摘要

对氢键材料进行了太赫兹时域谱分析，研究了材料在太赫兹频率范围内的介电和光学特性。测量了H2O冰、D2O冰、丙烷水合物、SF6水合物和CH4水合物在0.4 ~ 1.2 THz频率和20 ~ 240 K温度范围内的复介电常数ε′和ε′。我们用数学模型讨论了ε'和ε'与频率和温度的关系，得到了具体的参数。这些结果表明，用冰的数学模型来分析天然气水合物的介电常数是可行的。

Terahertz characterization of hydrogen bonded materials

Terahertz time-domain spectroscopy of hydrogen bonded materials was carried out to investigate the dielectric and optical properties of materials in the THz frequency range. The complex dielectric constant (i.e., ε' and ε") of H₂O ice, D₂O ice, propane hydrate, SF₆ hydrate and CH₄ hydrate was measured at frequencies in the range 0.4-1.2 THz and temperatures in the range 20-240 K. We discuss the frequency and temperature dependence of ε' and ε" using a mathematical model to obtain specific parameters. These results show that it is possible to analyze the dielectric constants of gas hydrates using a mathematical model of ice.
