淮安中山医院做人流多钱淮安市中医院治疗腹胀多少钱淮安五个月做人流 When Spotify raised more than 0m this month in a funding round that valued the music streaming company at .5bn, investors played down the risk of it being crushed in a bruising battle with Apple.本月,当Spotify在一轮融资环节中筹资逾5亿美元时,投资者轻看了该公司在与苹果(Apple)的残酷交锋中被击败的风险。此次融资对这家音乐流媒体公司的估值为85亿美元。After all, the Swedish start-up was on a roll. Subscriber numbers had doubled over the past year to 20m, up from 15m in January, giving the company a big lead over rivals in the race for control of the fast-growing market.毕竟,这家瑞典初创企业好事连连。过去一年,Spotify付费用户数量增加一倍,至2000万,1月时付费用户数量还是1500万,这令该公司在控制这个增长迅速的市场方面远远领先于竞争对手。But on Sunday, Apple gave the clearest signal yet of its ambition to dominate this nascent market at almost any cost — even if that means burning through a portion of its 0bn cash pile in the process.但上周日,苹果(Apple)发出了迄今为止最明确的信号,将以几乎任何代价主宰这个新兴市场,即便这意味着在此过程中苹果要耗费其2000亿美元现金储备中的一部分。Apple’s decision to splash more cash in their direction has been welcomed by people in the music business, but it represents an ominous development for Spotify. The lossmaking company was aly under pressure from rights holders — including Ms Swift, who pulled her songs from the service last year.苹果希望在该领域投入更多资金的决定受到音乐界人士的欢迎,但对于Spotify而言,这是个不好的征兆。这家亏损公司已面临版权所有者的压力,包括泰勒#8226;斯威夫特(Taylor Swift),去年,她从Spotify撤下了她所有的歌曲。Mark Mulligan, analyst at Midia Research, says Apple’s move to pay higher royalty rates than Spotify may be a calculated move to put pressure on the market leader.Midia Research分析师马克#8226;穆里根(Mark Mulligan)表示,苹果付的版税费用将高于Spotify,此举可能是苹果在有意向这位市场领军企业施压。One danger is that Spotify may be forced to match Apple’s payments to the music industry. For Spotify’s investors, this would be a disaster. Earlier this month Apple said it would pay as much as 73 per cent of Apple Music’s revenues to record labels and music publishers — beating Spotify by three percentage points.一种危险是Spotify可能会被迫与苹果付的版税一致。对于Spotify的投资者而言,这将是一场灾难。本月早些时候,苹果表示,将最多把苹果流媒体务Apple Music收入的73%付给唱片公司和音乐发行商,比Spotify高出3个百分点。Mr Mulligan says it is entirely possible that Spotify will be able to capitalise on its first-mover advantage and reach 35m subscribers within five years, which would give it more than half the paid-for streaming market.穆里根表示,Spotify完全有可能利用先发优势,在5年内获得3500万付费用户,占领超过一半的付费音乐流媒体市场。However, he cautions that it is also easy to envisage a scenario in which Apple overtakes Spotify. Whichever company comes out on top, he warns that Spotify will need to find a way to cut dramatically its costs as “the current model is not commercially sustainable”.然而,他警告称,苹果取代Spotify的可能性也很大。他警告称,不管是哪家公司登顶,Spotify都需要设法大幅削减成本,因为“目前的模式在商业上是不可持续的”。 /201506/382739淮安中山妇科医院预约

淮安前列腺医院The Water一driven Armillary Sphere漏水转浑天仪In the middle of the Eastern Han Dynasty, Zhang Heng,an outstanding astronomer, made bold innovations to the armillary sphere,and de-signed and made the first water-driven armillary sphere in the world to measure the position of celestial bodies,which was carved with known important astronomical phenomena. People could observe the movement of the sun,the moon and the stars.汉中期,杰出的天文学家张衡对浑仪作了大胆创新,设计并制作了漏水转浑天仪。