张工应邀为一炼钢厂的中心机房设计设备方案。其现状是:机房处于车间附近,车间具有很高的温度,所用设备具有很强的交流电流;控制系统基于计算机网络实现数据传输、存储;约有2000个监测点(通过多台PLC设备实现),每个监测点每2ms采集一次的监测数据,数据量是4字节,通过网络发送到网络中心,并以文件形式被保存到文件服务器上,所有监测数据需在服务器上保存半年以上;对各种设备的控制信号通过同一网络传输到各监控点上;各种监测数据可在异地通过公用网络同步查看并进行实时分析。张工的方案中,将设备分为了三类:一是服务器类,设计了文件服务器、数据库服务器、控制服务器、监控服务器等四个主要服务器;二是网络设备类,设计了一个路由器、5台千兆交换机等主要设备;三是辅助类,包括UPS、机房监控系统、空调等主要设备,另外计划配置有关的软件系统。 如文件服务器的存储系统采用容量为1TB的硬盘,以RAID5冗余模式构建,则应配置的硬盘数至少为述基旦之(40),优先采用的结构是(41)。 监控服务器负责接收、处理监测数据,其恰当的机型是(42)。 所配置的监测数据分析软件应具备的最基本功能是(43)。 交换机最必要的配置是(44)。 根据上述需求,至少应增加的一台设备是(45)。 空白处(45)应选择()

Observation of spontaneous social activity, most productively carried out in certain kinds of psychotherapy groups, reveals that from time to time people show (76) (notice) changes in posture, viewpoint, voice, vocabulary, and other aspects of behaviour. These behavioural changes are often (77) (accompany) by shifts in feeling. In a given individual, a certain set of behavioural patterns corresponds to one state of mind, while another set is related to a different psychic attitude, often not (78) (consist) with the first. These changes and differences give rise to the idea of ego states.The position is, then, that at any (79) (give) moment each individual in a social aggregation will exhibit a Parental, Adult or Child ego state, and that individuals can shift with varying degrees of (80) (ready) from one ego state to another. These observations give rise to certain (81) (diagnose) statements. "That is your Parent" means : "You are now in the same state of mind as one of your parents or a (82) (parent) substitute used to be, and you are responding as he would, with the same posture, gestures, vocabulary, feelings, etc. " "That is your Adult" means: " You have just made an autonomous, objective (83) (appraise) of the situation and are stating these thought-processes, or the problems you perceive, or the (84) (conclude) you have come to in a non-prejudicial manner. "That is your Child" means: "The manner and intent of your (85) (react) is the same as it would have been when you were a very little boy or girl. " 85()
