某既有人防工程地下室,战时的隔绝防护时间经校核计算不满足规范规定值,故战时必须采取有效的延长隔绝防护时间的技术措施,下列哪几项措施是正确的

A.设置氧气再生装置、高压氧气罐

B.尽量减少战时掩蔽人数

C.尽量较少室内人员活动数、严禁吸烟

D.加强工程的气密性

答案

参考答案:A,B,C

解析: 根据《人民防空地下室设计规范》GB 50038—2005第5.2.5条,当计算出的隔绝通风防护时间不满足规定时,应采取生O2、吸收CO2或减少掩蔽人数的等措施及计算公式看,BC两项肯定是正确的。选项A是错误的,根据《人民防空地下室设计规范》GB 50038—2005第5.2.5条,当隔绝防护时间不能满足要求时,“应采取生O2、吸收CO2或减少掩蔽人数的等措施”,前一项措施“设置氧气再生装置”无错;根据《人民防空工程设计防火规范》GB 50098—2009第3.1.6条,供平时作为商场使用的防空地下室,“不应经营和储存火灾危险性为甲、乙类储存物品属性的商品”,氧气是助燃气体,在《建规》第3.1.3条中定义为火灾危险性乙类储存物品,由此推断后一项措施“设置高压氧气罐”错误;因此,此条错误。选项D是错误的,“加强工程的气密性”无助于获取O2和排除CO2

单项选择题

The European Union’s Barcelona summit, which ended on March 16th, was played out against the usual backdrop of noisy "anti-globalization" demonstrations and massive security. If nothing else, the demonstrations illustrated that economic liberalization in Europe--the meeting’s main topic--presents genuine political difficulties. Influential sections of public opinion continue to oppose anything that they imagine threatens "social Europe", the ideal of a cradle-to-grave welfare state.

In this climate of public opinion, it is not surprising that the outcome in Barcelona was modest. The totemic issue was opening up Europe’s energy markets. The French government has fought hard to preserve a protected market at home for its state-owned national champion, Electricite de France (EDF). At Barcelona it made a well-flagged tactical retreat. The summiteers concluded that from 2004 industrial users across Europe would be able to choose from competing energy suppliers, which should account for "at least" 60% of the market.

Since Europe’s energy market is worth 350 billion ( $ 309 billion) a year and affects just about every business, this is a breakthrough. But even the energy deal has disappointing aspects. Confining competition to business users makes it harder to show that economic liberalization is the friend rather than the foe of the ordinary person. It also allows EDF to keep its monopoly in the most profitable chunk of the French market.

In other areas, especially to do with Europe’s tough labor markets, the EU is actually going backwards. The summiteers declared that "disincentives against taking up jobs" should be removed; 20m jobs should be created within the EU by 2010. But only three days after a Barcelona jamboree, the European Commission endorsed a new law that would give all temporary-agency workers the same rights as full-timers within six weeks of getting their feet under the desk. Six out of 20 commissioners did, unusually, vote against the measure--a blatant piece of re-regulation--but the social affairs commissioner, Anna Diamantopoulou, was unrepentant, indeed triumphant. A dissatisfied liberaliser in the commission called the directive "an absolute disaster".

The summit’s other achievements are still more fragile. Europe’s leaders promised to increase spending on "research and development" from its current figure of 1.9% of GDP a year to 3%. But how will European politicians compel businesses to invest more in research Nobody seems to know. And the one big research project agreed on at Barcelona, the Galileo satellite-positioning system, which is supposed to cost 3.2 billion of public money, is of dubious commercial value, since the Europeans already enjoy free access to the Americans’ GPA system. Edward Bannerman, head of economics at the Centre for European Reform, a Blairite think-tank, calls Galileo "the common agricultural policy in space.\

What is the passage mainly about()

A. A review of EU’s Barcelona summit

B. About merits of a EU’s summit

C. A survey of Europe’s competitors

D. About the achievements of the EU
