For example, H, atomic weight of 100,794 hydrogen, carbon FC atomic weight of 1201, the atomic weight of oxygen O for 1594, Copper Cu for F63546 and so on. F history, had also used the other two kinds of "benchmarks", and there have been two kinds of scales used in parallel .1803 years, J Dalton published the first atomic table, the hydrogen-quality of the original F son as a "benchmark "requiring H, atomic weight is 1. In 1826, JJ Berzelius Tony F are presented to the quality of 116 oxygen atoms O as a" baseline "(scheduled for O, E atomic weight 16), which is has been in use to 1961 "Oxygen unit." 1929, found that the oxygen in nature, in addition to the greatest abundance of 16O, there are a small amount of slightly heavier 17O and 18O two kinds of isotopes, and the different sources of oxygen, its composition is slightly different.

例如氢H的原子量为100794,碳FC的原子量为1201,氧O的原子量为1594,铜Cu为F63546等。F历史上,还曾用过另外两种"基准",并且有过两种标度并行使用。1803年,J道尔顿发表的第一张原子量表,把氢原F子的质量作为"基准",规定H的原子量为1.1826年,JJ贝F采利乌斯提出,以氧原子O质量的116作为"基准"(定O的E原子量为16),这就是一直沿用到1961年的"氧单位"。1929年发现,自然界中的氧,除丰度最大的16O以外,还有少量稍重的17O和18O两种同位素,并且不同来源的氧,其组成也稍有不同。
