Hydrates in marine environments are typically found in sea floor sediments with pressures in excess of 100 MPa.The probable phase can be in the marine sediments are a two phase solid hydrate (H) and liquid water (Lw) with no existence of free gas.

重庆市南山老龙洞流域属于典型岩溶槽谷区,近年来该流域地下水污染严重.本文选取老龙洞流域10 个地下水点采集样品,分析水样中的水化学指标和三种重要微生物指标,以了解城市化进程对老龙洞地下河流域水质的影响,探究该地区微生物污染的主要来源.
地层学是系统地球科学领域的基础学科之一,其研究伴随和服务地球科学,得到了迅猛发展,对关键地史转折期和重大地质事件的综合年代学研究已为世界瞩目.地层学正在依据自然规律和研究需要,构建地质学的时间单位谱,提供与人类社会接轨的时间单位和地质时间坐标.国际Earthtime(地时)计划正努力通过对不同定年方法和实验室产生的年龄数据进行校正和整合,逐步提高各种定年的技术和水平." 地时- 中国"(Earth
大洋中脊玄武岩(MORB)的Sr-Nd-Pb同位素组成常用来反映地幔源区同位素的特征,因为一般认为在MORB 岩浆上升过程中可能遭受的洋壳混染作用并不会显著影响其Sr-Nd-Pb 同位素组成.然而,与Sr-Nd-Pb 同位素系统不同,MORB 的Re-Os 同位素系统容易遭受到蚀变洋壳混染的影响.
Classical flash algorithms use compositional estimates to get the component fugacities and fugacity derivatives with respect to composition.With such an approach it is,however,difficult to converge a
The main theoretical tool for the study of clathrate hydrate equilibrium is a theory based on Statistical Mechanics that was developed originally by van der Waals and Platteeuw [Adv.Chem.Phys.2,1 (195
In order to design separation processes such as natural gas purification or CO2 capture from flue-gas streams,accurate thermodynamic,transport and kinetic properties are required for all the involved
Recently there have been studies regarding the effects of ultrasonic waves on the formation and dissociation of gas hydrates.There was a report on the formation kinetics where ultrasonic waves were fo
Experiments of gas hydrate formation and decomposition were carried out in a semi-batch stirred vessel at the constant pressure and temperature.The hydrate formations were conducted with methane at va
Clathrate hydrates are crystalline compounds enclosing guest molecules in cages that are formed by hydrogen bonded water molecules [1].They are relevant to a number of industrial applications,such as
The characteristics of methane-propane (CH4-C2H6) and Carbon dioxide (CO2) hydrate crystal growth on the gas/water interface were compared in pure water using optical microscope.We especially focused
