The technique essentially measures bond vibration between atoms. As researchers stretch the bond, the vibration changes frequency.
这种技术实际上测量的是原子间键的震动。当研究人员拉伸原子间的键时，震动频率会发生变化。

The molecular geometry and the fundamental vibrational frequency are insensitive to the computation conditions, while the total energy and bond energy are pretty sensitive.
分子几何构型和振动基频对计算条件不太敏感，总能量和键能对计算结果较敏感。

According to comparative tests, treating cement slurry with high frequency electric field can enhance the strength of cement bond by 11 7%.
