UNDAUNTED BY SKEPTICISM, a handful of scientists continues to look for potential impact craters and tracers.
有一群科学家没有因为其他学者的怀疑而丧志，继续搜寻可能的撞击坑与撞击遗迹。
4.
That indicates that scattered rocks associated with young impact craters are more likely the causes of the high CPR.
这表明与年轻的撞击坑相关的散布碎石很可能是高CPR的原因。
5.
Mercury is covered in craters - hollows made by huge space rocks crashing into it.
水星的表面有许多陨石坑，这些坑是由巨大的太空岩石撞击而成的。
6.
It is about7000 million years old measured by isotope geological method.
假如该坑与上述三个陨石坑是同一系列的外来天体撞击地球事件。

8.
Massive meteorite strikes continued for hundreds of millions of years, some blasting craters more than1,000 kilometers in diameter.
巨大陨石的撞击持续了几亿年，有些撞击所产生的陨石坑，直径超过1000公里。
9.
Successive impacts would create a large number of metamorphosed regions in the vicinity of craters.
连续的撞击会在陨石坑附近，造成很多变质的区域。
10.
The age of each flow can then be determined by measuring its density of impact craters.
岩浆流的个别年龄可以藉测量其撞击陨石坑的密度而决定。
11.
The great force of the meteor hitting the earth left a very big hole.
流星下落时的巨大冲力撞击到地面上，形成了一个大大的坑。
12.
Geologists agree that the Sudbury impactor was at least eight kilometers( about five miles) across.
地质学家同意，造成陨石坑的外太空撞击物，直径至少八公里。
13.
They estimated it would leave a crater hole in the surface between one and two kilometers across.
他们估计，这一撞击在月球表面留下了直径为一到两公里的陨石坑。
14.
Because shock energy attenuates rapidly in porous materials, an impact can heat the rocks bordering the deep crater very efficiently.
因为冲击波的能量在多孔隙物质中快速减弱，撞击能使上述深陨石坑附近的岩石有效加热。
15.
Knowledge of the impact location allowed us to reconstruct the trajectories and distribution of material ejected from the crater and evaluate the extent of the fires.
对撞击地点的了解，让我们重建物体从陨石坑喷出的轨迹与分布，并评估燃烧的程度。
16.
Older mare flows have been exposed to bombardment longer than younger flows, so they have higher crater densities.
较古老的月海岩流受到撞击的时间比年轻岩流久，因此它们的陨石坑密度较高。

Break, break, break On thy cold gray stones, O sea!
撞击，撞击，撞击大海啊，在冰凉灰色的岩石上迸溅！
18.
Break, break, break At the foot of thy crags, O Sea!
撞击，撞击，撞击，大海啊，在险崖峭壁下迸溅！
