自贡市第四人民医院流鼻血要多少钱石柱土家族自治县看外耳道炎大概多少钱费用Because from trillions of miles away, these small planets get lost in the blinding glare of their starsbrightness.因为从几万亿光年外看,这些小行星会被周围恒星的耀眼光芒所埋没。The sad truth of the matter is that earth-like planets are near cosmic specks of dust.据说类地球的形体好像宇宙中微尘。And therefore detecting them is really quite hard.所以说侦测到它们时间十分困难的事情。Hard, but not impossible. Every now and again, the planet passes directly between us and the star.困难,但并不是没有可能,行星有时会从我们地球和恒星之间穿过。And if it does that, its like a little eclipse. And the star-light drops.当它穿过时就形成了类似蚀的情况,那么恒星的光亮就会减弱变得灰暗。It gets darker because the planet is blocking the light from that star. And it turns out we can see that.因为行星挡住了恒星所发出的光,而结果是我们可以看到那颗行星。With this in mind, scientists built one of the worlds most sensitive telescopes and launched it into space.具备了这种理论,科学家们制造了世界上最敏锐的望远镜之一并发射入太空。The mission called Kepler may not help us find E.T, but it could help us find its home.这项任务叫做开普勒计划,虽然不太可能帮助我们找到外星人,但是可能帮助我们找到他们的家。Kepler will simply do one thing unbelievably well--measure the brightness of 100,000 stars over and over and over,looking for a few of those 100,000 stars that dim.开普勒能将它唯一的一件工作做到极致就是一次又一次地测量几十万星星的光亮度,试图找到其中少数发暗的星体。Seeing the tiniest dim from a small planet travelling in front of a star thousands of light-years away isnt easy to imagine.从几千光年外观测穿过其恒星的小行星发出的暗光是难以想象的。But the Kepler telescope is one of the most sensitive cameras ever built.但开普勒望远镜是世界上最敏锐的照相机。To give you an idea of just how sensitive Kepler is, Im gonna demonstrate using this massive World War II search light.为了让你们知道开普勒到底敏锐到什么程度,我要用这个二战时期的巨大探照灯为你们做演示。The brightness of that search light represents the extreme luminosity of stars.探照灯的光亮代表着恒星极高的亮度。And Im gonna use this tiny marble to represent the planet.而我将用这个小弹珠来代表行星。When this planet passes in front of the star, it blocks out a tiny fraction of the light, dimming the star by a very small amount, and thats exactly what the Kepler space craft can detect.当这个小行星从恒星面前通过时,它会挡住微小的一部分光,使恒星变暗一小小点,而开普勒就能够侦测到这种十分微小的变化。Kepler can detect a 0.01% change in the stars luminosity, but even if it spots a dimming star, theres still another problem.开普勒能够识别恒星万分之一的亮度变化,但即便它检测到一个变暗的恒星,我们还有一个问题需要解决。When Kepler sees a star that dims, it could be due to a speck of dust that crossed in front of the telescope.当开普勒检测到恒星变暗有可能是因为望远镜前的一些尘土。Theres a possibility of binary stars, two stars that orbit each other thereby dimming the stars as one blocks the other.还有可能是双星两个形体相互环绕,就好像是一个挡住了另一个从而使得恒星变暗。 译文属201512/417626重庆市妇保医院过敏性鼻炎治疗的价格 I am so happy to meet you,they showed me this several days ago能见到你太开心了 前几天有人给我看了这个视频And I was like,please,can we have him on the show,can I meet him.我当时就是说 可以请他上节目吗 我可以采访他吗What an inspiring story that is.Okay.So take

speed check,about 3 quarter of the way up the end run to this big jump那次做速度检测 导致了过高的跳跃Its like,I dont know,12 feet tall and 15 feet back from the landing hill大概有三米半高 距离着陆点四米And that wasnt enough speed from where I had assumed would be good,so I went to the very top开始速度不够 没有达到我的预期 所以我从最高点开始滑And felt like I was going a bit fast when I started,but I thought,you know maybe as I got down to the transition and off the jump,Speed would be right而且起步有点儿快了 但我想 到了过渡坡的时候再跳 速度应该刚好But ended up overshooting the landing hill,over-rotating the trick可最终跳得太远了 做技巧翻过头了How high were you about,like?They told me about 10 stories.Ten stories in the air?Ten stories当时跳了有多高 大概十层楼吧 在空中十层楼 十层楼那么高How many stories,I dont know,what youre supposed to be when you do that trick,eight,four stories我不知道几层 正常情况下应该跳多高 八层还是四层楼那么高You should be two or three stories to the landing hill and I just took it way too far 应该是两到三层楼 当时跳得实在太高了and missed the landing hill completely,landing in the flats at the bottom完全飞出了着陆的区域 落到了山底的平地Wow,ok,so you knew when you were in the air,uh,oh right?Thats when you realize是不是在空中的时候你就发觉 啊哦 糟了No,I realize in the transition.It was uh,oh,when I was in the air,It was like oh,no.还在过渡的时候就发现了

攀枝花市中心医院美尼尔怎么样自贡市第四人民医院扁桃体炎看怎么样好不好 How come socks dont lose their power like insoles do? 为什么这种袜子没像鞋垫那样失去效果呢?There are several kinds of odor preventing and odor destroying treatments for textiles. 这是因为袜子织物纤维中有一些防臭和祛臭物质。For the most part, they work by killing or inhibiting the bacteria and fungi that cause odors. 在大多数情况下,它们能够杀死或抑制引起臭味的细菌和真菌。For example, these socks contain Quaternary Ammonium Compounds,or QACs. 比如这些除臭袜子中含有简称QACs的季铵盐化合物。QACs are complex molecules with one end that binds tightly to the surface of the treated fibers. 这种复杂的分子一端能够紧密的吸附纤维表面。The rest of the molecule is made up of a positively charged nitrogen atom and a long chain of carbons. 其余的分子是由带正电荷的氮原子及碳的长链组成。Think of the QAC molecule as an electrically charged sword. 你就把QAC分子想象成一把带电的剑。The long chain of carbons punctures the cell membrane of a microbe, allowing the charged nitrogen to electrically disrupt the cells contents. 其中的碳长链能够刺穿微生物的细胞膜,使带电的氮电子干扰作用细胞本身。Since nothing is bound permanently to the now dead cell, the QAC doesnt lose strength and is y to destroy the next offending microbe that crosses its path.而由于没有永久附着现在已死细胞,QAC并不会失去力量,并且随时做好准备面对下一个冒犯的微生物。201502/359267眉山市中医院打呼噜治疗的价格
