四川省烤瓷牙成都种植牙为什么这么贵Body distance varies from culture to culture. In some cultures, it is quite normal for people to stand close together. While Americans talk about invasion of their space.  身体的接触距离,预示着人与人关系的亲近度,及人和人之间亲近到了什么程度。美国人很注重这种身体上的接触距离,如果站得距离不得当,美国人会认为你侵犯了他们的隐私空间范围。下图揭示了四种距离,这些距离在老美眼里代表什么呢?   1 intimate distance: ranging from direct contact to about 45 cm, which applies to the closest relationships such as husband and wife   2 personal distance: ranging from 45 to 80 cm, which is usually maintained for conversations between friends and relatives  3 social distance: ranging from 1.3 to 2 metres, which covers people who work together or are meeting at social gatherings   4 public distance: which is beyond social distance, such as that kept between a lecturer and his audience  可见,老美把人与人间的距离划归为四类: intimate, personal, social and public。   Body distance varies from culture to culture. 典型的例子就是美国人和阿拉伯人之间的差异。Arabs tend to maintain a closer physical distance between individuals than Americans.   The desert conditions have driven the Arabs into cities where they get used to living in crowds. Because of the high population density, pushing and shoving is unavoidable in public places and people have aly grown accustomed to it. Public is public: no one has the right to demand a private zone around himself as a European or American does . So it is quite natural that people do not have any concept of a private zone outside the body . The emotional closeness of the Arabs means people are deeply involved with each other and do not like to be alone. As for face-to-face communication, the distance between two persons can be so close that both can smell eahand in handch other. This is not something unpleasant, but a way of showing involvement .地理环境潜移默化地影响着阿拉伯国家的文化。 恶劣的生存环境致使大批阿拉伯人涌入城市。习惯了拥挤喧嚣,人与人的亲密无间令他们感到踏实舒心,这一点上阿拉伯文化同欧美文化是截然相反的。  有趣的是, 即便是同一个国家,不同年代的人身体接触的距离也是有差别的。比如英国的年轻人就比老人拥抱朋友的次数多。  许多英语说法都和"arm", "hand" and "finger" 有关,下面就为大家介绍一些。其中有些用法一看就能明白它们的意思,比如 "keep somebody at arm's length" 和 "hand in hand"。然而,有些说法却可能是你想不通的。没关系,我们会告诉你。 /200803/29273广元市第四人民医院超声波洗牙好不好 成都人工种植牙价格多少

Its net profit also headed south, falling to 165 million yuan, down 59.3 percent year-on-year.苹果的玻璃盖板供应商蓝思科技一季度营收下跌了35.8%。至27亿元。该公司净利润也举步维艰,同比大跌59.3%至1亿6500万元。Apple#39;s battery supplier, the Shenzhen-based Desay Corporation, saw its revenue fall 16.6% and its net profit plunged 34.3%.苹果的电池供应商深圳德赛集团营收下滑16.6%,净利润骤减34.3%。Electric motor provider Jinlong Machinery And Electronics Co Ltd, meanwhile, witnessed its net profit retreating 19.8 percent year-on-year to 85 million yuan, according to the company#39;s first-quarter earnings report.电动马达供应商金龙机电股份有限公司的第一季度营收报告也显示,其净利润同比下降百分之19.8至8500万元。As Apple#39;s earnings drop, the US company cut the prices of its major suppliers, with the prices of some components squeezed by as much as 30%.由于收入下滑,苹果对主要供应商进行压价,有些零部件压价甚至达到了30%。Apple#39;s suppliers reacted by continuing a process of diversification, starting to provide components to domestic smartphone makers and tapping into the automobile market.苹果供应商通过保持多元化经营方式进行应对,开始为国内智能手机制造商提供零部件,并进军汽车市场。 /201605/445193高新区拔牙智牙什么价格

阆中市人民医院洗牙洁牙窝沟封闭蛀牙龋齿怎么样好吗 We all know time is a construct, and right now, it#39;s kept by the very precise tick of an international network of around 500 atomic clocks.我们都知道时间是个复杂的概念。目前,世界上有一个由大约500台原子钟组成的网络,而我们就通过这些原子钟精确的滴答进行计时。But now researchers have shown that time could be kept even more accurately with a new-generation of clocks called optical clocks, and they want to use the new system to redefine a second - which would mean we could squeeze even more into our days. The optical clock they#39;ve just measured is so precise that it would have lost less than two minutes if it had been running since the birth of the Universe, which is pretty incredible once you wrap your head around it.但是现在研究人员表示,新一代钟表——光学钟——可以更准确地计时,而且他们想用新系统来重新定义一秒钟的长度,这也就意味着我们的日子里甚至可以挤进去更多光阴。刚刚测量的光学钟非常精确,如果它从宇宙诞生之日起开始运行的话,到现在误差还不到两分钟,仔细想想简直不可思议。Global time-keeping is important, because #39;the second#39; - as defined by the International System of s (SI) - is what our GPS devices, electrical power grids, and financial networks all rely on.全球计时是非常重要的,因为我们的GPS设备、电网和金融网络全都依赖着由国际计量系统(SI)定义的“秒”。That#39;s why we use atomic - or microwave - clocks, which measure the vibration of a caesium atom to keep time, just like the tiny swinging of a pendulum. And since 1967, a SI second has been defined as 9,192,631,770 cycles of those vibrations. But, as specific as that sounds, even the best atomic clocks can still accumulate an error of about 1 nanosecond over a month.这也是我们应用原子钟或微波钟的原因,它们通过测量铯原子的摆动来计时,就像一个钟摆在轻微摆动。自1967年以来,国际计量系统定义的一秒就是91亿9263万1770次这种微小摆动。但是,尽管听起来很精准,即使是最好的原子钟在一个月的时间内也仍然会积累出十亿分之一秒的误差。Optical clocks, on the other hand, are even more precise. They work similarly to atomic clocks, but they measure the oscillations of atoms or ions that vibrate at frequencies about 100,000 times higher than microwave frequencies - which is a whole lot faster, and therefore more accurate.另一方面,光学钟却更为精确。它们的工作原理与原子钟相似,测量原子或离子的振动,但这些原子或离子的摆动频率大约是微波频率的10万倍左右——这要快得多,因此也更为准确。;Our study is a milestone in terms of practical implementation of optical clocks,; said one of the researchers, Christian Grebing, from the National Metrology Institute of Germany, ;The message is that we could today implement these optical clocks into the time-keeping infrastructure that we have now, and we would gain.;德国国家计量研究所的一位研究人员克里斯蒂安·格雷宾说:“就光学钟的实际应用而言,我们的研究是一块里程碑。也就是说,今天我们可以把这些光学钟纳入目前拥有的计时基础设施之中,而且,我们会有所收获。”That gain is the ability to squeeze more into every second. Us slow humans wouldn#39;t really notice, but things like financial time stamps would be more specific ,and banks would be able to complete even more transactions per second.收获就是可以在每一秒之中挤入更多的时光。我们这些慢腾腾的人类不会真正注意到这点变化,但是金融时间戳之类的东西会更为精准,而甚至会在每秒钟完成更多的交易。 /201606/449951成华区冷光美白喷砂洁牙去哪里医院好乐山市红十字会医院烤瓷牙全瓷牙瓷嵌体多少钱
