In Level 3, ETCS goes beyond the pure train protection functionality with
the implementation of full radio-based train spacing. Fixed track-release
signalling devices (GFM) are no longer required. As in ETCS Level 2, trains
find their position themselves by means of positioning beacons and via
sensors (axle transducers, accelerometer and radar) and must also be capable
of determining train integrity on-board to the very highest degree of
reliability. By transmitting the positioning signal to the... 阅读全帖

众议院情报委员会主席罗杰斯(左)与众议员Dutch Ruppersberger。

国电信业巨头华为技术有限公司(Huawei Technologies Co.)周一对一份尖锐的美国国

陸證實 測試極音速導彈載具
【中央社╱北京15日綜合外電報導】
2014.01.15 11:39 pm
中國大陸國防部今天表示,大陸1種極音速導彈投射載具已進行試飛,而試飛屬科學性
質,並不針對任何國家。
大陸軍力擴建已引起區域緊張,許多亞洲國家歡迎美國所稱、將較大注意力和軍備再次
轉移到亞洲的計畫。這些國家紛紛增加軍事支出,並加強對美關係。
大陸國防部在傳真給路透社的答覆中說:「在我們領土上進行我們計畫中的科研試驗很
正常,這些試驗並不針對任何國家和任何特定目標。」
這項聲明證實了網路報「華盛頓自由燈塔」(TheWashington Free Beacon)的報導,
指根據偵測,這個極音速滑翔載具(HGV)上週在大陸上空以10倍音速的速度飛行。
美國國防部發言人告訴自由燈塔,部內知道有這項試飛行動。美方將這種載具命名為「
WU─14」。
自由燈塔報導,此次試飛使大陸僅次於美國,成為世上第二個測試極音速投射載具成功
的政權。這種載具將裝置在大陸洲際彈道導彈上,可投射核子彈頭,速度為10馬赫,即

马航MH370客机失联至今已第12天。据马来西亚“南洋网”3月20日报道,能正常运作30
天的飞机黑匣子,其电池寿命现今只剩下18天。若在这剩下期限内,仍没有客机的消息
,将打击搜寻的机会,因为它不能再自动发出任何信号。
据美国广播公司(ABC)报道,“黑匣子”只能耐30天,电池寿命已过了三分之一时
间。
报道说,如果能在电池寿命完全消耗前寻到“黑匣子”,可简易搜索队伍的工作,
因为搜索范围锁定60万平方公里。
据报道,若客机坠海,黑匣子内折“失事定位信标”(beacon)会发出不能靠耳朵听
到的超音波,但却可通过仪器侦察到的信号。
“失事定位信标”旁的感应器一碰触到水,就会自动启动,然后将会发送37.5千赫
(KHz)的频率,发送频率的范围深达4267米。
ABC报道称,一旦“失事定位信标”发出”频”信号,它将会持续30天,每秒发出
信号。搜索队伍必须要在“失事定位信标”的25公里内寻求黑匣子。地形情况也会影响
到“失事定位信标”的信号。

人早说了,这个beacon是uni-directional, 水衰减很少,主要是1/r^2,你说美军要跑
多远才能”听到信号有弱变强有强变弱“?
专家们在开会,弱智你能不能少说几句啊?

没文化就是可怕
天线需要一定的尺寸来满足发射效率,比如,简单振子天线长度需要是波长的一半
声波也一样,声波换能器需要达到一定的尺寸,因为beacon尺寸有限制,不能做太大,
37.5khz大致是传播距离最远的波段.换能器尺寸只需要厘米级,所以是最佳选择,

你这个业内人生大概是业内扫地的吧?

来自主题: Military版 - 冯溪乔: 我和我的美国女友
注:冯溪乔,北大毕业,CUSPEA一期,哈佛博士,UCLA物理系终身教授,1996年为情所
困,在巴黎跳楼身亡。此文为冯溪乔生前所写。
我和我的美国女友
冯溪乔
我中学还没毕业就上大学,大学还没毕业就上研究生院,研究生院结束以后人家马上给
我一个工作,做助理教授的时候才26岁,现在34岁,马上就拿正教授了。事业上可以说
几乎是一帆风顺,但生活中的挫折可就多了。
我大学时有一个女朋友,是北大物理系同学,1980年一块儿考出国,因为她不懂物理,
得靠我帮才行。当时我20岁,她才19岁,两人都考上了。一听去美国,又是有名的学校
,克雷尔、哈佛,从地图上看两个城市近的不得了,所以心理感觉极好。她先到那儿,
在补习班学英文。我一到美国就去42街的旅馆大楼,一看到处亮着灯,非常激动。那里
有一个Finger Lake “手指湖”, 她带我到处跑来跑去,玩得很开心。
然后我就自己去哈佛。在当时我们仅有500多美元,国家给的,两个箱子,所以转脑子
找便宜的办法。当时有学生找学生搭脚的,就是学校专门有这么一个地方,你想第二天
去哪儿,找车搭车,写一个小条放在里面;谁想给车让别人搭,也可以写条放在那里,

Russian nuclear bombers were spotted flying near Alaska this week. The
bombers were escorted by fighter jets, floating just outside of U.S. and
Canadian airspace. This is the second such sighting since June, sparking the
attention of American military jets.
Major Beth Smith, of the U.S. Northern Command and the North American
Aerospace Defense Command (NORAD), has said "Over the past week, NORAD has
visually identified Russian aircraft operating in and around the U.S. air

The National Institutes of Health (NIH) has spent more than $39 million on
obese lesbians, origami condoms, texting drunks, and dozens of other
projects that could have been scrapped in favor of developing an Ebola
vaccine.
“Frankly, if we had not gone through our 10-year slide in research support,
we probably would have had a vaccine in time for this that would’ve gone
through clinical trials and would have been ready,” said NIH Director
Francis Collins, blaming budget cuts for his agency’s fai... 阅读全帖
