键力常数

By means of the improved electrostatic three-center model of diatomic bonds and its expressions for physical quantities, the relations between effective bond charge density, bond-stretching force constant and characteristic frequency are fitted.
本文应用修正的双原子键三中心静电模型及其有关物理参量表达式，拟合了有效键电荷稠度与键的力常数和特征频率之间的关系；
The infra-red absorption frequency and the vibration strength of an organic molecule depend on the force constant of its specific chemical bond, while the force constant concerns the way in which the electrons are distributed in the molecule.
有机化合物分子对红外光吸收频率和振动强度决定于功能团化学键的力常数，力常数与分子中电子分布有关。
With the ratio of bond angle force constant and bond length one increasing, the crystallized mode softens and makes the structure unstable, finally led to sublimation or melting of the crystal.
体系的键角和键长力系数之比增大时，晶化模软化使结构不稳定，导致其升华或熔解。
