It is calculated in practice by summing the atomic weights of the atoms making up the substance's molecular formula. 实际计算中是把组成该物质分子式的各原子的原子量求和而得。
The atomic formula is called atom for short in predicate calculus. 在谓词演算中,有时将原子公式简称为原子。
Formula weight: Sum of the atomic weights of all atoms in a chemical formula. 式量:化学术语,即某一化学式中所有原子的原子量之和。
Fitting the atomic scattering factors for electrons to an analytical formula 电子的原子散射因子解析表达式的拟合
VB is the volume ratio of the hydrophilic group to the lipophilic group in the emulsifier molecule, it can be calculated from the constants of elementary atomic sturcture and can be expressed in formula or comes from qualitative and quantitative analysis. VB值是乳化剂的亲水基与亲油基体积比。VB值来源于原子结构的基本常数-鲍林半径,并且可用公式表达、定性分析及定量计算。
