The author hopes that this work can provide a reference for further research and could do well for reducing the multiplicities of geophysical interpretation for the exploration and practice.

希望给后续的正反演研究工作提供科学的依据和参考，在减少地球物理多解性方面做一些有益的探索和实践。

This paper briefly introduced the progress in time-lapse seismic as shown from the 76th SEG annual meeting. Topics include the repeatability of time-lapse seismic, in which we discussed the effects of shooting and receiving environments on repeatability, the effects of the cable length and its positioning accuracy and stability on repeatability, and the data processing techniques to improve repeatability, new insights into time-lapse seismic, in which we described tube wave time-lapse response, spectral decomposition, and time-lapse VSP monitoring, and problems related to application of time-lapse seismic technology. The comprehensive applications of time-lapse seismic and other geophysical data were demonstrated with the real data from an oilfield. Finally, we summarized the difficulties in using time-lapse seismic and outlooked its future trend.

简要介绍了第76届SEG年会反映的时移地震技术的进展，主要内容有：时移地震的可重复性，讨论了激发、接收环境对可重复性的影响，海上拖缆长度、定位精度及排列稳定性对可重复性的影响，以及通过数据处理技术提高数据的重复性；时移地震技术的新领域，讨论了管波时移地震监测、谱分解技术和时移VSP监测等；简要分析了时移地震技术应用中应该注意的问题，并通过时移地震在某个油田的实际应用，讨论了时移地震技术与其他地球物理手段的综合应用；最后分析了时移地震技术目前存在的问题，展望了其发展趋势。

"Taliks form when the downwelling summer heating wave extends deeper than the corresponding winter cooling wave, thereby preventing the talik from refreezing in winter and permitting heat to accumulate at depth as soil ice melts," the scientists said in their study to be published in the journal Geophysical Research Letters.

&由于在地壳板块压力下下降的夏季暖流比相应的冬季寒流沉潜得更深，居间不冻层得以形成，也因此居间不冻层在冬季能够不再结冰，保证土壤中的冰融化时热量在地底深处也能够流通。&研究人员在这份发表于《地球物理学通信》杂志的研究论文中写道。

In the field, we found breaks and fissures of concrete wall on the Wanan river embankment along the surface scarps of the fault,consistent with geophysical surveys.

在万安溪河道附近，并没有线形崖的生成，推测是由於万安溪的河流侵蚀堆积营力大於断层抬升的速率造成。

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）。

Mine transient electromagnetic method is one of mainly geophysical methods, which are used to predict water inrush structures nearby the roof, bottom and driving face in roadway. Compared with ground transient electromagnetic method, this technique has many advantages: high resolution, small volume effect, flexibility and high efficiency. However, relatively slow development of its fundamental theory makes it become an immediate problem to be solved.

矿井瞬变电磁法勘探是预测巷道顶、底板和掘进工作面附近突水构造的主要物探方法之一，与地面瞬变电磁法勘探相比，该方法具有分辨率高、体积效应小、灵活和高效等优点；但其基础理论的发展却相对滞后，使之成为矿井瞬变电磁法勘探技术中亟待解决的问题。

Based on the characteristics of Karst developing in the dam site, engineering geologic mapping, core drilling, adits exploring, geophysical investigation as well as a large amount of hydro geologic test and rock mechanic test have been finished during the course of the karst investigations.

根据武都水库的坝基岩溶较为发育的工程地质特点，在勘察过程中，采用了工程地质测绘、调查、钻探、平硐以及先进的物探测试手段，同时进行了大量的水文地质和岩体力学试验。

"They are becoming brighter and seem to be coming to lower latitudes than in the past," James Russell, principal investigator for NASA's Aeronomy of Ice in the Mesosphere satellite, said last week at an American Geophysical Union meeting in San Francisco.

&这些云已经开始变得更亮，而且比起从前它们有逐渐向低纬度地区移动的趋势，&美国国家航天局冰高层大气中间层卫星首席研究员James Russell在上周于旧金山召开的的美国地理联盟会议上谈到。

In the days of sailing vessels the crew were afraid they would be becalmed on the ocean.
