工程项目划分的目的（）。 A.有利于工程项目的开工申报和对前阶段工程项目施工履约情况进行评价 。 B.有利于工程项目施工过程质量检验和工程项目竣工验收 。 C.有利于以单元工程为基础对经施工质量检验合格的己完工程项目进行计量支付 。 D.有利于工程项目合同支付、施工进展、施工质量、施工安全信息的分类管理和统计分析 。 E.有利于工程项目施工安全及现场文明施工的管理。 Given: Which two statements are true?（） The output could be 8-1 7-2 8-2 7-1。 The output could be 7-1 7-2 8-1 6-1。 The output could be 8-1 7-1 7-2 8-2。 The output could be 8-1 8-2 7-1 7-2。 【背景资料】某9层住宅项目，某装饰施工单位负责内外装饰装修，装饰内容较多，竣工后不久发现部分楼层水泥砂浆地面大面积起砂、空鼓、裂缝，外墙砖空鼓、脱落等。 请根据背景资料完成相应小题选项外墙砖粘贴前找平层及饰面砖不得淋水湿润，确保其干燥。 教师为什么要进行课堂观察和课例研究。 A system is being planned with three production partitions, one each for an IBM i, AIX standard edition, and Power Linux applications. One fibre-channel attached TS3100 tape library will be shared between the partitions for backup. Which solution provides tape library sharing with minimum operator intervention?（） Configure VIO Server Express Edition to control the tape library through one fibre channel card.Assign the library to the production partitions when needed.。 Configure the IBM i partition to own the tape library.Use IBM i virtualization to host a virtual tape library connection to the AIX and Linux partition.Assign the library to the production partitions when needed.。 Configure a fibre channel card for each partition， and a configure fibre switch.Connect the partitions and tape library to the switch.Zone the switch so all partitions can enable the tape when needed and disable the tape when finished.。 Configure AIX to control the tape library through one fibre channel adapter.Use AIX virtualization to host a virtual tape library connection to the IBM i and Linux partitions.Assign the library to the production partitions when needed.。
