+The Window Manager subsystem provides basic capabilities of window management. It is the basis for UI display.
 The Window Manager subsystem enables multiple applications to use the same physical screen for display and interaction. For each application, you need to design the interaction interface in the fixed window area. A window acts as a display container of the application interface, and the Window Manager subsystem organizes the interaction interfaces into a form visible to end users.

+**窗口子系统**提供窗口管理的基础能力，是系统图形界面显示所需的基础子系统。
 窗口系统的作用，是提供一种机制，让多个应用界面复用同一块物理屏幕进行显示和交互。每个应用程序中，需要实现固定窗口区域内的交互界面设计，窗口作用应用界面的显示容器，而窗口系统负责将这些交互界面组织成最终用户见到的形态。
