该对象是无法应用于的预制件的一部分？

不能应用于的预制件资源示例是不可变的预制件资源，以及具有无效组件（缺少脚本）的预制件资源。
For Prefab contents loaded in Prefab Mode, this method will not check the Prefab Asset the loaded contents are loaded from, since these Prefab contents are loaded into a preview scene and are not part of an Asset while being edited in Prefab Mode. This means that for Prefab contents in Prefab Mode, the method will return true for Prefab instances that have corresponding Prefab Assets that can be applied to, but not for GameObjects or components that are not part of a Prefab instance.
