The binding of ligands to proteins occurs mostly through weak non-covalent interactions, namely hydrophobic interaction, van der Waals forces, and hydrogen bonding.

蛋白和配体间的作用通常是通过弱非共价键力的相互作用而实现的，如疏水作用、范德华力和氢键。

Intermolecular weak interaction studies of nitric oxide dimer can deepen our understanding mechanism of the weak interaction, and master the law of the non-hydrogen bonding weak interaction.

对一氧化氮二聚体分子间弱相互作用的研究可以加深我们对分子间弱相互作用机制的理解，从而进一步掌握非氢键类型弱相互作用的规律。
