美国国务卿喜莱莉因肠胃炎外加脑震盪挂病号,引发阴谋论,美国驻联合国前大使
波顿表示,喜莱莉得的是「外交诈病(diplomatic illness)」,因为她不想出席20日
的利比亚班加西使馆攻击事件国会听证会;国务院发言人卢岚18日驳斥波顿的说法,对
这样的质疑表示遗憾。
美驻班加西领事馆攻击血案的独立调查小组已公布报告,严厉批评国务院对于驻外
使馆保护不周。喜莱莉表示接受批评并指示国务院执行一连串改革,加强外馆维安。
喜莱莉的健康问题引发关注,更让华府政坛有兴趣的则是新任国务卿人选。包括华

美国国家点火装置的工程师正在检查核聚变反应炉。
国家点火装置(NIF)接近能量临界点,一旦成功,世界能源结构将被改写。但目前
,NIF仍然面临一系列不确定性。

或许在今年,美国国家点火装置(National Ignition Facility,NIF)将变得名副

新浪科技讯 北京时间11月14日上午消息,美国科技博客BusinessInsider CEO亨利·布
洛吉特(Henry Blodget)周三在Ignition 2013科技大会上透露,谷歌(1035.23, 2.76,
0.27%)的广告营收已经超过了全美所有报纸或杂志的广告营收总和。
谷歌的规模之大已经无可置疑,但除了600亿美元的年收入外,很难直观地了解该
公司的规模具体有多大。但根据这一对比,便可以很容易想象出该公司的规模。
之所以出现这一情况,一方面源于印刷媒体的广告收入大幅下滑,但值得注意的是
,谷歌2012年的营收就已经接近美国杂志行业在2007年创造的历史最高广告营收。
也就是说,要不了多久,谷歌的年营收不仅会超过美国杂志行业目前的年度广告营
收,还会超越这一数字的历史最高值。(书聿) |

空耳在流行用语为故意将一种语言以另一种语言的谐音重写内容,以达到恶搞或一语双

实现氢硼聚变。
以氘氚为材料的核聚变反应将产生大量中子,当这些中子冲击核反应堆壁时,会产生

成的放射性核废料要清洁得多,但从长远角度来看,探索新的、更干净核燃料非常有必

聚变过程中,如果产生的中子能不超过总输出能量的1%,相应的聚变被称为无中子聚
