+### 各Context区别
+
+[ApplicationContext](../reference/apis-ability-kit/js-apis-inner-application-applicationContext.md)是应用级别的上下文。每个应用可以由一个或多个HAP组成。[AbilityStageContext](../reference/apis-ability-kit/js-apis-inner-application-abilityStageContext.md)是HAP级别的上下文。每个HAP可以有一个或多个UIAbility和ExtensionAbility。[UIAbilityContext](../reference/apis-ability-kit/js-apis-inner-application-uiAbilityContext.md)是UIAbility的上下文。[ExtensionContext](../reference/apis-ability-kit/js-apis-inner-application-extensionContext.md)是ExtensionAbility的上下文。系统会为每个UIAbility默认生成一个Window。每个Window通过loadContent加载页面，生成一个[UIContent](../reference/apis-arkui/js-apis-arkui-Content.md)（ArkUI实例）。每个UIContent对应一个[UIContext](../reference/apis-arkui/js-apis-arkui-UIContext.md)。
