物质形态具有多样性:从月球到茫茫星云,从漠漠平川到高山、大海……然而,构成这一切的化学元素的种类却是极其有限的,天然存在的元素一共有92种,加上极少量的人造元素,也不过一百多种。然而整个宇宙大厦,就是由这些种类不多的“砖块”建造起来的。 The material forms are diverse: from the Moon to the Nebula Clouds, from the plains to the mountains, to the sea... However, the types of chemical elements that make up all these are extremely limited, with a total of 92 naturally occurring elements, plus a very small amount. There are only a hundred kinds of man-made elements. However, the entire cosmic building was built from these few “bricks.”
