- When you try to run a unit back, or micromanage it around to flank, you’ll often find it moving slowly because it insists on running from cover to cover. 当你操作一个单位撤退，或用微操使他从侧面突击，你常常发现他移动很慢因为他坚持要笔直走。
- Trainees are drawn from infantry, engineers, and signal units. 士兵都是从步兵、工兵和通信兵里面选拔。
- Signal unit initial alignment - invokes initial alignment prior to activating or restoring a signaling link. 信令单元初始定位 -- 在激活或恢复信令链路之前调用初始定位。
- At last,an example of IF unit of radar echo generator system based on DDS is presented.This signal unit can generate radar IF echoes including general pulse,LFM,NLFM,PSK. 最后给出了一个基于DDS的雷达多目标模拟系统中频单元的设计实例,该单元可以灵活生成包括常规脉冲、线性调频、非线性调频、相位编码在内的雷达中频回波信号,为被试雷达提供较为全面的测试环境。
- They pushed Manchester United back with their sheer force and I can see them pegging Arsenal back here as well. 他们曾用自己强盛的攻击力把曼联送回家，我也可以看到他们以同样的方式送走阿森纳。
- Stapleton knows exactly what it is like to fall out with Arsenal following his controversial move to Manchester United back in 1982. 斯塔普勒顿很明白同阿森纳闹翻是一种什么样的滋味。他在1982年因此而完成了一笔颇富争议的转会，由阿森纳去了曼联。
- There are three different types of signal units differentiated by the value contained in the Link Indicator field. 有三种不同的信令单元链路，可根据指示器字段所含的值进行区分。
- Elsewhere on this day in LFC history Liverpool cruised to a 2-0 win over European champions Manchester United back in 1968. 在利物浦历史上，1968年的今天利物浦2-0战胜了欧冠冠军曼联队。
- These signal units are used to bring a link up or down and verify that it is working correctly. 这些信令单元用于建立或撤消某个链路并验证链路是否正常工作。
- MTP Level 2 messages are placed into the MTP Level 2 signal units for transport across the link. MTP 第2级的消息会放置在MTP 第2级的"信令单元"中以便在链路上传输。
- The neurons are the dynamically polarized cells that serve as the major signaling unit of the nervous system. 神经元是动态极化的细胞，并且是神经系统中的主要信号物质。
- MTP Level 2 messages are placed into the MTP Level 2 signal units?for transport across the link. MTP 第 2 级的消息会放置在 MTP 第 2 级的"信令单元"中以便在链路上传输。
- Message Signal Units (MSU) - transport user information received from the SCCP, ISUP or the MTP 3 layers. 消息信令单元(msu)--传输从sccp、isup或mtp第3层收到的用户信息。
- MSUs are the only signal units that are retransmitted if they are received in error. MSU 是信令接收出错时仅传输的信令单元。
- A host of missed chances at Old Trafford ultimately led to the Reds' downfall, although poor refereeing decisions held United back in a game that appeared set for nothing other than a home win. 曼联还要继续争取成功卫冕联赛冠军，而球队在冠军杯也杀入四分之一决赛，弗格森希望这场失利能让球队在赛季余下的比赛中会有焕然一新的表现。
