生物圈

It housed up to three men. The habitat was crowded inside. Four small airtight rooms enclosed tubs of hydroponically grown plants anchored under xenon lights.

俄国人管它叫生物圈3号（Bios-3），里面很拥挤，仅可供三人生存。4个小气密室里装进了好几桶无土栽培的植物，用氙气灯照射。

To date, micrometeorology approach based on eddy covariance technique has been regarded as the only direct measurement of material and energy fluxes between atmosphere and biosphere, and has been the key technology of the international flux network.

截止目前，利用微气象学原理的涡度协方差技术是唯一能直接测定生物圈与大气间物质与能量通量的标准方法，成为国际通量观测网络的主要技术。

BUT WHERE BIOSPHERE 2 HAD FAILED, IT COULD HELP SCIENTISTS UNDERSTAND THE MAJOR ECOLOGICAL PROBLEMS THAT PLANET EARTH IS FACING.

但是就是在生物圈二号出现的问题里，科学家们可以找到地球所面临的一些主要的生态环境问题。

Therefore, the discovery of Nanxiong paleontology circles, in order to reveal the mysteries of evolution of the Earth's ancient environment, provides a crucial geographic information, Nanxiong palaeontological layers it has become a treasured Chinese and foreign attention.

因此南雄古生物圈的发现，为揭开地球古环境演化的奥秘提供了具有关键意义的地理资料，南雄古生物层因而也就成为中外瞩目的一块宝地。

Litter decomposition and its nutrient dynamics of a pine forest in Dinghushan Biosphere Reserve were studied in a period of 572 days.

本文报道了鼎湖山生物圈保护区马尾松林凋落物分解及其营养动态的情况。

This project aims to construct new threedimensional structures of the Earth's interior in different scales.

20世纪末，空间对地观测技术的发展，获得了地球表面清晰的图像，使人们可以实时地观测地球水圈和大气圈的结构、状态和运动过程，及其与生物圈的相互作用，这是地球系统科学革命性的进展。

The compositions of cell membrane intact polar membrane lipids of bacteria and Achaea and their applications in the researches of biogeochemistry and microbial ecology are summarized in this paper. The recent progresses of IPLs applications are reviewed, with emphasis on those microorganisms that play a specific role in biogeochemical cycle, such as anaerobic ammoniumoxidizing bacteria, anaerobic methanotrophic Achaea, ammoniaoxidizing Achaea and marine Crenarcheota with tetraether lipids, or those special ecological systems, such as hydrothermal vent, cold seep and marine deep biosphere.

综述了海洋沉积物中细菌和古菌的细胞膜完整极性膜脂的组成特点及其在生物地球化学和微生物生态学等研究中的应用，重点评述了在生物地球化学循环中有特殊作用的微生物，如厌氧氨氧化细菌、甲烷氧化古菌、氨氧化古菌、具有四醚膜脂结构的海洋泉古菌等，或者是一些特殊生态系统，如冷泉、海底深部生物圈等研究中完整极性膜脂应用的进展。

"Bio2 is a synthetic ecosystem, but so is California by now," said Burgess.

&生物圈二号是一种合成的生态系统，而现在的加利福尼亚也是一种合成的生态系统。&
