| 1. | Often icy moons in the outer solar system boast large impact craters 通常太阳系外围冰冷的月亮上有比较大的碰撞坑。 |
| 2. | 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。 |
| 3. | Impact craters have some special features , for example , there are some ray systems and central mountains 撞击坑典型的特徵包括辐射纹和坑中心的小山丘。 |
| 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. | On a simulated lunar surface , visitors can create impact craters by dropping " meteorites " . a cross - section of a meteorite can also be examined through a microscope in this area 观众可在一个模拟的月球表面投下陨石,看环形山如何形成又可利用显微镜观察一块陨石的横切面。 |
| 6. | The many impact craters that have pocked our moon and earth reveal our solar system can be like a shooting gallery , with asteroids and comets regularly striking planets and their companions 我们的月亮和地球上密密麻麻的碰撞环形山可能和射击场相似,小行星和彗星经常碰撞行星及其伴星。 |
| 7. | Appearing at first glance to resemble the human brain , the natural phenomena that created the unusual texture on the floor of this martian impact crater are currently under investigation 乍看之下,这个火星陨石坑的底部很像是人类的脑部组织,不过造成这个不寻常纹路之自然现象为何,现在仍然在研究之中。 |
| 8. | Despite its flimsiness , tempel 1 has an almost planetlike surface , covered with what appear to be impact craters ( the first ever observed on a comet ) , cliffs , and distinct layers 除了结构松散之外,谭普一号有著近乎行星般的表面,其上满布著像是冲撞后所留下的坑洞(这在彗星上是首次被观察到) 、断崖和多层次结构。 |
| 9. | Dark patches of ancient terrain are broken up by swaths of brighter , younger material , and the entire icy surface is peppered by more recent impact craters that have splashed fresh , bright ice across the surface 黑色古老地形的碎片被更明亮、更新物质分割开,整个冰封的表面不断的被更新的陨石砸出的新鲜、明亮的冰更新着。 |
| 10. | The topographic map produced by clementine ' s laser ranger revealed the astounding dimensions of the spa basin , which stretches 2 , 600 kilometers across , making it the largest impact crater in the entire solar system 克莱门蒂号的雷射测距仪制作的地形图揭露出spa盆地惊人的大小:宽达2600公里,是整个太阳系最大的撞击陨石坑。 |
