青岛去眼袋多少费用Sauroposeidon towers over Deinonychus. In fact, its mammoth size is its primary defense. But this giant begins life very small. 波塞东龙比恐爪龙高出很多。事实上,他们高达的体型就是他们最主要的防御武器。但是这种大型恐龙刚出生的体型很小。For Deinonychus, Sauroposeiden would be a great meal, at least the juveniles, because there would’ve been lots of them and because they would’ve been effectively defenseless. 对于恐爪龙来说,波塞东龙可能是一顿大餐,至少年幼的波塞东龙绝对是一顿大餐,因为年幼的波塞东龙数量很多,而且他们基本上没有什么防御力。When Sauroposeidon reaches full size at around 25 years old, nothing can compete. But this Goliath starts out about the size of a house cat. When these eggs hatch, the young grow fast, but not fast enough. They won’t even reach a ton in weight for at least three years, giving the raptor Dinosaurs plenty of time to attack. 当波塞东龙在出生的25后,生长到最大体型时,没有任何恐龙的防御力能和它们媲美。但是这种“巨人”最开始的体型就和家猫差不多大。当它们的蛋孵化后,幼崽的生长速度很快,但是还不够快到能逃避被捕食的命运。至少3年内,它们的体重都不会超过1吨,这给了迅猛龙扑杀它们的机会。There’s good evidence that Deinonychus killed animals that weighed 10 times as much as it. 一些发现可以很充分明,恐爪龙可以捕杀比他们体型大10倍的恐龙。And 10 times Deinonychus’ weight in raw meat is a very big meal. 而10倍于恐爪龙体型的恐龙绝对可以称得上是大餐了。They could probably feast for a while on, say, a three-year-old Sauroposeidon, an animal the size of a hippo.他们可能会尽情享受一只三岁大的波塞东龙作为食物,而三岁大的波塞东龙体型相当于一头河马。Bringing down an animal 10 times your size takes more than just brains. It requires highly advanced senses. 放倒一只体型大于你10倍的动物,需要的不仅仅是大脑。还需要高度发达的感觉系统。We can tell that it had a good sense of vision, good hearing, and a pretty good sense of smell.我们可以判断,恐爪龙的视觉,听觉以及嗅觉都十分灵敏。In fact, like few carnivores of its day, Deinonychus has a sense of smell so acute, it can track prey in the dead of night. 事实上,和当今的大多数肉食动物不同,恐爪龙的嗅觉极度灵敏,它可以在夜间捕捉到猎物的气味。Inside the snout are two nasal passages. Like an air filter, sheets of sensory tissue are folded to maximize surface area. This tissue contains millions of chemoreceptors, nerves that capture odor molecules. So Deinonychus can sniff out prey from miles away. 它们的鼻子里面有两条鼻腔。就像是空气过滤器,多层的感官组织折叠在一起以便最大面积接收信息。这个器官包含数百万个化学感受器,以及可以捕获气味分子运动的神经。因此,恐爪龙可以闻到几英里外的猎物的气味。The sense of smell in Deinonychus could alert…恐爪龙的嗅觉系统可以警戒...英文文本来自普特英语,译文属未经许可不得转载。201403/279816青岛泰安假体隆胸医院 The signs are unmistakable: the eyes water, the chest heaves, the nose twitches, the body tenses, suspense builds... until finally a sneeze blasts forth, concluding the drama.眼睛湿润,胸部隆起,鼻子一阵抽搐,身体紧绷,就这样待定着,到最后一个喷嚏响起,像是演了一出戏剧!Its a momentarily paralyzing experience that can seize one at almost any time.这使得人的身体短暂麻痹,它几乎可以在任何时间让一个人给紧缩。But try and recall if youve ever been jarred out of a peaceful sleep by an explosive sneeze.但是,试想你曾经有过在安详的睡眠中被一个突然的喷嚏给震醒的情况吗?Chances are you cant, because, thankfully, we dont sneeze while we sleep.你是不会有的,因为很庆幸,我们在睡觉的时候不会打喷嚏。To understand why, first we need to know why we sneeze while were awake.要理解其原因,我们首先需要了解为什么我们会在醒的时候打喷嚏。Sneezing is a reflex, which means that its an uncontrollable physical response to an outside stimulus.打喷嚏是一种反射,也就是说它是一种生理对外界环境的反应,不可控制。When something, say a piece of dust or a strong odor, stimulates nerve endings in the lining of the nose, the stimulus travels to the central nervous system and is then routed back to the muscles of the face, throat and chest.有时候,像一颗尘埃或一股强烈的味道刺激了鼻子里的神经末梢,这个刺激就会到达中枢神经系统,继而再返回到脸部、喉咙和胸部的肌肉。Once stimulated, these muscles go to work and cause us to forcefully expel air from the mouth and nose.这些肌肉一旦被刺激,它们就会运动,导致我们强有力的排出口腔和鼻子里面的空气。Or, in other words, we sneeze.或者,换句话说就是打喷嚏。Because the nose lining tends to swell when we lie down, making it even more sensitive to sneeze-causing particles, it would seem that sneezing would be likely during sleep.