A master's or doctoral degree in geophysics, physics, mathematics or engineering may be required for employment as a geophysicist

地球物理学者需要地球物理学，物理，数学或工程学方面的硕士或博士学位。

From the broadest geophysiological point of view, the biosphere is the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere, hydrosphere, and atmosphere.

从最广为流传的地球物理学观点来看，生物圈是地球上所有生态系统的集合，包括了所有生物及他们间的相互关系，所有生物与水圈，大气圈及岩石圈间的相互作用。

Earth Tides is a subject which holds a key position in relation to geophysics, geodesy and astronomy, since it is a phenomenon which consists of an elastic-viscous deformation of the terrestrial globe, and this is caused by the gravitational action of the Moon, the Sun, and other Heavenly Bodies.

固体潮是固体地球在太阳和月亮等天体引潮力的作用下所产生的一种粘弹性形变现象，因而是一门连接地球物理学、大地测量学和天文学的学科。

"There are no troughs of that kind in any of the ice caps on Earth," said Global Surveyor project scientist Arden Albee of Caltech at the AGU press conference.

加利福尼亚理工学院的全球监测工程科学家阿登·阿尔比在美国地球物理学协会的记者招待会上说：在地球的冰冠上没有类似的波谷。

Such terms as " ecological geological conditions " and "state of the ecological geological conditions " are determined; approaches, principles and classification of the criteria and indices used for the evaluation of the ecological geological conditions are characterized; geodynamic and geophysical criteria and indices are described.

文中确定了&生态地质条件&及&生态地质条件的现状&等术语的意义；阐述了用于评估生态地质条件的方法、原理以及标准和指标的分类；论述了地球动力学和地球物理学的标准和指

In order to solve the important and basic problem of the petrogenesis of "Tiantangzhai migmatitic granite" in the core of Dabie orogenic belt, the detailed 1∶50000 regional geological surveying and the big scale dissection of important region (metamorphic rocks, granites and structure), were operated in about 900km〓 area near Tiantangzhai peak. On the bases of the petrology, mineral chemistry, geochemistry of rare earth element and microelement, isotope geochemistry and chronology, physicochemistry, magmatic dynamics, geodynamics, diagenetic simulation, and regional geophysical data, the theory of cooling age and historical geochemistry and the viewpoint of tectonic evolution are applied to study the petrogenesis of Yanshan epoch granites of this region. On the bases of above studies, the process of tectonomagmatic dynamics after indo-Chinese epoch in Dabie orogenic belt is discussed. The important conclusions are gotten

本文针对大别造山带核部&天堂寨混合花岗岩&成因这一重大基础地质问题，在天堂寨一带近900km〓的面积上进行了详细的1∶5万区域地质调查和大比例尺重点区解剖，通过对区内燕山期花岗岩进行岩石学、矿物化学、稀土微量元素地球化学、同位素地球化学和年代学、物理化学、岩浆动力学、地球动力学和成岩计算机模拟等研究的基础上，结合区域地球物理学资料，应用冷却年龄、历史地球化学理论和构造演化观，阐明区内燕山期花岗岩成因，并以此为基础进一步讨论了大别造山带自印支期以来的构造—岩浆动力学过程，取得了如下的重要认识

They found that in regions where the amount of snowfall was low and any snow that did settle was sublimating away, enough dust would have accumulated to change the surface albedo sufficiently so that the Earth absorbed sunlight and thawed ( Journal of Geophysical Research – Atmospheres , DOI: 10.1029/2009jd012007, in press).

他们发现在雪量少或者发生落雪升华的地区，积累了足够的灰尘就可以充分改变地表的星体反照率，这样地球就吸收阳光并解冻了（摘自《地球物理学研究——气象学》DOI： 10.1029/2009jd012007）。

They are employed by petroleum and mining companies, consulting geology, geophysics and engineering firms and by governments and educational institutions or they may be self-employed

Precise measurement of the Newtonian gravitational constant G plays important roles in the fields of the gravitation, geophysics, astrophysics, and cosmology. A torsion balance with timeof-swing method to determine the gravitational constant G is proposed.

Torsion balance ；万有引力常数G的精确测量不仅对于弄清引力相互作用的性质非常重要，而且对于整个理论物理学、地球物理学、天文学和宇宙学等都具有重要意义。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
