一次江淮大暴雨过程中尺度系统结构分析

本文应用观测资料和中尺度数值模拟结果对1999年6月23日发生在江淮地区一次梅雨锋暴雨过程进行研究，揭示了影响这次暴雨过程的物理条件、云团的演变特征及与中尺度系统的关系，分析表明，在暴雨生成和发展过程中，多个中尺度云团在相继生成和移动发展，暴雨中心是几个发展较强的中尺度对流云团造成的，西南风低空急流为暴雨提供了水汽输送，并且通过强垂直运动向对流层中上层输送水汽，这次暴雨与中尺度系统发生发展有直接关系，西南涡分裂出一系列的小涡旋，这些小涡旋边向东移边减弱，并且同时在地面上引发小低压，这些中尺度低压增强低空水平辐合，成为触发不稳定能量的机制，低空急流中心与雨区相互对应，且急流风速增强，风速水平切变梯度增大的过程对应着强降水过程。

“一带一路”倡议的理论论述——从新自由主义全球化到包容性全球化（英文）

An international consensus is emerging around the Belt and Road Initiative(BRI) proposed by the Chinese government, with a growing number of countries seeing it as a way of jointly exploring new international economic governance mechanisms. Meanwhile, with the crisis of neo-liberalism, economic globalization has arrived at a crossroad. In particular, incessant voices speak out against globalization, making the quest for a new way of promoting global development a major challenge. In this context, more and more political elites and scholars consider that the BRI opens up a possible new globalization path, amongst which inclusive globalization warrants exploration. On the basis of a brief analysis of the course and mechanism of global economic expansion and the limitations of neo-liberal globalization, along with the putting into practice of the BRI, this paper outlines some of the core features of inclusive globalization, i.e., inclusive growth with effective and efficient government regulation; inclusive infrastructure development; inclusive development paths chosen nationally that suit national conditions; inclusive participation; and cultural inclusiveness. Although these features are not sufficient to characterize fully inclusive globalization, they do identify some directions for future research, and provide elements of a discursive construction of the BRI.

ON THE SOURCE AND GENESIS OF THE MUD IN THE CENTRAL AREA OF THE SOUTH YELLOW SEA

Investigations and studies for years all demonstrated that there is a patch of fine-grained mud in the central area of the South Yellow Sea. However, scientists have different opinions on its material source, genesis, and sedimentation intensity. Some believe that the materials come from the Huanghe River, some think that the mud area represents the depocentre of the South Yellow Sea, and some consider it as "relict mud ". The authors ' geochemical study reveals that the mud is multi-sourced, yet the material supply is not ample, and that a little amount of fine-grained suspended materials deposited slowly under the dynamic action of a cyclonic gyre formed the modern muddy sediment, which is named "multi-source modern mud ".     

贵州织金磷矿稀土富集机制、赋存状态及可利用性

巨量的海相沉积磷矿不仅是磷的主要来源,而且还因其中大部分富含稀土元素而成为潜在的稀土资源。为更好地理解这类稀土的成矿规律、赋存状态和开发利用前景,本文利用XRD、SEM、LA-ICP-MS和TEM等分析手段,对贵州织金富稀土磷块岩进行研究。结果表明,稀土元素主要通过扩散作用从海水及孔隙水富集于纳米级磷灰石中。低沉积速率和纳米级磷灰石较大的比表面积均有利于稀土成矿;磷矿后期经历了低温还原性富F热液流体改造,改变了稀土元素的分布特征和配分模式,但这并非稀土富集主要原因;TEM分析显示,稀土元素主要以类质同象形式赋存于磷灰石晶格之中;稀土元素在磷灰石中晶格尺度赋存特点决定了只能对磷灰石进行分解破坏的提取方式。使用酸浸法将稀土元素作为伴生资源提取,是一种有效途径。     

A STUDY ON ELEMENT-STRATIGRAPHY OF OKINAWA TROUGH

Regular distribution patterns of elements Ca, Sr, K, Na, Mg, Fe, Mn, Ti, Cu, Co, Ni,Zn, Ph, Cr, Rb, Ba, Cd, and U in Late Quaternary strata have been studied in detail. The regional variation patterns of elements in these strata are similar to those in recent surface sediments, showing that the sedimentary environment has been relatively stable since Late Quaternary. Element distribution changes with the variations of lithologtcal characters. Contents of Ca and Sr increase in coarse sediments, while those of other elements decrease. Na content increases in the pumice layer, Mn content tends to increase sharply towards the surface layer. Ca content decreases sharply in strata where water depth is more than 2,000m.The strata can be divided based on the distribution curves of element assemblages. The variations in contents of most elements in Holocene Series are smaller than those in Late Pleistocene Series, which might be related to the factors of glacial and interglacial changes, sea level fluctuations a     

全球电子信息产业贸易网络演化特征研究

随着全球经济一体化的不断深入,全球各产业贸易逐渐呈网络模式发展。作为经济发展的主要驱动力之一,电子信息产业对促进社会发展、优化产业结构有重要影响。本文利用WTO统计数据库1993年~2012年的电子信息产业贸易数据,通过贸易区位熵测算国家间贸易集聚程度,从而刻画全球电子信息产业贸易网络及其演化特征,在识别主要影响因素的基础上探讨了影响机理。研究认为,全球电子信息产业贸易网络自20世纪90年代至今经历了由"单极化"向"多极化"的演变历程,子产业贸易网络遵循"发达国家(地区)—发展中国家(地区)"的发展模式,呈现"出口集聚、进口分散"的特点。处于产业链低端、中端和高端的产品贸易网络存在较大差异,低端产品基本实现了向发展中国家的全面转移,而高端产业目前仍以发达国家为主导,处于演化初期。研究表明,影响贸易网络演化的因素分为政策环境、经济水平、生产要素市场、生产技术水平等方面,经济全球化推动全球电子信息贸易网络形成,区域经济集团化带动贸易活动向经济一体化组织的成员国集中,廉价生产要素为发展中国家贸易网络发展提供优势,高生产水平国家保留价值链高端产业贸易网络。此外,政策要素同样为重要影响因素,我国电子信息产业政策对自身贸易网络扩张有引导性作用。
