能源新秀——可燃冰

就在人们担心石化能源将被耗尽时,科学家们在海洋和冻土带发现了一种新型洁净能源——可燃烧的“冰”。其主要成分是甲烷与水分子(CH4·H2O),学名为“天然气水合物”,是天然气和水在一定的温度、压力条件下相互作用所形成的貌似冰状可以燃烧的固体,俗称可燃冰。据估算,世界上可燃冰所含有机碳的总资源量相当于全球已知煤、石油和天然气的2倍,可满足人类1000年的需求。这无疑给未来的能源需求带来了福音,引起了人们的广泛关注。可燃冰的发现纯属偶然。在上世纪30年代,为了输送天然气,铺设了输气管道,但工程人员发现,一些输气管经常奇怪地被…

Mantle processes during ocean formation：Petrologic records in peridotites from the Alpine－Apennine ophiolites

Mantle peridotites were early exposed at the sea-floor of the Jurassic Tethys derived from the subcontinental mantle of the Europe-Adria system. During continental rifting and oceanic spreading, these lithospheric peri-dotites were percolated via diffuse reactive porous flowby melt fractions produced by near-fractional melting of the upwelling asthenosphere. Ascending melts inter-acted with the lower lithosphere, dissolving pyroxenes and precipitating olivine, and crystallized at shallower levels in the mantle column causing melt impregnation.Subsequent focused porous flow formed replacive dunitechannels, cutting the impregnated oeridotites, which were conduits for upward migration of MORB-type liq-uids. Melt migration produced depletionlrefertilization and significant heating of the percolatedlimpregnated mantle, i.e the thermochemical erosion of the litho-sphere. Impregnated and thermally modified lithos-pheric mantle was cooled by conductive heat loss dur-ing progressive lithosphere thinning and was intrudeaby MORB magmas, which formed Mg-rich and Fe-richgabbroic dykes and bodies. Alpine-Apennine ophiolitic peridotites record the deep-seated migration of melts which changed their compositions and dynamics during the rift evolution. The thermochemical erosion of the lithospheric mantle by the ascending asthenospheric melts, which induces significant compositional and rhe-ological changes in the lower lithosphere, is a major process in the evolution of the continent-ocean transi-tion towards a slow spreading oceanic system.     

The Statistical Analysis of Migration of Strong Earthquakes-Taking the North China Region asan Example

The migration of strong earthquakes is an important research topic because the migration phenomena reflect partly the seismic mechanism and involve the prediction of tendency of seismic activity. Research on migration of strong earthquakes has mostly focused on finding the phenomena. Some attempts on getting regularity were comparatively subjective. This paper suggests that there should be indices of migration in earthquake dataset and the indexes should have statistical meaning if there is regularity in the migration of strong earthquakes. In this study, three derivative attributes of migration, i.e., migration orientation, migration distance and migration time interval, were statistically analyzed. Results in the North China region show that the migration of strong earthquakes has statistical meaning. There is a dominant migration orientation (W by S to E by N), a dominant distance ( ≤ 100kin and on the confines of 300 ～ 700km), and a dominant time interval ( ≤ la and on the confines of 3 - 4a). The results also show that the migration will differ slightly with different magnitude range or earthquake activity phase.     

热带海气耦合波动力学性质研究

本文利用简单海气耦合模式研究了热带大气和海洋不同波动之间的相互作用产生的耦合波及其稳定性等动力学性质,指出热带耦合系统中分别存在一类稳定的和不稳定的海气相互作用模态,其中不稳定模态的传播依赖于扰动的纬向尺度,即5000～10000km扰动表现为不稳定东传,大于此尺度的扰动发生不稳定西传,理论得出的缓慢不稳定东传波和观测事实甚为一致.最后本文指出热带海气耦合不稳定产生的基本条件是一种介质中的Kelvin波和另一种介质中的Rossby波的相互作用.
