根據(jù)CORBA規(guī)范，闡述了橋接組件的體系結構和六種橋接模型，并引申出八種橋接方式，比較了各種橋接方式的性能差異，利用自定義橋接組件，把建立在UNIX平臺上的系統(tǒng)擴展為跨UNIX和Windows平臺的分布系統(tǒng)。經(jīng)測試驗證，系統(tǒng)符合設計的要求，改善了原系統(tǒng)的不足。

Abstract According to the specification of CORBA, the architecture of bridge component and six kinds of models of the bridge were expatiated. These models lead to eight ways to create the bridge component. After analyzing the performance of these kinds of bridge, a user-defined bridge was applied to create a distributed system under UNIX and Windows that was originally set up under UNIX. The system was testified to be successful.
Key words bridge; component object model; common object request broker architecture; interface description language; interface; distributed system
