摘　　要：本文介绍了一款高度同步的电波时钟的设计与制作。设计利用磁棒天线接收国家授时中心发射的68.5kHz长波时间信号,通过单片机进行实时解码,获取时间基准信号,用来校正电波时钟。实验结果表明,该电波钟在教室内使用能够实现显示时间高度准确且同步。An auto diesel engine was broken and damaged badly after being repaired fiom the factory： its piston and connecting rod were also destroyed. The whole engine was scrapped. Who should responsible for this accident, the users or the repair shop？ This paper will help the court to settle the ＂lawsuit＂ according to the just, objective, scientific, and practical technical appraisernent.