张衡还制造出了世界上第一架测量天体位置的水运浑天仪,凡是已知的重要天文现象,都刻在这架仪器上。人们可以通过浑天仪观测到日月星辰运行的情况。To enable the armillary sphere to rotate,Zhang employed the gear system,linking the celestial globe with the kettle clepsydra. Powered by the water leaked out of the kettle,the gear drove the celestial globe to rotate around the axis,one day per circuit, in synchronization with the celestial body(sun).In this way,the celestial changes were presented accurately.By observing the instrument,one could know when a star rose in the east and set in the west.漏水转浑天仪的主体是一个代表天球的球体模型。球里面有一根铁轴贯穿球心,轴的方向就是天球的方向,也是地球自转轴的方向。轴和球有两个交点,一个是北极(北天极),一个是南极(南天极)。为了让浑天仪能自己转动,张衡采用齿轮系统把浑象和记时用的漏壶联系起来,用漏壶滴出来的水的力量带动齿轮,齿轮带动浑象绕轴旋转,一天一周,与天球同步转动,这样,就可以准确地把天象的变化表示出来。人在屋子里看着仪器,就可以知道某星正从东方升起,某星就要从西方落下。The world’s first water-driven astronomic instrument with explicit historical re-cords,the new armillary sphere employed an extremely complex gear system. It was a proud achievement for ancient Chinese people to work out such a complex instrument. Unfortunately,the driving system was not handed down,as made in the remote past.漏水转浑天仪是有明确历史记载的世界上第一架用水力驱动的天文仪器。浑天仪应用到的齿轮机构和凸轮机构十分复杂。远在1800多年前,中国古人就可以造出这样复杂的仪器是很值得自豪的。可惜的是,这套复杂的传动系统因为年代久远没有能够流传下来。 /201511/409370 Q. Why are snowflakes usually perfectly symmetrical? How does one arm “know” how the other arms are growing?问:为什么雪花通常完全对称?其中一瓣怎么“知道”其他几瓣在怎么成长呢?A. “The growth of a snowflake is sensitive to its immediate environment, especially the temperature and humidity,” said Kenneth G. Libbrecht, chairman of the physics department at the California Institute of Technology, who maintains a website explaining snow crystals. “It might take a half-hour for the crystal to reach its final size, and during that time it could travel a mile or more, experiencing ever-changing conditions. 答:“雪花在形成过程中对周围环境非常敏感,特别是温度和湿度,”加州理工学院物理系主任肯尼思·G·利布雷希特(Kenneth G. Libbrecht)说。他开设了一个网站,专门解释雪晶。“雪晶大概需要半个小时才能最终形成,在那段时间里,它能飞行一英里多,经历不断变化的环境。”“If you look at an individual arm, its shape reflects the exact history of its travels,” he said. “But the six arms all travel together, so they all experience the same history. Thus they appear to grow in synchrony, even though no arm ‘knows’ how the others are growing.”“如果你只看单独的一瓣,它的形状反映着自己的旅行历史,”他说,“但是这六瓣一起旅行,所以它们经历的历史是一样的。因此,它们似乎是同步成长,虽然哪一瓣也不知道另外几瓣在怎样成长。”Dr. Libbrecht compared the process to going outside on a cold day, wearing a heavy coat and seeing everyone else wearing one as well, without foreknowledge or consultation.利布雷希特把这个过程比作冷天穿厚外套出门,你会看到其他每个人也都穿着厚外套,但是没人能预见未来,也没人相互商量。“The flip side of this story is that no two snowflakes follow exactly the same path in the turbulent atmosphere, and this is why no two snowflakes are exactly alike,” he said.“这个故事的另一面是,在混乱的环境中,没有两片雪花的成长环境是完全相同的,所以不存在一模一样的两片雪花,”他说。“Finally, snowflakes are in fact not usually perfectly symmetrical,” he said, “although snowflake photographers like to select the ones that are.” Large, beautifully symmetrical crystals are actually quite rare, he said, but “as with people, the most attractive snowflakes tend to get the most attention.”“最后要说的一点是,实际上雪花并不总是完全对称,”他说,“不过,摄影者喜欢选择对称的雪花。”他说,美丽、对称的大雪晶实际上非常罕见,但是“最好看的雪花总是最引人注目。” /201501/356818淮安做人流哪比较好淮安女子无痛人流医院
