With development of industry, there are a lot of new kinds of physcial models, of these there is one that can not be described only by impulsive differential system. in this case, we should switch to a new set of differential equations taking into consideration momentary perturbations of impulsive nature. a general description of such systems was called impulsive systems with variable structure
隨著工業的發展，出現了許多新的物理模型，其中有一類僅用脈沖微分系統無法恰當地描述，這時，就需要考慮具有瞬時脈沖攝動性質的一族新的脈沖微分方程，對這樣的系統我們一般稱為具有可變結構的脈沖微分系統。The first part, the theory and application about wu - ritt differential characteristic sequence method are discussed, which involves the theories of differential equations, abstract algebra and computer algebra etc. we apply wu - ritt differential characteristic sequence method ( abbr. wu - ritt method ) to linear partial differential equations which has physics significance and give the size of solutions and formal taylor solutions
本文共分兩部分，第一部分討論微分特徵列法的理論和應用問題，涉及到微分方程，抽象代數，計算機代數等重要學科。將吳方法應用到具有物理意義的線性偏微分方程上去，我們給出了型序，驗證了張鴻慶教授八十年代給出的恰當解的概念，刻劃了解的規模並給出了形式冪級數解。The paper hopes to extract a solution of a nonlinear partial differential equation, a quite new model, of low - permeability gas reserves, then studies the penetraial character. the pose of the model has already been proved theoretically [ 4 ], which encourages us to seek an aptitude numerical calculation and to realize the computation
本文希望對一個低滲透氣藏非線性偏微分方程的數學新模型的求解，來研究具有滑脫效應下的滲透特徵，利用模型的適定性在理論上已經獲證的結果，探尋恰當的數值計算方法並且實現編程實現計算機電算化。
