Sunda盆地(印尼)古近系Zelda段(扇)三角洲沉积特征

前人认为Sunda盆地古近系Talang Akar组Zelda段主要为河流沉.本文通过对岩心的岩性序列与沉积构造、测井曲线形态组合与地震反射特征的系统研究,认为古近系渐新统Zelda段主要为三角洲和扇三角洲沉积体系,在Zelda段沉积早期还发育代表盆地快速下沉阶段的近岸水下扇、滨浅湖、深湖以及浊积扇沉积.详细论述了Zelda段三角洲及扇三角洲的沉积特征和平面分布规律.     

Cryptic and non-cryptic diversity in New Guinea ground snakes of the genus Stegonotus Duméril,Bibron and Duméril, 1854: a description of four new species (Squamata: Colubridae)

ABSTRACT

The island of New Guinea has been identified as biologically megadiverse but many taxa are still poorly known. This is especially the case for many of the island’s snakes, which by their very nature can be difficult to collect and study. Here we examine the phylogenetic and phylogeographic structure of a poorly studied snake genus, Stegonotus, focusing on the species of New Guinea; until now, Stegonotus has never been examined using modern phylogenetic methods. Using molecular data from 49 individuals representing eight of the ten described species, and including all New Guinea taxa, we estimate a multilocus phylogeny and examine population structure to help identify undescribed taxa. We use morphological data from the corresponding museum vouchered specimens (where available) and also examine additional specimens for taxa not included in the molecular data set to determine morphological differences among putative taxa. We find molecular evidence for four new species of Stegonotus, both morphologically obvious and cryptic, and describe them herein. The recognition of these four species indicates that Stegonotus diversity has been previously underestimated and also suggests that there are likely additional undescribed taxa within the genus. These four taxa increase the number of described species by 40% and further confirm New Guinea as the centre of diversity for the genus.

哈比比时期印尼政府改变对东帝汶政策原因解析

亚洲金融危机使苏哈托政府垮台,哈比比在军方领导人的支持下继任总统。一些国家和非政府组织抓住机会在东帝汶问题上对印尼施压;东帝汶人民也加紧反抗,并适时改变斗争策略。为了赢得国际援助,并增加自身政治资本,哈比比不得不改变对东帝汶的政策,最终促成东帝汶的独立。     

印尼M、N凝析气田产能描述

结合M与N凝析气田的地质特征与流体特点,分析二项式产能方程异常的原因,并进行校正,有效建立了24次产能测试中的21个产能方程,计算无阻流量介于（3~192）×104m3/d,大部分气井为中、高产气井。建立了测井解释渗透率与试井解释渗透率之间、试井地层系数与无阻流量之间、合理产能与无阻流量之间的关系;结合最小携液量图版,确定技术上合理的产能。实际应用时可以根据生产的需要调整合理产量,为方案设计、生产规划提供技术依据。     

二元碱度对印尼钒钛矿烧结过程及烧结矿质量的影响

以典型钢铁企业矿石资源为基础,进行不同碱度条件下配加印尼钒钛矿的烧结试验,考察了二元碱度(R=m(Ca O)/m(Si O2))对该矿烧结过程及烧结矿质量的影响.研究表明:当碱度R由1.4逐渐增至2.3时,烧结有效利用系数由1.63 t/(m2·h)降至1.44 t/(m2·h),烧结矿成品率由78.5%降至75.3%;同时,垂直烧结速度有所上升;烧结矿中w(Fe O)不断下降;转鼓指数先下降而后逐渐回升,并在R=1.7时出现最小值.随着碱度的逐渐增加,低温还原粉化性能和还原性逐渐改善,这有利于高炉上部透气性的改善和间接还原的发展.     

印尼中立主义外交初探

中立主义是冷战期间印尼外交政策的基本指导思想。印尼中立外交的特点是长期中立,国内政治体制的变动并没有动摇其中立主义的外交基石。中立主义外交既是印尼自身的地缘位置和政治文化影响的结果,又与印尼的国内政治需求存在着密切的联系。     

美国在印尼非殖民化过程中的政策变化及作用分析

按照战时美国关于印尼的计划，荷兰将有序地恢复其殖民统治，并指导印尼渐进地获得独立。但是，战后印尼民族主义者没有遵循美国所设想的非殖民化道路，而是建立起一个稳定的共和国政权。在荷兰与印尼冲突开始后，美国政府起初希望采取中立政策，以避开尴尬的非殖民化问题。但随着印尼局势的日益恶化，尤其是“茉莉芬事件”后，印尼共和国的反共倾向符合美国在东南亚的利益，而荷兰顽固的殖民政策已经威胁到美国战后外交政策目标的实现，美国最终选择了支持印尼走向非殖民化之路。     

战后印尼华文教育发展的潜在动力——论华人文化认同对印尼华文教育的促进

印度尼西亚是东南亚华人最主要的聚居区之一,其华人教育有着较早的历史和良好的发展基础。但长期以来,由于遭受各种因素的影响,华文教育在印度尼西亚的发展历经曲折和坎坷。印度尼西亚历届政府的教育政策、中国国际地位的高低以及华人的文化认同都影响着印度尼西亚华文教育的发展,但从根本上说,华人对中华文化的认同才是华文教育产生和发展的根本原因,是支撑华文教育发展的重要支柱。
