啊,今天怎么这么多错别字!!!
[1]《梦溪笔谈》《日月之行》:又问予以“日月之形如丸邪,如扇邪?若如丸,则其相遇,岂不相碍?”予对曰:日月之形如丸。何以知之?以月盈亏可验也。月本无光,犹银丸,日耀之乃光耳。光之初生,日在其傍,故光侧而所见才如钩;日渐远,则斜照而光稍满。如一弹丸,以粉涂其半,侧视之则粉处如钩,对视之则正圆。此有以知其如丸也。日月,气也,有形而无质,故相值而无碍。
[2]NASA《Man in the Moon has \'Graphite Whiskers\'》:PASADENA, Calif. -- In a new analysis of a lunar sample collected by Apollo 17, researchers have detected and dated carbon on the moon in the form of graphite -- the sooty stuff of pencil lead -- which survived from around 3.8 billion years ago, when the moon was heavily bombarded by meteorites. Up to now, scientists thought the trace amounts of carbon previously detected on the surface of the moon came from the solar wind.
[3]《论语·微子》:楚狂接舆歌而过孔子曰:“凤兮凤兮,何德之衰!往者不可谏,来者犹可追。已而,已而!今之从政者殆而!
[4]百度百科“潮汐锁定”词条:潮汐锁定,天体术语,(或同步自转、受俘自转)发生在重力梯度使天体永远以同一面对着另一个天体;例如,月球永远以同一面朝向着地球。潮汐锁定的天体绕自身的轴旋转一圈要花上绕着同伴公转一圈相同的时间。这种同步自转导致一个半球固定不变的朝向伙伴。
