此规范是《SCA 装配模型规范》[1]的扩展，定义了 Java 类如何提供 SCA 构件的实现，以及做为一种组件实现类

型的该类在 SCA中是如何被使用的。

此规范需要用到《SCA Java 通用注解注解和 API 规范》[2]中定义的所有注解和 API。在《SCA Java 通用注解和

API 规范》中，所有被引用的的注解和 API 都是定义良好的，除非另行说明。此外在这些 Java 通用注解和 API 规范中

定义的语义都是标准化的。-This specification is the " SCA assembly model specification"　[1] the expansion of definition of the Java class to provide SCA component implementations, and as a component in the realization of such type how the SCA is used. This specification need to use " SCA Java Common Annotations and API Specification notes,"　[2] defined for all annotations and API. In the " SCA Java Common Annotations and API Specification" , all referenced comments and API are well defined, unless otherwise noted. In addition, in the Java Common Annotations and API specification defines the semantics are standardized.
