第 4 讲;UNIT 2 科技英语基础知识（二）;本讲内容; Accurately synchronized clocks are crucial for many applications in sensor networks. Existing time synchronization algorithms provide on average synchronization among all nodes, however, as we show in this paper, close-by nodes in a network may be synchronized poorly. The Gradient Time Synchronization Protocol (GTSP) is proposed which is designed to provide accurately synchronized clocks between neighbors. GTSP works in a completely decentralized fashion: Every node periodically broadcasts its time information. Synchronization messages received from direct neighbors are used to calibrate the logical clock. The algorithm requires neither a tree topology nor a reference node, which makes it robust against link and node failures.;;本讲内容;表数词的前缀 “一半，1/2”;“semi – ” 用来构成各种新词: semiconductor 半导体 semicircle 半圆 semifinal 半决赛 semiautomatic 半自动的 semi-skilled半熟练的 semi-civilized 半??明的 semi-official 半官方的 ;表数词的前缀 “一”;表数词的前缀: “一”;表数词的前缀: “一”;表数词的前缀: “二”;表数词的前缀: “二”;表数词的前缀: “三”;表数词的前缀: “四”;表数词的前缀: “1/4”;表数词的前缀: “五”;表数词的前缀: “六”;表数词的前缀: “七、八、九”;表数词的前缀: “十”;表数词的前缀: “百”;表数词的前缀: “千”;表数词的前缀: “千”;America’s plans didn’t seem to interest the eastern hemisphere.
