例如，当连接的设备电池电量变化时，应用程序可以接收到广播通知，从而可以通知用户或者采取其它必要的措施。
For example, an application could receive broadcasts that indicate a connected device's battery level and could notify the user or take other action as needed.
许多广播由系统发起——比如，宣布屏幕已关闭，电量不足，或者照片被捕获的广播通知。
Many broadcasts originate from the system-for example, a broadcast announcing that the screen has turned off, the battery is low, or a picture was captured.
中国国家能源局下发的该通知取消了103个计划或在建项目，涉及未来120吉瓦的火力发电量。
The announcement, made by China's National Energy Administration, cancels 103 projects that were planned or under construction, eliminating 120 gigawatts of future coal-fired capacity.
