Exact Mass是准确分子量，一般精确到小数点四位 Exact Mass是准确分子量，如果有具体例子介绍一下就更好了:) HBr Exact Mass: 79.93 Mol. Wt:80.91m/e:79.93(100%),81.92(97.3%)
which was expressed as percentage of the original mass, was considered to correspond to the solubility and disintegration of the cement, which was calculated according to this equation: D% = % (W0 – Wt) 每个样品减重,被表示为原始的大量的百分比,被考虑对应于水泥的可溶性和崩解,根据这个等式被计算...
