數的上下界;第三章利用線性galerkin方法、運算元投射和運算元特徵值方法及逐次迭代方法構造了幾類近似慣性流形,證明了該方程的任意解軌道在長時間后進入整體吸引子的任意小鄰域;第四章構造了一個有限維解序列即該系統的漸近吸引子,證明了它在長時間后無限趨于方程的整體吸引子,並給出了漸近吸引子的維數估計Positive homoclinic orbits for a class of asymptotically periodic second order differential equations
