I#39;m walking with the gods-I#39;m in the gallery that#39;s got objects from the time when Britain was part of the Roman Empire,around 1,700 years ago.我正穿梭于众神当中,大英物馆中有一个展厅专门陈列约1700年前不列颠处于罗马帝国统治时期的文物,其中有一系列神像:Here is Mars, there#39;s Bacchus with his wine cup, Pan piping on a silver dish... and now I#39;ve arrived at what looks like another pagan god, this time in mosaic.一个小型战神马尔斯,一个端着酒杯的酒神巴克科斯,一个在银盘上吹笛子的潘神,还有一个看起来也像是某个异教神的马赛克图案。It#39;s a shoulder-length portrait.这是一幅齐肩人像,He#39;s roughly life-size, clean shaven, has fair hair swept back, and he#39;s wearing a tunic and a robe tightly wrapped around his shoulders.大小相当于真人,画中人的胡子剃得很干净,金色的头发往后拢着,穿着束胸外衣,长袍紧裹肩头。But which god is this?但这是哪路神明?There#39;s a clue, because this is a man with a monogram.有一个线索,因为有个字母能够揭示他的身份。Behind his head are the two Greek letters chi and rho and that tells me at once who he is, because they#39;re the first two letters of the word Christos, and this is in fact Christ.在他头部后方还有两个希腊字母chi和rho,这让我们立刻了解了这名男子的身份:这是希腊文“christes”的首字母,而我们所看到的正是耶稣最早的图像之一。It#39;s one of the earliest images we have of him anywhere, and it#39;s an astonishing survival-made not for a church in the eastern Mediterranean or in Imperial Rome, but for the floor of a villa in Dorset, somewhere around the year 350.它并非东地中海或罗马帝国的某座教堂的物品,而是公元350年前后多塞特某座别墅的地板装饰,能留存至今极为不易。 Article/201506/380981Today that sounds ridiculous.今日这种说法听来荒唐But two hundred years ago it didn#39;t seem so unlikely.但是两百年前还颇言之成理It was widely believed that当时一般人认为the Earth was only a few thousand years old.地球只有几千年的历史But in the mid-nineteenth century a new science但是19世纪中期was emerging that was painting一股新的科学势力兴起a very different picture of the age of the Earth.并对地球的年龄提出截然不同的见解By looking at the deepest layers of rocks geologists地质学家研究深层岩石后were discovering that the Earth was much older发现地球年龄远超出than anyone had previously imagined.一般人的预期If that was true then the sun also had to如果此言属实have been burning for much,much longer.那么太阳燃烧的时间也应该久得多You can see the strata and the lines in the rock in back of you后方岩石的地层和线条that represent hundreds of代表了millions of years of geological history.好几亿年的地质历史The top of Sacramento Peak up beyond this,我们在更后面的沙加缅度峰上we find fossils that are 300 million years old.找到了有三亿年历史的化石Below Sacramento Peak you#39;ve got more than a kilometre沙加缅度峰下方,有一公里多的地层of these strata that are far older than that.年代比三亿年还久远From the age of these strata geologists knew地质学家藉由这些地层得知that the earth was at least a billion years old.地球的历史至少有十亿年At the same time astronomers thought但天文学家却认为the sun was only 10, 000 years old.太阳只有一万年的历史If the geologists were right then astronomers如果地质学家说得对,那么天文学家had to find some other source for the Sun producing its energy.必须另外想办法解释太阳能量的来源The search for the source of energy寻找持了太阳that could power the sun for billions of years数十亿年的能量来源lasted for nearly a century.持续了将近一个世纪Eventually scientists would find the answer in the forces最后科学家终于在凝聚原子的力量that hold atoms together and in the nature of matter itself.和物质的本质中找到But first you have to know what the sun is made of.但首先我们必须先搞清楚太阳的组成To find that out you need to take a very close look at sunlight.想要得到,必须仔细观察阳光When you take the light from the Sun and pass it through a prism,若让阳光穿过棱镜sp it out into the colours,让阳光分色排列as you look through it you notice that it isn#39;t uniform,你会发现阳光的组成并不一致that there are places that are darker.有些地方比较暗Each of those dark lines is due to a specific chemical element.这些暗沉的线条都代表着特定的化学元素Each element has its own series of lines that are specific to it.每一种元素都拥有一系列专属的线条Each chemical element absorbs light at specific frequencies每种化学元素都会吸收特定频率的光线removing a strip from the spectrum.进而移除光谱上的特定区块As the light passes through the sun,光线穿过太阳时all the elements leave their mark.所有的元素都会留下它们的印记So when the light arrives at the Earth it contains所以抵达地球的光线the complete chemical formula of the sun.包含了太阳的完整化学式If we take the spectrum and sp it out to fine details若是把光谱摊开…and what we#39;ve done here is stacked up我们在这里pieces of the spectrum one on top of each other把几块光谱上下堆叠you see all of these dark areas.你们可以看到这些暗色区域The key to figuring out how much of these elements至于判定元素含量的关键are there is the bth and the depth of the line;则是这些线条的宽度和深度how dark is the line and how broad is it.也就是它们的深浅和宽窄 Article/201503/367263

