通常情况下,我们中国人喜欢在上司或者是老板安排任务的时候,会讲好的,没问题。这,表现得自己很有能力,而且希望自己不要给老板留下坏印象。但是,实际上,当我们接了某一个CASE后,发现自己其实是做不了的。于是,烦心不说,最后还惹来不必要的麻烦。
在美国也要注意这方面的事情,而在美国,许多人接下这个活,其实并不是说他没有能力做。而实际上是许多美国新人接下活后,就不去做这件事。等到老板问起来的时候,才发现自己没有做。这样,会让对方感觉你是一个不可靠的人。所以,以后他们也不... 阅读全帖 |

外媒指中国最新“清”级潜艇已下水 性能非常好
时间:2012-07-13 08:54:57 来源:南海网 作者:郭懿芝
环球网资料图:中国海军最新型常规动力潜艇。
虽然说中国094型核潜艇因为“巨浪”-2潜射弹道导弹发展不太顺利而迟迟未能正式部署
,但中国现代化的常规动力潜艇研制的速度却非常快,而且性能非常好。
俄罗斯《国防》杂志近日刊登文章称,中国从去年开始试验043型“清”级新型柴电潜艇
的首艇,同时还在建造另外两艘“清”级潜艇,其中一艘已在今年1月份下水。
有消息称,巴基斯坦方面已经提出采购数艘“清”级潜艇,而且该潜艇将搭载“长剑”
-10K巡航导弹。这种巡航导弹的射程超过1500公里,巴基斯坦购买这批潜艇的目的很明
显,就是要与印度海军的核潜艇形成对抗,以保持互相威慑的态势。
中国“清”级潜艇“非常先进”
根据西方掌握的资料,中国AIP动力装置是某研究所从1996年开始研制的,该所专家掌握
了瑞典公司斯特林发动机的技术,在国产潜艇新型动力装置研究方面取得了长足进展... 阅读全帖 |

n********d 发帖数: 7676 | 22 量子通信之不负责任科普
首先,量子通信分广义和狭义。广义是用纠缠态光子来做信息载体,就好像无线通信通
过无线波传信息,光通信通过光(一般是激光)传信息。广义量子通信有很玄的部分,
比如teleportation,就是说纠缠光子在无限远距离可以传送状态,近似于心灵感应。
这个理论上靠不靠谱咱不说,咱不搞物理,但是这个离实际应用似乎还有若干光年的距
离,所以这里咱不拿这个说事。好吧,如果你是物理专家,觉得这个很靠谱,很快就能
用来传hello world。那就不用往下看了。
那么不谈这个teleportation,就说说单光子的的传送吧。这个和心灵感应不同,是需
要发送光子到接收端的。这个大家都能接受,对吧?现在的量子通信是怎么做的呢?光
子是波啊,有波就有振动方向啊。这个方向在传输过程中如果不受干扰是不变的。物理
名词叫偏振态。接收端用一个偏振镜,你就想象成一个细缝吧。那么这个细缝的方向和
这个波的偏振方向是一致的话,这个光子就可以被接收到了。接收端的偏振片是要转动
的,转一个角度收一个光子。很简单吧。别被纠缠态啥的名词忽悠了,激光通信里偏振
态是一个研究很多的问题,不同偏振态的光子在介... 阅读全帖 |

i****x 发帖数: 17565 | 26 这几天,大众汽车的高层都在被美国环保署(EPA)下令召回近50万辆汽车的事搅得心
神不宁。其因是从2008年-2015年间售出的共计48.2万辆柴油车涉事排放造假,或将面
临最高180亿美元的罚单。然而这整件事并非如我们想象是EPA调查并且发现的。据彭博
社最新消息,是一位名为Peter Mock的行业人士在实验中找出的端倪。
Peter Mock是一个不知名清洁空气组织的欧洲常务董事,他去年在欧洲对帕萨特、捷达
和宝马X5等15款柴油车进行了道路排放测试,并发布了一份名为《主流柴油车型在实际
道路中的排放测试》(REAL-WORLD EXHAUST EMISSIONS FROM MODERN DIESEL CARS)的
报告。其初衷是为了测试这些主流的柴油车是否能符合最新的欧6标准。
实验中他发现,大众的柴油动力车在行驶中会喷射有害废气,且超标。于是他又萌生了
新的想法,他希望在美国做一遍同样的实验。他认为,在美国这个全球排放法规最严苛
的国家,美版车型应该能满足法规要求。然而,当Mock和他在ICCT(国际清洁交通委员
会)的小伙伴John German进行实验时,发现结果和他们的... 阅读全帖 |
