Unit 1

1.The essence of a game is the interdependence of player strategies.There are two distinct types of strategic interdependence:sequential and simultaneous. 博弈的实质是博弈者采取策略之间的相互依赖性。这种策略性的相互依赖表现为两个不同的类别：连续策略之间的相互作用以及联立策略之间的相互作用。

2.When we say that an outcome is an equilibrium,there is no presumption that each person’s privately best choice will lead to a collectively optimal result. 当我们把博弈的结果表述为一种均衡的时候，并不是基于以下的假设：即博弈的每个参与者的个人最佳策略将会带来共同的最优化结果。

4.Brinkmanship”is the tactic of deliberately letting the situation get somewhat out of hand,just because its being out of hand may be intolerable to the other party and force his accommodation.”

边缘政策 “是一种故意使局势变的有些无法控制的策略，正是这种无法控制性可能会使另一方因无法接受而选择妥协。”

2.The PCMM architecture consists of six main elements:IP endpoints(PC,gaming consoles or SIP phones),cable modem,CMTS(cable modem termination system),record keeping server,policy server and an application manager.

ＰＣＭＭ体系结构包括六个主要组成部分：ＩＰ端点（ＰＣ机、游戏控制器或ＳＩＰ话机）、电缆调制解调器、电缆调制解调器终端系统（ＣＭＴＳ）、记录保持服务器、策略服务器和应用管理器。

2.Reversible computers,or adiabatic systems,recycle their energy to give off extremely little heat,enabling computing power to continue growing where existing technology would falter.

可逆计算机即绝热系统，它能够将能量回收，因此只产生很少的热量，使计算能力在现有计算技术无能为力的情况下继续提升。

3.To stave off these problems,researchers have been investigating alternative computing techniques.Quantrm computing , has garnered significant publicity. 为了避免这些问题，研究人员一直在研究可替代的计算方法。其中，量子计算已

经引起了广泛的关注。

4.Much of the energy needed to make that change is given off in the form of a spark in the case of static enrgy, or heat in the case of circuitry. 发生这一转变所需的能量在静电这种情况下表现为瞬间放电，在电路这种情况下表现为释放热量。 Unit7

1. As with the public network,understanding an individual or device’s physical location will enable a new range of applications that will radically improve existiong business processes and infor mation technologies. 对于公共网而言，了解个人和设备的物理位置会带来一系列新的应用。这些应用将从根本上改进商业流程和信息技术。

4. By comparing the signal strength received from multiple Aps,triangulation can more precisely locate a user.
