英文摘要Subject： 英文摘要 Subject： A Study of accessing cross-language of GASOR with Object·oriented Technology Speciality： Computer Application Technology Name： Quan Instructor： Wang ABS’I’RACl’ At present，implementing models with different language is becoming natural direction in application system．In object layer，how to access cross language among models诵th object—oriented and how to adopt reasonable method are the crucial and difficult issue in application system．Accessing cross language which based on object is a mutual capability that carl communicate with the models of different language．The object should be defined with favorable interface which Can insure the consimency of itself．The key issue is how to maintain the consistency in communication．It can conduce to erlhance the rate of reutilization and improve efficiency of development． Firstly,according to the methodology of object-oriented，diversified accessing cross language technologies which exist are studied．And three forms of accessing cross language technology which exist currently are summed up．The research of the mutual communication by the style of C function，the COM interface and the platform of．NET are analyzed．Then the advantage and disadvantage of those three forms of accessing cross language technology is discussed． Secondly，considerring the actual problem of the reservior object model of GASOR and the characteristic of itself,the feasibility of the accessing cross language technology is analyzed and the technical theory connect、析th the the reservior object model of GASOR is studied．Accessing cross language technology in the reservior object model of GASOR includes two aspects．One is the C++object model based on the native code，the other is the C群 object model based on the．NET managed code．The reservior object model of GASOR is the C++object model，and the C撑code can only communicate、)I，iⅡl the．NET managed code．Thus， indirect layer is needed to establish a bridge between the C++object model and th
