陨星

The Virtual Institute for Exo/Astrobiology devotes to exobiology research in low Earth orbit, search for both extant and extinct life in the solar system, on Mars, and on other planets such as europa, meteorites, comets and micrometeorites so on, origin of life.

该研究所致力于外太空的研究，包括低环地轨道，搜索太阳系，火星，以及其它星体例如木卫二，陨星，彗星和微小陨石上现存的和已经灭绝的生命物质，以及生命的发生。

The planet shows no sign of the plate tectonics, the continental shifts and rumbles that keep the Earth's surface fresh and erase impact craters, but satellite mappers have detected nine so-called hot spots resembling the Hawaiian islands, which are higher and hotter than the surrounding Venusian plains.

地球通过大陆漂移表面不断发生变化，并消去了陨星碰撞坑，而金星上没有迹象表明有板块构造和大陆漂移。不过卫星图片显示有9个像夏威夷群岛一样的所谓&热点区域&，这些区域比周围的金星平原更高些和更热些。

For example, much information comes from the study of meteorites

例如，对陨星的研究可以取得大量的资料。

Unexpectedly, one of the little meteorites came to his help.

意想不到的是，一个小陨星帮助了他。

It is the purpose of this article to examine the possible role of the impact of large meteorites or asteroids in the production of continental nuclei.

本文的目的就是：测试在大陆中心的产生中的大陨星或小行星的冲击的可能角色。

One theory about the existence of extraterrestrial life rests on the presence of carbon compounds in meteorites.

地球外存在生命的理论是基于陨星上存在碳化合物质这一事实的。

The birth of 76 years in December, I bid farewell to China's four meteorites.

76年12月诞生的我，送走了中国的四大陨星。

If there is no burnout is meteorites.

如果没有燃尽就是陨星。

One theory about the existence of extraterrestrial life rests on the presence of carbon compounds in meteorites.

地球外存在生命的理论是根据陨星上存在碳化合物这一事实得出的。

It is rarely found in nature except as a visitor from other worlds in the form of meteorites

在自然界中很少能找到纯铁，除非是把陨星这个天外来客也算上。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
