上饶削骨手术医院上饶县妇幼保健人民中医院祛除腋臭多少钱If youve ever been to a rock gig,假如你曾亲临摇滚现场youll probably recognize this screeching noise.大概不会对这样刺耳的噪音感到陌生Its feedback. What causes it is simple.这便是;反馈;,其道理浅显Sound enters the microphone.声音进入麦克风Its transmitted along the wires,随后通过电缆传播make louder by the amplifier.经扩音器放大and comes out at the speakers.最终由音箱发出But if too much of the sound from the speakers go back into the mike,但倘若有太多声音由音箱返回麦克风it goes round and round in a loop,声音便会在此回路中不停折返 getting louder each time.并被逐次放大If no one stops it, feedback can destroy the sound system.如不加阻止,反馈信号将毁坏音响系统I think the same thing will happen with a wormhole,我认为这也同样适用于虫洞only with radiation instead of sound.只不过传播的是辐射而非声音As soon as the wormhole expands, natural虫洞一旦开始张开radiation will enter it and end up in a loop.自然辐射便会进入其中并终结于回路The feedback will become so strong, it destroys the wormhole.反馈将足够强大以至将虫洞摧毁So, although tiny wormhoes do exist,因此尽管微型虫洞的确存在and it may be possible to inflate one someday,而且也可能某天被放大it wont last long enough to be of use as a time machine.其生命之短暂则无法被用作时间机器Thats the real reason no one came to the party.这正是无人光顾派对的真正原因In fact, I believe any kind of time travel to the past through事实上,我基本不相信可以利用虫洞wormholes or any other method is probably impossible.或者其他可能手段重返过去Otherwise, paradoxes would occur.否则便会导致悖论So, sadly,因此遗憾地说it looks like time travel to the past is never going to happen,回到从前似乎永远不会发生A disappointment for dinosaur hunters这对于恐龙猎手恐怕是个遗憾and a relief for historians.但对于历史学界却是种解脱But the storys not over yet.不过故事尚未结束This doesnt make all time travel impossible.这并不意味所有时间旅行都无法实现I do believe in time travel,我对时间旅行深信不疑time travel to the future.相信人们能够跨入未来Time flows like a river,时间如河水般流淌and it seems as if each of us is carried relentlessly along by times current.似乎人类也只能任由时间长河无情地摆布201507/385975鄱阳县妇幼保健人民中医院美容中心 Hi, Im Jessica嗨,我是JessicaAnd today Im going to be talking about chemical demonstration今天我要讲的化学演示I like to call elements on fire叫作着火的元素Lets

slope its a huge amount of wind你可以从痕迹上看出来风很大(整个意思都是说风大,牵涉到未知专门词汇,但不影响理解故简化)these marks here call (a foreign name for this type of mark) tells the story wind pass across雪的表面因此结成了壳it also create a bit of crust从而对你的滑行造成很大阻力just gonna give you a lot more resistance as you coming through the snow the speed is really gonna help a very smooth gradual movements一定的速度可以让你的轨迹更流畅the body position is key, my
