摘　　要：天然气水合物是由水和小气体分子在低温、高压条件下形成的非化学计量性笼型结晶化合物,具有分布广泛、能量密度高、埋藏浅、洁净等特点,有望成为未来理想的新能源。由于水合物样品成分复杂,需要建立相应的谱学手段对其进行系统地分析。基于此,探讨3种常见的谱学手段(X射线衍射、拉曼光谱、核磁共振普)研究天然气水合物的基本物理化学特性。Natural gas hydrates are a class of nonstoichiometric crystalline inclusion compounds formed by water and small gas molecules at low temperatures and high pressure conditions.They have the characteristics of wide distribution,high energy density,shallow burial,and cleanliness,and are expected to become an ideal new energy source in the future.Due to the complex composition of hydrate samples,corresponding spectroscopic methods are needed to analyze them systematically.Based on this,three common spectroscopic methods(X-ray diffraction,Raman spectroscopy,nuclear magnetic resonance spectroscopy)were introduced to study the basic physical and chemical characteristics of natural gas hydrates.