There are two forms available for vitamin D维生素D补充剂,有两种形式supplements; D2, ergocalciferol and D3,cholecalciferol.分别是维生素D2和维生素D3Vitamin D2 is made by the conversion of a sterol维生素D2由植物和酵母的固醇转化而来found in plants and yeast. Vitamin D3 is the form维生素D3that is produced naturally in human skin是人类皮肤暴露在紫外线B光下自然生成的exposed to ultraviolet B light and occurs在某些动物产品中也存在,例如鱼肝油in some animal products such as cod liver oil在多脂鱼中也存在少量维生素D3and in smaller amounts in other fatty fish例如沙丁鱼和金鱼such as sardines and tuna. Vitamin D3 is维生素D3the most common form used in dietary supplements在膳食补充剂和牛奶等强化食品中and fortified foods such as milk. Unlike calcium是最常见的these two forms are not equal in absorption.与钙不同的是,维生素D3和D2两种形式的Vitamin D3 is metabolized differently than D2吸收效果是不同的,研究表明and research shows it is more effective in在提高活性型维生素D的血清浓度方面raising serum concentrations of the activeD3要比D2更加有效form of vitamin D and is also able to maintain而且能够更加长久地使维生素D保持高水平high levels for longer. More research is needed这个领域还需要做更多的研究in this area but many companies are switching from D2但是很多企业,将D2的生产转向D3to D3 to gain greater benefits from their supplements.从而在钙补充剂中获得更多的利润Let#39;s take a minute to understand how to下面,让我们了解一下calculate the amount of vitamin D and calcium如何通过食物的营养成分标签provided in a food from the nutrition label.计算维生素D和钙的总量One serving of cheerios is equal to一份麦片相当于一杯麦片粥one cup of cereal. The nutrition label麦片的营养标签包括includes data for cereal alone and for the cereal麦片单独的营养数据with half a cup of skim milk because也包括麦片与半杯脱脂牛奶共同的营养数据it is typically consumed with milk. So be sure因为麦片通常与牛奶一起食用to understand which column you are ing.所以一定要弄清楚你看的是哪一列One serving of cereal alone has 100 calories.一份麦片有100卡路里的能量The cereal provides 10% of our麦片为我们提供了daily value of calcium. In order to determine每天所需钙含量的10%how many milligrams of calcium that provides为了弄清楚麦片提供钙的数量you need to know that the daily value for calcium你需要知道人体每日所需要的钙is 1000 milligrams. Once you have that information是1000毫克,有了这个信息后you can calculate how many milligrams in the serving用1000乘以0.10或者10%by multiplying 1000 milligrams by 0.10 or 10%.你可以计算出每份麦片含有多少钙The result is 100 milligrams of calcium结果是每份麦片提供100毫克的钙per serving of cheerios. Similarly a serving同样的,一份麦片提供给你of cheerios provides 10% of your daily value每日所需钙含量的10%of vitamin D. The daily value for vitamin D每日所需维生素D为400IUis 400 IU. To calculate the amount in a serving想计算出每一份麦片提供多少维生素Dmultiply 400 by 0.10. The result is 40 IU of就用400乘以0.10vitamin D per serving. To find结果就是每一份提供40IUa full list of daily values for all nutrients想找到所有营养物质的每日所需含量you can go to the FDA website shown你可以登录屏幕一边FDA网址on the side and search for daily values.来搜索每日食物摄取量Vitamin D plays important roles in many processes维生素D在人体的很多程序上throughout the body. Probably the most都发挥着重要作用well understood function that vitamin D has is in最为人们所熟知的功能the absorption of calcium from the small intestine.就是它帮助小肠吸收钙When vitamin D is inadequate calcium from the diet当维生素D不足的时候is poorly absorbed. Another well characterized膳食中的钙就很难被吸收and important role of vitamin D is to maintain维生素另一个特别而重要的作用就是appropriate levels of calcium and phosphate保持血液中钙和磷酸盐的适当水平in the blood to ensure proper bone formation,进而保正常的骨生成,骨骼矿化mineralization, growth and repair. Vitamin D骨生长和骨修复has other roles that have been less well characterized.维生素D还有其他不为人所知的作用 Article/201508/391102
