It appears as a single-shelled icosahedron with 112 characteristic two-layer spikes.

该病毒仅有单层衣壳，病毒离子呈二十面体对称，二十面体的十二个顶点均有双层突起。

In addition nC〓, nC〓, two isomers of C〓 sterene and three isomers of C〓 isoprenoid hydrocarbons were also identified from aliphatic fraction of pyrolyzed product at 200℃. After pyrolyzed at 300℃, the main aliphatic hydrocarbons were normal alkanes ranged from C〓 to C〓, with C〓 as the main peak and C〓 as the second main peak. Meanwhile, pristane, phytane and C〓 sterane were also detected. In the pyrolysates at 400℃ and 500℃, the content of saturated hydrocarbons decreased, the range of normal alkanes distribution became narrow and the main peak was nC〓. Low concentration of C〓-C〓 steranes was detected and the content of C〓-C〓 increased more.

在200℃热模拟产物饱和烃馏分中除检测出两种长链烯烃外，还检测到正十九碳单烯烃、正三十五碳双烯烃、两个碳二十八甾烯的同分异构体和三个C〓类异戊二烯烷烃化合物同分异构体。300℃模拟产物饱和烃主要为正烷烃，正烷烃的碳数分布范围为C〓-C〓，以C〓为主峰、C〓为次主峰；另外，样品中还检出姥鲛烷、植烷和C〓甾烷等化合物。400和500℃热模拟产物中的饱和烃含量下降，正烷烃系列碳数分布范围变窄，主峰碳后移至C〓，检测到低浓度的C〓-C〓甾烷系列化合物，另外，C〓-C〓藿烷系列化合物含量进一步增加。

From these two incontrovertible premises he deduced that the Library is total and that its shelves register all the possible combinations of the twenty-odd orthographical symbols (a number which, though extremely vast, is not infinite): Everything: the minutely detailed history of the future, the archangels' autobiographies, the faithful catalogues of the Library, thousands and thousands of false catalogues, the demonstration of the fallacy of those catalogues, the demonstration of the fallacy of the true catalogue, the Gnostic gospel of Basilides, the commentary on that gospel, the commentary on the commentary on that gospel, the true story of your death, the translation of every book in all languages, the interpolations of every book in all books.

包括句号，逗号，空格号，字母表的二十二个字母。他还引证了一个被所有的旅行者认同的观点。那就是：在这个庞大的图书馆中，没有两本书是完全相同的。从所有这些无可辩驳的假定中，他推断出：图书馆容纳了一切事物，它的书柜包含了这二十多个拼写代号的所有可能的组合。（组合的数目，虽然很大，但不是无限的。）它们就是我们所有语言可以表达的事物的总和。包括关于未来的缜密历史、天使长的自传、图书馆的真实的目录、数千种错误的目录、这些错误目录的谬误性的展示以及真实目录的谬误性的展示、巴士底的诺斯替教的教义、对这个教义的评说、对这个教义评说后的评论、对你的死亡的真实记录、用各种语言写成的每本书的版本以及每本书的改编本。

Their developing process went through four major periods. They are the germination period in ancient Greece, the forming period from 17 century to 19 century, the revival period during 1920"s and 1930"s in America, and the whoopee period during 1970"s and 1980"s which the contemporary naturalism philosophy of science developed sufficiently.

其发展大致经历了四个时期：古希腊萌芽时期；十七——十九世纪的形成思潮时期；二十世纪二、三十年代在美国的再度兴起以及在同世纪七、八十年代得以充分发展的当代自然主义科学哲学。

Inquiries were instituted, and on consulting the tariff of commissions posted in the convict's parlor, it was learned that the fifty sous could be analyzed as follows: three commissions; one to the Pantheon, ten sous; one to Val-de-Grace, fifteen sous; and one to the Barriere de Grenelle, twenty-five sous.

经过调查，并参照张贴在犯人会客室里那张办事计费表加以研究之后，终于知道了那五十个苏是这样分配的：三件事，一件是在先贤祠办的，十个苏；一件是在军医学院办的，十五个苏；一件在格勒内尔便门办的，二十五个苏。

Results Eleven compounds were obtained and identified as sarcodonin A, scabronine B, 3β-hydroxy-5α, 8a-epidioxyergosta-6, 22-dien,(22E, 24R)-ergosta-7, 22-diene-3β, 5α, 6β-triol,(22E, 24R)-ergosta-7, 22-diene-3β-ol, benzoic acid, 4-hydroxylben-zaldehyde, 4-monopropanoylbenzenediol, ethy1-β-D-glucopyranoside, thioacetic anhydride,(2S, 2'R, 3S, 4R)-2-(2-hydroxyoctadecanoylamino) docosane-1, 3, 4-triol.

结果共分离鉴定了11个化合物，分别是：sarcodonin A、scabronine B、3β羟－5α，5α-过氧麦角甾－6，22-二烯－3β-醇、(22E，24R)-麦角甾－7，22-二烯－3β，5α，6β三醇、(22E，24R)-麦角甾－7，22-二烯－3β-醇、苯甲酸、对羟基苯甲醛、对羟基苯甲酸乙酯、乙基－β-D-吡喃葡萄糖苷、硫代乙酸酐、（25，2'R，3S，4R）-2-（2-羟基－十八碳酰胺）二十二碳烷－l，3，4-三醇。

It was now Harvest, and our Crop in good Order; it was not the most plentiful Encrease I had seen in the Island, but however it was enough to answer our End; for from our 22 Bushels of Barley, we brought in and thrashed out above 220 Bushels; and the like in Proportion of the Rice, which was Store enough for our Food to the next Harvest, tho' all the 16 Spaniards had been on Shore with me; or if we had been ready for a Voyage, it would very plentifully have victualled our Ship, to have carry'd us to any Part of the World, that is to say, of America.

收获庄稼的季节到了，我们的收成不错，尽管这不能说是岛上的丰收年，但收获的粮食也足够应付我们的需要了。我们种下去的二十斛大麦，现在居然收进并打出来了二百二十多斛；稻米收成的比例也差不多。这些存粮，就是那边十六个西班牙人通通到我们这边来，也足够我们吃到下一个收获季节；或者，如果我们准备航海的话，也可以在船上装上足够的粮食。有了这些粮食，我们可以开到世界上任何地方去--我是说，可以开到美洲大陆的任何地方去。

Citation needed In recent decades, most of the new borrowings or coinages have been technical or scientific terms; terms in everyday use are more likely to be derived from existing words (for example komputilo , from komputi ), or extending them to cover new meanings (for example muso , now also signifies a computer input device, as in English).

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
