The other day, I happened to meet someone I hadn’t seen for many years. I couldn’t believe the change in him. In fact, he didn’t even seem like the    21   person.
When I first knew Bill , back in   22 , he was one of the most carefree(无忧无虑)people I had ever    23  . He was always ready to have a party. He thought    24  of going out for beer at three o’clock in the morning or driving 15 miles to see an old   25   he really liked.
Bill and I were in the same class in college, and    26   was never dull when he was    27  . With him there was one wild    28   after another. Sometimes I wonder how we    29   to study for our exams.
Last week I was in Houston on business and I ran into Bill in the bar at the hotel.   30  , I wasn’t even sure it was    31  . Was this short-haired businessman really the same person? I wasn’t really sure until I came near him but it indeed was Bill. Now he works for a bank. He    32  most of the evening about his job, his new car and his house. How he had changed! Back when we were in college, the    33   thing Bill cared about were possessions(财富). Now they seemed to be his main    34  .Although I have changed quite a bit myself, somehow I never    35   Bill changing so much. My image of him   36    the one I had formed     37  the time when we were college students together.
I suppose it’s   38    to expect people to remain the same, especially    39   I have changed so much myself. But I must say that I enjoyed the old Bill much more than the new Bill. Maybe he    40  the same way about me.

题型:单项选择题

其施工单位承建一南方沿海城市的大型体育馆机电安装工程。合同工期为10个月,于2004年11月10日开工,2005年9月10日竣工。
该工程特点是各类动力设备包括冷冻机组、水泵、集中空调机组、变配电装置等,均布置在有通风设施和排水设施的地下室。
由于南方沿海空气湿度高、昼夜温差大,夏天地下室结露严重,给焊接、电气调试、油漆、保温等作业的施工质量控制带来困难。
通风与空调系统的风管设计工作压力为1000Pa。项目部决定风管及部件在场外加工。
项目部制订的施工进度计划中,施工高峰期在6月至8月,正值高温季节。根据地下室的气候条件和比赛大厅高空作业多的特点,需制订针对性施工技术措施,编制质检计划和重点部位的质量预控方案等,使工程施工顺利进行,确保工程质量。
在施工过程中,由于个别班组抢工期,在管理上出现工序质量失控,致使在试车阶段发生施工质量问题,如通风与空调系统进行单机和联动试车时,有2台风机出现震动大、噪声大、电动机端部发热等异常现象。经调查发现:风机的钢垫铁有移位和松动;电动机与风机的联轴器同轴度超差。

问题


变配电装置进入调试阶段,因环境湿度大,会造成调试时测试不准或不能做试验,在管理上应采取哪些措施
