日本市场上最近出现一种“电波手表”,据称其精确度极高。10万年误差仅为一秒,终于为多年来的钟表精确度大战画上了句号。　　该“电波手表”每天由天线接收一次日本邮政省通信综合研究所发出的40kHz的标准时刻电波,以该数据为基准,由手表中的微电脑修正时间,从而始终能显示极 Recently appeared on the Japanese market, a “radio watch”, allegedly highly accurate. 10 million years of error is only a second, and finally for many years the clock precision battle come to an end. The “radio watch” received by the antenna every day by the Japan Post and Telecommunications Institute of Integrated 40kHz standard time waves sent to the data as a benchmark by the watch microcomputer to correct the time, which can always display the pole
