阿城区儿童医院预约免费Afterglow 夕照,晚霞Heres an experiment you can try: look at something bright relative to its surroundings, such as a lamp or a sunny window, for ten seconds without blinking. Then shut your eyes and cover them over with your hands.你可以尝试这样的试验:不眨眼盯着看相对周围而言光亮的东西十秒钟,比如,一盏灯或洒满阳光的窗户;接着闭上眼睛且双手蒙住。You will find that the lamp or window still seem to be hovering in front of you, quite visible at first and only gradually fading away. Yet your eyes are closed and your hands are blocking them completely — so where is the light coming from?你会发现那盏灯或窗户依旧浮现在眼前,最开始清晰得很,又慢慢消失。可是,你不是闭眼了吗?况且双手不是严实地蒙住了吗?那么,光线从何而来?The answer is that the afterglow light you see isnt really light at all. Its the result of residual activity of the nerve cells on the back of your eye, called the retina. In sensory psychology this effect is called a ;positive afterimage;.是残留的余光根本不是真正的光芒。其实这是视网膜(眼后的神经细胞)的痕迹作用。感官心理学将这种现象称作“正后像”。You can think of it as something like the vibration of a string after it has been struck. The players finger is taken away, and yet the sound continues, because the energy she or he put into the string takes a little while to dissipate.你可以将“正后像”视为拨动后琴弦的振动。弹琴者手指离开了琴,而琴音依旧。因为琴弦上的能量需要点时间消退。Its a similar situation with your eyes. In order to respond usefully to such a relatively faint signal as light, the cells in the retina need to be very sensitive. Over-stimulate them and some will continue responding for a couple of seconds after the stimulus is removed.视觉的情况也类似,视网膜细胞的感光十分敏感以便及时感知像光线般微弱的信号。受到过度刺激的视网膜细胞,部分在刺激后持续反应。Of course, the only thing we ever ;see;, really, is the activation of our retinal cells — thats what our brains interpret as light from the outside world. So for as long as it takes for them to calm down, you will continue to see a faint glow of light — even though nothing is there.当然,唯一我们“看到”的是视网膜细胞的激活也就是大脑解读的:外界的光线。所以,只要刺激后需要时间平复,你就能持续看到微弱的灯光,虽然,实际上并不存在。 /201210/206663哈尔滨市医大三院网络咨询 Dear Annie:亲爱的安妮:I have a wonderful friend who has become a complete cell phone addict. Last week I gave her a ride to the airport, which I was absolutely happy to do, but it was clearly a favor. All the way there, she ignored me and yakked on her cell phone to her grown children.我有一个很好的朋友,现在已经完全成了一个手机控。上周我开车搭她到机场,我绝对很乐意那样做的。我显然是在帮她的忙。但是整整一路,她都把我当空气,在她的手机里和她已经长大的孩子喋喋不休。I was insulted, but figured if I complained, I would appear jealous of her relationship with her kids, of which she is quite proud. Did I make the right choice? Dont cell phone addicts realize they make the people they are with feel like a dime waiting on a dollar? What can I do? - Cell Free我被冒犯了,但我不知道是不是心存抱怨,是否会显露出对她和她孩子之间的关系的嫉妒之情;;她颇为自豪的就是她和孩子的良好关系。我该怎么做?难道手机控们没有意识到,他们的行为让和他们在一起的人感到备受冷落吗?我该怎么做? ;;;一个无手机的人;Dear Cell Free:亲爱的;无手机的人;:People who are overly attached to their phones do not realize how rude they are, and in this instance, your friend may have been showing off a bit. You can tell her that it bothers you to be deliberately ignored and hope she will shape up. Or, you can simply stop whatever you are doing and pointedly but politely wait for her to finish her conversation. If that means parking the car, do it.过于注重自己手机的人没有意识到他们的行为是多么地粗鲁。在这种情况下,你的朋友可能是想稍稍炫耀一下。你可以告诉她,你被故意冷落了,你希望她收敛一点。你可以停下手中的活儿,然后严肃但礼貌地等待她打完电话。如果需要停车的话,那就停吧。201203/175230齐齐哈尔市第一医院治疗不能怀孕

巴彦县妇幼保健医院四维彩超预约 NOT long ago, Barack Obama was hoping that high-speed trains would provide America with the desired ;twofer;. First, building the special tracks and locomotives would put a division or two of Americarsquo;s army of unemployed back to work. Then, once built, the trains would get people out of cars and planes and to their destinations in a way that would be cleaner and use less foreign oil. But those dreams have mostly died. Republicans have decided that government spending, not outdated infrastructure, is the real bogeyman, and Republican governors in Florida, Wisconsin and Ohio have rejected federal money to begin building.