Lattice dynamical simulations of noble gas hydrate structures I and II have been performed. Potential energies were investigated to study the influence of guest species on the stability of the hydrate structure. Results show that when the diameter of inclusion molecules is between 3.A and 4.2 A, such as Ar and Kr, the critical role of the 512 cage in the stabilization of hydrates becomes effective. For Xe hydrates SI and SII, with the help of lattice dynamical calculations, the modes attributions are identified directly. We proposed the resonant effect of the fingerprint frequency at about 7 meV and 10 meV which arise from the coupling of Xe molecules in the 512 cage with the host lattice.

浅地层剖面技术是应用声学原理高效获取海底面之下浅部地质地球物理信息的探测技术,主要应用于海底浅地层信息探测和海底特殊目标调查等方面。以往研究者主要集中在浅地层剖面的具体应用,未对不同类型的浅剖应用效果进行综合对比分析,本文比较4种不同类型浅地层剖面系统的组成、工作方式和探测技术参数,认为不同尺度的探测目标需要应用不同类型的浅地层剖面系统。分析和对比不同震源类型浅剖的应用案例,发现电火花震源穿透能力最强,分辨率随工作频率的增大而提高;电磁式震源穿透深度与分辨率适中;压电换能器震源分辨率较高,穿透能力弱;参量阵震源利用差频原理,信号中包含高频与低频两部分,能够同时得到较高的分辨率与较大的穿透深度。未来浅地层剖面探测技术向深穿透、高分辨率、高效率、二维向三维甚至高维探测方面发展。
