1·The authors consider the discovery of PGE anomaly and platina as significant evidence for confirming the meteorite impact event.

笔者认为这种PGE元素异常和粗铂矿的发现是陨石及其撞击作用的重要依据之一。

2·So platina is like a diminutive of silver, but we now know that platinum is far superior to silver It is far more noble. It has a higher melting point, a higher chemical inertness, a fantastic metal.

所以普拉塔就像一个小小的银，但我们现在知道普拉塔比银要好很多,更为珍贵，熔点更高，化学惰性更高，是一种非常不可思议的金属。