前不久,奥巴马希望通过高铁的修建给美国带来梦寐以求的两项实惠。第一,高铁轨道的修建及机车的制造将会让美国的无业人员重获工作。并且,一旦完工,人们的出行方式将从汽车和飞机变成高铁,一种更加清洁环保并且可以减少使用国外石油的出行方式。但这些美好的愿望几乎已全部幻灭。共和党人决定政府的开不应花在过时的基础设施建设上,这是建造高铁的困难所在,在弗罗里达,威斯康星和俄亥俄州的共和党州长已经拒绝了用联邦州政府的公债基金建设高铁。Only in California does the dream live on. As Governor Jerry Brown, aged 73 and a Democrat, likes to remember, another big railway project in the 19th century connected the young state to the rest of America. In the 1960s his father, Pat, served as governor and built ambitious aqueducts and highways. In the 1970s Mr Brown himself became governor for the first time, and had visions of his own grand projects. These, as much as his theological bent and his liking for meditation, earned him the nickname ;Governor Moonbeam;.唯有在加州建造高铁的愿望尚存一丝希望。因为73岁的民主党州长Governor Jerry Brown喜欢回忆19世纪另一项宏伟的铁路工程,该工程使成立不久的加州与美国的其它地区相连通。20世纪60年代,Brown的父亲Pat担任州长时建造了宏伟的水道和高速公路,70年代 Brown首次当选州长,并勾画建造自己宏伟工程的蓝图。以上这些加之他对神学的虔诚及酷爱冥想, 因此人们称之为;月光州长;。Today Mr Brown still sparkles as he mocks the ;dystopian journalists; and ;declinists; who obstinately fail to see that Californiarsquo;s population will grow from just under 38m now to about 50m in 2030; and that, unless the state has something like Japanrsquo;s bullet trains, Californians will choke in traffic jams or go mad waiting for delayed flights in inadequate airports. Of late, he has compared his statersquo;s planned high-speed train to the Panama and Suez canals. And he has added that if China, Germany, Spain and Japan can build one, there is no earthly reason why California shouldnrsquo;t do so too.现今Brown因嘲弄;反乌托邦记者;和;下滑主义者;仍耀眼于政坛,;下滑主义者;顽固的认为加州现今不足3800万的人口在2030年将无法达到5000万;并且,加州除非有像日本的新干线之类的新型出行方式,否则加州市民在机场为数不多的情况下,不在交通拥堵中窒息就在因航班延误造成的慢长等待中疯狂。最近,Brown把修建高铁的计划比作同修建巴拿马及苏伊士运河一样重要势在必行。他补充道,如果中国,德国,西班牙和日本都可以建造高铁,那么还有什么理由能阻止加州也来建造高铁呢。Californiarsquo;s voters used to agree. In a 2008 ballot measure (before Mr Brown became governor for the second time), they approved billion in bonds to fund just such a train. As advertised, it was to connect the two big population centres, Los Angeles and the San Francisco Bay area. Speeds were to reach 220mph, giving a travel time of less than three hours; the project was to cost billion and be completed as early as 2020.加州的选民之前对此表示持。在2008年的投票表决中(Brown第二次任州长前),选民同意拿出90亿美元债券基金来建造高铁。如宣传中所描述的那样,该铁路建成后将连接洛杉矶和旧金山海岸地区这两大人口聚集区。到时列车的行驶速度将达到220英里/小时,两地的旅程时间将不到3小时。这项工程将花费330亿美元并预计最早于2020年完工。Then the iron law of infrastructure projects asserted itself. According to current estimates, the train would in fact cost three times as much or more, and take 13 years longer to build. Mr Obama still wants to help; he has asked Congress for billion in railway funding over five years, of which .5 billion may go to California. But even with the bond funds, those dollops would cover less than 13% of the estimated cost. Republicans are in no mood to allocate more.之后基建工程的魔咒又开始应验。根据目前的估计,这项工程实际出费用将是预想的三倍或更多,并需耗时长达13年之久。奥巴马对此仍不放弃并给予一定援助;在过去的五年里他已向国会申请了350亿美元用于铁路建设,其中大约35亿美元用于加州。但即便如此,所有这些费用仍不足预计出的13%。对此共和党人再无心援助更多。It gets worse. After the ballot measure, it was decided that construction should begin not in the two population centres but in the vast and flat farmlands of the Central Valley, where building is much easier. This means that funds could run dry before the big cities are even connected to the network. A high-speed train would then run through sparsely populated countryside, with hardly anybody riding it. Some call this a ;train to nowhere;, others a white elephant. Using a rather more original metaphor Richard White, a professor of history at Stanford, calls it ;a Vietnam of transportation: easy to begin and difficult and expensive to stop.;更糟糕的是,在投票表决后,政府决定将铁路的起止点改建在中央大峡谷的耕地上,而非原定的两个人口密集区,与之前相比这里幅员辽阔,地势平坦易于施工。这意味着在铁路网与大城市连通前,资金很可能早已用光。那时高铁将穿梭于人迹稀少的乡村地区,当然也基本不会有人乘坐。一些人把它叫做;无所适从的列车;,其它人则说它是华而不实,赘而无用。斯坦福大学历史学教授Richard White用隐喻的方法称其为;越南式交通:开始,容易且简单;停止,昂贵且困难;201203/174024哈尔滨医科大学附属第一医院妇产科医院黑龙江省第二人民医院门诊怎么样
