Armed with this information and further analyses, Rumble, lead author Bekker, and colleagues propose the following scenario today in Science . Early in Earth's history, volcanic eruptions spewed massive amounts of sulfur dioxide into the atmosphere, where UV sunlight broke down the gas and created the odd sulfur isotope ratios. The sulfur descended with the rain and accumulated into sedimentary beds on the sea floor. Once there, superheated water from geothermal vents at various locations on the sea floor cooked the sulfur into sulfide. Finally, nickel-bearing magma welled up from Earth's mantle, combining with the sulfide to form nickel sulfide and encasing the compound inside volcanic rock called komatiite.

凭借这份资料和进一步的分析，朗布尔、研究论文的第一作者贝克及同事们今天在《科学》杂志上提出了如下的推测：在地球早期的历史上，火山爆发将大量的二氧化硫气体喷射到空中，太阳的紫外线将其分解，产生了奇特的硫同位素比值，这种硫随雨降下，积存于海底沉积层中；一旦到达海底，海底各处的地热出口所产生的温度过高的水把硫加热成硫化物；最终含有镍的岩浆从地幔中涌出，跟硫化物结合形成硫化镍，并将硫化镍包裹在一种叫做"科马提岩"的火山岩中。

People have suspected that the Earth might be round since as early as Eratosthenes in 240 B.C.– it was mostly just a bunch of dogmatic nut-jobs who continued to insist that the Earth was a birdbath you could fall off of if you sailed too close to the edge. So by the time Columbus rolled around in 1492, pretty much everybody knew they were dealing with a sphere, Chris included.

早在公元前240年，埃拉脱色尼（公元前三世界希腊数学家、天文学家和地理学家，Syna注）就猜测地球可能是圆的——在当时绝大多数人都固执地认为地球像一个盆子，如果你一直向前走接近地球的边缘就会掉下去，因此直到1492年哥伦布环游地球之前，大家才知道他们是在同一个球状的地球打交道。

Also: to extend the bottom of the central vertical bisector, the earth is flat-line, this line is the Earth's mainland and flat into the marine equivalent of two and a half.

还有∶延长在底面中央的纵平分线，就是地球的子平线，这条线正好把地球的大陆和海洋平分成相等的两半。

If teaching " birthplace " one class hour, inspiring a student to ponder over an answer middleaged intercalary earth and teenager bissextile earth are outward appearance, expression, words and deeds, disposition, right " I " with opposite the respect such as vivid manner has why on the foundation of change and metabolic reason, the teacher is umbriferous show design of whole writing on blackboard.

如在教《故乡》一课时，在启发学生思索回答中年闰土和少年闰土在外貌、神情、言行、性格、对"我"和对生活态度等方面有何变化以及变化原因的基础上，教师投影显示出完整的板书设计。

The motive behind this is unclear, though it has been theorised that they wished to pillage our world for its natural resources. Race X's invasion was a campaign of opportunity, and there have been no instances of Race X activity on Earth since the destruction of Black Mesa, presumably because after the nuclear blast the Black Mesa area was an inhospitable environment, and the Earth as a whole lost its appeal as a target once it was conqured by the Combine.

虽然以推断出它们希望掠夺这个世界的自然资源，但是在此背后的动机是为了核能。X族的入侵是一个战役机会，而且在黑山基地毁灭前并没有X族在地球活动的先例，可能是因为在核爆炸以后，黑山地区变成了不适合居住的环境，作为曾被联合军征服过的目标，地球已完全失去了自身的吸引力。

The bottom line is that no dragon's breath of flame will stretch across 100 million miles of space and blowtorch Earth. The largest solar flare recorded to date, on Nov. 4, 2003, spewed several billions of tons of plasma in Earth's direction.

太阳磁场变化确实会造成强大的火焰，而虽说下一轮峰值的确在2012、2013年左右，强度也会比上一次增强30-50%，这也不是有记录以来人类历史上最大的一次太阳磁场。

The method comprises steps: dissloving relative rare earth oxidant into nitrate to prepare rare- earth azotic acid solution, adding solid nitrate, boracic acid, citrate and urea according to proportion, mixing, calcinating with burning method and getting final product.

制备时，将相应的稀土氧化物溶于硝酸，配成稀土硝酸盐溶液，按计量比加入固体硝酸、硼酸、及柠檬酸与尿素，混合均匀，利用燃烧法灼烧，即得产品。

Presumably if all life on Earth were extinguished, the Earth's atmosphere would fall back to a persistent equilibrium, and become as boringly predictable as Mars and Venus.

可能要等地球上所有的生命都寂灭之后，地球的大气才会回降至持续平衡状态，变得像火星和金星那样沉闷。

The Brahe theory stated that all of the planets except the earth revolved around the sun, which in turn revolved around the earth. Brahe's assistant, German astronomer Johannes Kepler (1571-1630), used induction to analyze the data collected by Brahe over a twenty-year span. Kepler supported the heliocentric theory by proposing three laws of plant revolution.

在哥白尼思想的影响下，泰革(Tycho Brahe， 1546-1601)在观察的基础上，提出了哥白尼式的地心说︰地球以外的行星都绕太阳转；但太阳及其行星都绕地球转﹗泰革的助手、德国天文学家凯普勒(Johannes Kepler， 1571-1630)用归纳法分析泰革二十年积累的数据，提出了"行星运行三大定律"，支持了日心说。

This earth is ours, it is not the earth of the Brahmin, the Russian or the American.

地球是我们的，它不是婆罗门的地球，俄国人或者美国人的。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
