Nature, most elements have two or more isotopes, the same kinds of elements in the quality of the various isotopes of different, but the types and proportion constant (except for radioactive elements). In 1961, the carbon content of the most abundant in nature, a kind of isotope, carbon-12 atom of a quantity and quality of C as a 12 mass units to it as "benchmarks" for all isotopes of an element according to the average abundance The ratio of the benchmark is the atomic weight of this non-prime, that is listed in the periodic table of atomic weights.
自然界中大多数元素都有两种或更多的同位素，同种元素的各同位素质量不同，但其种类和比例是恒定的。1961年，把碳在自然界含量最丰富的一种同位素，碳12的一个原子的质C量定为12个质量单位，把它作为"基准"，某种元素的所有同位素按丰度的平均值与基准之比，就是这种无素的原子量，即元素周期表列出的原子量。

In fact, the arithmetic is not set up this way, the quality of nuclear helium than two protons and two neutrons, and the quality of fewer 0.0302 atomic mass unit [57]!
实际上，这样的算术并不成立，氦核的质量比2个质子、2个中子质量之和少了0.0302原子质量单位[57]！

From c. 1900 until 1961, the reference standard was oxygen, with a value of 16, and the unit of atomic mass was defined as 1/16 the mass of an oxygen atom.
大约从1900～1961年，氧曾作为原子量的参考标准，那时指定氧的原子量为16，因而原子质量单位定义为氧原子质量的1/16。

The fragment m/z 132 is 19 amu above the standard fragment mass for leucine or isoleucine, respectively; therefore, one of these amino acids has to be the C-terminal part of the dipeptide.
破片 m/z 132 分别比亮氨酸或亮氨酸残留物的标准破片质量多19个原子质量单位。因此，这些氨基酸中的一个个只能是二肽中的羧基末端。
-
Unit of mass for expressing masses of atoms or molecules.
用于表达原子或分子质量的单位。

If the electric charges in the two stars are supposed to be equal, it can be calculated according to the Kulun's theorem that 19100 nuclear unity masses must have one electron , such that the electromagnetic force produced can provide enough centrifugal force for the rotation.
假定两星所带的电荷数量相等，根据库仑定律，我们可以计算出，在两星中平均每19100个原子单位质量，就必须带有一个电子电荷，所产生的静电引力才能够提供足够的向心力。
