【背景资料】
A 安装公司承包某大楼的建筑电气工程施工。工程内容有地下变电所、配电干线、室内配线、照明系统。合同约定：主要设备（三相电力变压器、成套配电柜）由业主采购，其他设备及材料由A 安装公司采购。大楼的一次结构已完工，大楼的二次结构、装饰工程由 B建筑公司承包施工。
A 安装公司项目部进场后，依据 B 建筑公司提供的二次结构、装饰工程的施工进度计划等资料，编制了建筑电气工程的施工方案、施工进度计划（见下表）。在施工方案中合理安排了变压器、成套配电柜、插接式母线槽的施工程序。在制订施工进度计划时，要求设备材料采购与施工进度合理搭接。

在工程施工中，曾经发生过2 个事件：
事件1：在插接式母线槽的施工中，因碰到雨季，空气潮湿，母线槽安装后检查，绝缘不合格，不能送电，影响了送电时间，经返工，到7 月 1 日才送电完成。
事件2：在照明通电调试时，有个别Ⅰ类照明灯具外壳带电，经检查，在 2.4m 以上灯具外壳没有接地，灯具相线接错，造成灯具外壳带电，重新整改后，照明灯具通过验收。A 安装公司积极与 B 建筑公司协调，使电气工程的施工符合装饰工程的施工进度计划，A 安装公司和 B 建筑公司共同实施对大楼的建筑装饰、电气工程等工程的竣工验收，使机电工程按合同要求完工。

背景：某施工单位总承包一矿井建设工程，该矿井采用立井开拓，主、副、风井三个井筒均在同一工业广场内，均采用冻结法施工。主井井筒净直径6.0m，井深720m；副井井筒直径7.0m，井深695m；风井井筒净直径5.0m，井深690m。矿井属于高瓦斯矿，且井下巷道较多，开拓任务重，工期紧。矿井开工前，建设单位提交了矿井的地质报告、井筒检查孔地质柱状图、地面工业广场布置图、修建了进矿道路及供电线路等。该施工单位依据上述条件编制了矿井的施工组织设计，其主要内容如下：
（1）矿井开工前完成供水、供电、运输、通信以及工业工程平垫的前期工作，主要污水排放管道的敷设工作。
（2）由于矿井无边界风井，确定矿井采用单向掘进施工方案。副井井筒利用永久井架凿井，井筒的开工顺序依次为中央风井、副井、主井，主井箕斗装载硐室与主井井筒同时施工，井筒到底后进行主井与风井的贯通，进行主井临时改绞，再与副井贯通，同时开展井底车场巷道及大巷的施工。
（3）考虑到井下巷道较多，开拓任务重，工期紧，因此井下大巷均采用成熟的机械化配套作业线，煤巷采用综掘机掘进。岩石巷道综合月进尺按100m，煤巷月度综合进尺按300m配备，井下采用固定箱式矿车有轨运输。
（4）井筒到底后，井筒装备交替方案是主井临时改绞，风井进行永久装备，副井也进行永久装备，副井交付使用后进行主井的永久装备。
（5）在风井井筒永久装备完成后，进行采区巷道的施工，同时进行井下生产系统安装和试生产。
（6）矿井建设的施工组织由该公司负责，劳动力统一调配，冻结工程经建设单位同意后分别分包给了三家冻结公司。

Copying Birds May Save Aircraft Fuel

Both Boeing and Airbus have trumpeted the efficiency of their newest aircraft, the 787 and A350 respectively. Their clever designs and lightweight composites certainly make a difference. But a group of researchers at Stanford University, led by Ilan Kroo, has suggested that airlines could take a more naturalistic approach to cutting jet-fuel use, and it would not require them to buy new aircraft.

The answer, says Dr Kroo, lies with birds. Since 1914, scientists have known that birds flying in formation—a V-shape—expend less energy. The air flowing over a bird’s wings curls upwards behind the wingtips, a phenomenon known as upwash. Other birds flying in the upwash experience reduced drag, and spend less energy propelling themselves. Peter Lissaman, an aeronautics expert who was formerly at Caltech and the University of Southern California, has suggested that a formation of 25 birds might enjoy a range increase of 71%.

When applied to aircraft, the principles are not substantially different. Dr Kroo and his team modeled what would happen if three passenger jets departing from Los Angeles, San Francisco and Las Vegas were to assemble over Utah, assume an inverted V-formation, occasionally change places so all could have a turn in the most favourable positions, and proceed to London. They found that the aircraft consumed as much as 15% less fuel (coupled with a reduction in carbon-dioxide output). Nitrogen-oxide emissions during the cruising portions of the flight fell by around a quarter.

There are, of course, knots to be worked out. One consideration is safety, or at least the perception of it. Would passengers feel comfortable travelling in companion? Dr Kroo points out that the aircraft could be separated by several nautical miles, and would not be in the intimate groupings favoured by display teams like the Red Arrows. A passenger peering out of the window might not even see the other planes. Whether the separation distances involved would satisfy airtraffic-control regulations is another matter, although a working group at the International Civil Aviation Organisation has included the possibility of formation flying in a blueprint for new operational guidelines.

It remains to be seen how weather conditions affect the air flows that make formation flight more efficient. In zones of increased turbulence, the planes’ wakes will decay more quickly and the effect will diminish. Dr Kroo says this is one of the areas his team will investigate further. It might also be hard for airlines to coordinate the departure times and destinations of passenger aircraft in a way that would allow them to gain from formation flight. Cargo aircraft, in contrast, might be easier to reschedule, as might routine military flight.

As it happens, America’s armed forces are on the case already. Earlier this year the country’s Defence Advanced Research Projects Agency announced plans to pay Boeing to investigate formation flight, though the programme has yet to begin. There are reports that some military aircraft flew in formation when they were low on fuel during the Second World War, but Dr Lissaman says they are unsubstantiated. “My father was an RAF pilot and my cousin the skipper of a Lancaster lost over Berlin,” he adds. So he should know.