因为在我们躺下的时候,鼻子里面部分趋于隆起,这使得它对引起打喷嚏的微小颗粒更加敏感。这样看来,似乎在睡觉的时候更容易打喷嚏。However, since there is little airflow in most bedrooms at night, and little movement to stir up dust and other particles, the nose is not bombarded by as many foreign particles as it is during the day.然而,由于我们的卧房里在晚上几乎没有空气流动,也没有什么运动会扬起灰尘及其它微粒,所以就不会有像白天那么多外界微粒来刺激我们的鼻子。Furthermore, the area of the brain responsible for the sneeze reflex relaxes while we sleep.而且,当我们睡觉的时候,脑袋中负责打喷嚏反射的区域也休息了。So, even when a particle does touch the nose lining, the brain doesnt notice, and we dont sneeze. 所以,即使有微尘碰触了鼻子内部,大脑也没意识到,我们就不会打喷嚏。 201401/271451莱芜人民医院开双眼皮多少钱

青岛治疗皮肤暗黄多少钱 Business商业报道A Mexican start-up一个墨西哥式的开始Border buzz边境上的嗡嗡声A small dronemaker is a fine example of cross-border co-operation一个小小的遥控飞行器是跨境合作的一个典型范例。FEW companies embody the spirit of Mexican-American co-operation as much as 3DRobotics, founded by a Mexican, Jordi Muoz, and an American, Chris Anderson.很少有公司像3D机器人公司,由一个墨西哥人和一个美国人建立,一样象征了美国墨西哥裔合作精神。The factory in Tijuana where they make their small drones is so close to the border that they could, if they were allowed, fly across to San Diego.在蒂华纳的工厂,那里他们制作他们小小的遥控飞行器,距离边境非常近以至于它们,如果允许的话,可以飞越边境去圣地亚哥。That is where the firms boffins engineer them.那是他们公司的工程师。Mr Muoz, born a few hours south of Tijuana, grew up dreaming of building robotic flying machines, but only managed to do so after moving to California.Mr Muoz,出生在离蒂华纳南部开车要几个小时的地方,从小梦想着制造一个遥控飞行器,但仅仅在他搬到了加利福尼亚后才实现这个梦想。He says he could not have succeeded without the ed States technological prowess and entrepreneurial culture.他说道如果没有美国的技术实力和创业文化他是不能够成功的。Yet chicanadas—the knack Mexicans reckon they have for using whatever is at hand to solve a problem—were also crucial.但是墨西哥人自己的思维方法—墨西哥人认为他们拥有的利用任何手边的条件来解决问题的做事窍门——也很关键。He began to make progress in 2006, when the imminent launch of Apples iPhone triggered a plunge in the cost of the motion sensors he needed to build his dream.他在2006年开始有进展,当时苹果的iphone即将发行引起了对他需要的构建梦想的动作传感器的经费投入。He found that in America he got plenty of encouragement.他发现在美国他得到了许多的鼓励。Unlike Mexico, it has a culture that lets you believe you can be the best in the world, he says.不像在墨西哥,它有一个让你相信你能够成为世界上最优秀的人的文化,他说道。It is easy to buy supplies on eBay—and, again in contrast to Mexico, the postal system delivers them quickly and reliably.在eBay上很容易买到供应的材料,并且,与墨西哥相反的是,邮政系统交付货物迅速可靠。Mexican bureaucracy makes it hard to get started: even a tiny garage start-up requires an industrial permit.墨西哥的官僚主义让它很难起步:即使是一个小小的车库的运营也需要工业许可。Mr Muoz says most Americans dont trust Mexicans very much;Mr Muoz说大部分美国人并不非常相信墨西哥人;but he credits Mr Andersons untypical background for helping him to see beyond the racial stereotype and write a 500 cheque for Mr Muoz the first time he met him: The best 500 hes ever spent.但是他相信安德森的非典型背景,帮助他打破种族思维定势;并且在安德森第一次见他的时候就开了一张500美元的票给他:他曾经花过的最值的500美元。As for chicanadas, he says his first plastics were moulded in a toaster.至于墨西哥人的诀窍,他说他的第一次作品模型是在面包机理做出来的。Before the firm had its own premises, Mr Muoz got some friends to assemble the drones in their kitchen.在这家公司得到自己许可之前,Mr Muoz和他的朋友聚集在他们的厨房装配无人机。From such humble beginnings, 3DRobotics hopes its pilotless craft will be used for anything from monitoring crops to lifeguard duties on beaches.从如此低的起点开始,3D机器人公司希望它的无人机技术被用来监视任何东西,从沙滩上的人群到救生员职责。Its neither a San Diego firm nor a Tijuana firm, says Mr Muoz. It will always be both.它既不是一个圣地亚哥公司也不是一个蒂华纳公司,Mr Muoz。它总是两者兼有。 /201311/262947青岛打瘦身针青岛连云港哪里祛痣好
