The result shows that large airgun source excited in reservoir environment is rich in low frequencies (0 Hz), and is effective to produce waves with long-offset and deep crustal penetration.

试验结果表明，大容量气枪震源是具有丰富的10Hz以下低频信号的低频震源，其激发的地震波具有传播距离远，穿透深度深的特点。

A field experiment using large volume airgun source was conducted in an onshore reservoir. The characteristics of the waveform and its propogation has been studied.

利用大容量气枪震源在陆上水库进行地震波激发试验，研究陆上水库环境下激发气枪震源所产生的地震波特征及传播距离。

This project also compared and discussed the research results of OBS and onshore-offshore experiments in nearby areas. The conclusion is that the active airgun source is equivalent to an earthquake of about magnitude 0.5, and the airgun signals can be detected at the maximum distance of only about 250 km, which is not enough for the study of deeper lithospheric structure below the crust. Furthermore, the onboard airgun source and MCS streamer are difficult to operate in the shallow water of reef and island areas.

本项目还分析对比了周边地区海底地震仪探测和海陆联合地震探测的研究成果，发现人工气枪震源约相当于0.5级的天然地震，其信号传播距离最远只有250 km左右，很难探测到地壳以下更深部的岩石圈结构特征，此外船载的气枪震源和多道电缆在岛礁区和浅水区很难开展工作。

A recent study by the London-based International Institute for Strategic Studies concluded that China was also close to beginning the production of aircraft-carriers, which would give it the ability to project airpower over great distances.

总部位于伦敦的国际战略研究所最近的研究表明，中国也在接近开始生产航母，这使其有能力将空中力量投送至更远的距离。

He was placed on a plane which took off from an airstrip in Nigeria half a world from here.

他的遗体被搬到飞机上一架从尼日利亚起飞的飞机，离这里有半个星球的距离。

Up to 48 per cent of students have their own vehicle, an Alamo Rent A Car survey revealed. And 79 per cent travel over 100 miles a week, compared with 64 per cent last year.

多达48%的学生拥有自己的私人机动车，其中79%的学生每周行驶距离超过100英里，与去年的64%相比有明显增加。

The albedo, diameter, and distance of such objects together determine their brightness.

这种物体的反照率、直径和距离是决定其亮度的因素。

You know Aldebaran is not a true member of the Hyades cluster because – at 65 light-years – it is so much closer to us.

你要知道毕宿五其实并非毕星团的一员，因为65光年的距离，它更接近我们。

But Mars is just a little nearby hunk of rock in our own solar system – while Aldebaran is a mighty star, located about 65-light years away.

但是，火星只是太阳系中离我们较近的一块大岩石，而毕宿五则是距离我们有65光年的一颗神奇的星球。

If you match up against Aldridge with a center, he'll face you up on the perimeter.

如果中锋和他对抗，他将把你推到中距离。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
