Molecular simulation of hydrates and thermodynamical modelling are of great importance for both fundamental research and hydrate-based applications.Developing novel approaches to study hydrate phase equilibria is thus very interesting and challenging.In some practical applications,such as the use of hydrates in gas separation processes and/or for refrigeration [1],the technologies are based on the formation/dissociation of carbon dioxide hydrates.

南海是我国走向深海研究的重要突破口[汪品先,2009],具有南北张裂型、东侧俯冲型和西侧剪切型三种典型大陆边缘;其东部边界,由于南海洋壳沿马尼拉海沟向东俯冲至吕宋岛弧之下,由西向东,形成了由南海海盆、马尼拉海沟、增生楔、弧前盆地(吕宋海槽)和火山弧(吕宋岛弧)组成的马尼拉海沟俯冲体系[Ludwig et al.,1979;李家彪等,2004];作为南海惟一的俯冲汇聚边界,马尼拉海沟俯冲带是南海完整
南海形成演化有三个问题还有待解决或进一步明确,一是海底扩张的年龄、中央海盆与西南次海盆的扩张次序,二是海底扩张成因,构造逃逸?板块俯冲?或是混合模式?其中红河断裂、海南地幔柱和马尼拉海沟的作用如何?三是南海海盆的关闭与消亡问题.这些问题依赖于磁异常测量、岩浆与岩石学证据和地壳结构探测.
针对南海地质演化中的关键问题之一:大陆张裂和海底扩张模式开展了地球物理研究工作.但是过去由于受制于仪器的束缚,很久以来南海都没有一条完整的穿越洋盆的海底地震探测剖面.由于大部分的 OBS 探测剖面集中于南海北部,影响了我们深入认识海底扩张、大陆张裂过程以及南海的形成与演化.本研究利用国产海底地震仪器研制成功后的第一条深海地震测深剖面数据,开展了南海西南次海盆深部结构的广角地震探测研究工作,为认识该
根据高分辨率地震层析成像资料可知,海南热点之下存在一个直径约为80 km,因大范围地幔对流作用影响而向南东方向倾斜的"海南地幔柱"(Lei et al.,2009).大约32 Ma前,地幔柱头抵达岩石圈底部;随后,地幔柱流一部分沿岩石圈底部裂隙溢出地表形成热点,另一部分沿岩石圈与软流圈分界面向海底扩张中心运移,连同扩张中心处上升流体一块沿裂隙溢出地表.在大尺度区域地漫流作用下,岩石圈之下的地幔柱部
In this study,we present two high-resolution multichannel seismic profiles across the Reed Bank area of South China Sea.
One of the major unsolved questions of the opening of the South China Sea (SCS) is its opening sequences and episodes.To constrain the timing and cause of major tectonic events,we focus on the rifting
Gas hydrates are of great interest in petroleum industry.They are especially a flow assurance issue in deep offshore oilfields.In this study,an experimental work concerning the equilibrium of gas hydr
During the production of natural hydrate fields or end-of-life crude oil and natural gas fields,significant volumes of produced water may result in the formation of a hydrate-in-water slurry.
