查询词典 comet

The investigations into this remote area were difficult and the findings yielded many interesting theories, ranging from fairly plausible ideas about the arrival of a stony asteroid or comet, to more exotic hypotheses involving black holes, antimatter, mirror matter, volcanoes, ball lightning, and "geometeors," to really bizarre notions about crippled alien spaceships, laser beams from other planets and death rays secretly invented by Nikola Tesla.

这个偏远地区的困难和调查的结果产生了许多有趣的理论，从大约一个石质的小行星或彗星的到来比较可行的想法，更涉及黑洞，反物质，镜子的问题，火山，球状闪电，和异国情调的假设等&geometeors，&约削弱外来飞船真正奇怪的观念，激光束从其他行星和死亡射线秘密尼古拉特斯拉发明。

When I meet the engine with its train of cars moving off with planetary motion —— or, rather, like a comet, for the beholder knows not if with that velocity and with that direction it will ever revisit this system, since its orbit does not look like a returning curve —— with its steam cloud like a banner streaming behind in golden and silver wreaths, like many a downy cloud which I have seen, high in the heavens, unfolding its masses to the light —— as if this traveling demigod, this cloud-compeller, would ere long take the sunset sky for the livery of his train; when I hear the iron horse make the hills echo with his snort like thunder, shaking the earth with his feet, and breathing fire and smoke from his nostrils（what kind of winged horse or fiery dragon they will put into the new Mythology I don't know）, it seems as if the earth had got a race now worthy to inhabit it.

当我遇见那火车头，带了它的一列车厢，像行星运转似的移动前进，——或者说，像一颗扫帚星，因为既然那轨道不像一个会转回来的曲线，看到它的人也就不知道在这样的速度下，向这个方向驰去的火车，会不会再回到这轨道上来，——水蒸汽像一面旗帜，形成金银色的烟圈飘浮在后面，好像我看到过的高高在天空中的一团团绒毛般的白云，一大块一大块地展开，并放下豪光来，——好像这位旅行着的怪神，吐出了云霞，快要把夕阳映照着的天空作它的列车的号衣；那时我听到铁马吼声如雷，使山谷都响起回声，它的脚步踩得土地震动，它的鼻孔喷着火和黑烟（我不知道在新的神话中，人们会收进怎样的飞马或火龙），看来好像大地终于有了一个配得上住在地球上的新的种族了。

RESULTS MTT assay showed that hydroquinone inhibited the growth of cells in a concentration-dependant manner and the survival number of XRCC1-deficient cell was less than that of the two control groups. Comet assay revealed that different concentrations of hydroquinone caused more severe DNA damage in XRCC1-deficient cell line than in control cells and there were no significant difference in the two control groups.

结果 MTT结果显示，不同浓度10~100μmolL^(-1氢醌作用的XRCC1缺陷细胞，490 nm波长处吸光度值低于对照组细胞，提示缺陷细胞的细胞存活率比正常细胞低；彗星实验结果显示，不同浓度的氢醌对XRCC1缺陷细胞DNA损伤比对照组细胞更严重，而2个对照组细胞之间没有明显差异。

We haveour own intelligent property rights. Among them our spotlight is one of our typical products. It's the first time that the image illumination technology is used on the spotlight in the world. The reachable distance is raised 2-3 times, its beam of light angle is raised 5-6 times, and much power and energyis saved and illumination well-distributed. There is little color difference, comet difference and color difference for a point. Our spotlight can represent the latest technology of the same products in contemporary age and is granted national invention patent and national new practical patent.
