末次冰期以来东海内陆架沉积反映的海平面变化

对东海内陆架泥质沉积区MD06-3042孔(27°05.4′N,121°24.1′E,水深62m,岩芯长34.1m)样品进行了高分辨率的粒度分析和14C年代测试,重建了末次冰期以来东海内陆架区的海平面及沉积环境的变化.14.0ka左右,海平面已经到达现今海平面下62m等深线的位置,大量沉积物在此沉积.13.0~4.2ka之间,受海流等多种因素影响,少量沉积物在此沉积.4.2~3.2ka之间,现代东海内陆架的泥质沉积主体在该岩芯附近快速堆积.东海内陆架的泥质沉积体由北向南,由内向外逐渐形成,具有阶段性.     

An virtual numerical experiment to understand the impacts of recovering natural vegetation on the summer climate and environmental conditions in East Asia

By applying a regional integrated environmental model system (RIEMS), a virtual numerical experiment is implemented to study the impacts of recovering natural vegetation on the regional climate and environmental conditions. The results show that recovering the natural vegetation in large scale could have significant influence on summer climate in East Asia. Not only would it be able to change the surface climate, but also to modify to certain extent the intensity of monsoon circulation. Although this is a virtual experiment at an extremely ideal condition, the implication of the simulating results is that the on-going nation-wide activities to recover the crop land for forest and pasture must be managed according to the local natural climate, hydrological and soil conditions. Only under such a condition, would the recovering of natural vegetation bring about significant climate and environmental benefits at regional scale.     

文明来自东方——就宗教和神话谈近东文明对西方文明的影响

西方文明兴起较晚，当希腊、罗马文明兴起之时，近东已有上千年的文明。因而西方文明不可避免地受到古老近东文明——苏关尔、巴比伦、埃及、波斯诸文明的影响。尤其是近东各民族的宗教和神话对希腊、罗马乃至基督教的影响甚为久远，经由他们的融合吸收、加工提炼，最后成为今日西方文明的一部分。     

Weathering Signals of Millennial-Scale Oscillations of the East-Asian Summer Monsoon over the Last 220 ka

This study generated a high-resolution paleoweathering record of the loess-soil sequence from the central Loess Plateau covering the last 220 ka using the ratio between the CBD (citrate-bicarbonate-dithionite) extractable free Fe_2O_3 (Fed) and total Fe_2O_3 (Fet). The new proxy shows a series of millennial oscillations, which are not necessarily documented by magnetic susceptibility from the same site. Because chemical weathering in the region depends mainly upon summer precipitation and temperature, we interpret these changes to be a result of millennial-scale variations in the strength of the East-Asian summer monsoon. Over the last glacial period, there is general agreement between the loess weathering record and the GRIP ice δ~(18)O record. The first suggests a rather stable summer monsoon pattern during the Last Interglacial period (marine δ~(18)O stage 5e). Large amplitude millennial oscillations of the summer monsoon seem to be particularly characteristic of the last glacial period whereas the fluctuations for the older periods are smoother.     

民间对日索赔与东亚和谐

亚洲民间对日索赔,是亚洲各国日本侵略战争的受害者及其遗属,以法律为武器、通过诉讼的方式要求加害方承担战争责任并进行谢罪赔偿的正义行动。日本政府顽固地拒绝向受害者进行道歉和赔偿,不仅与其追求的"正常国家"的目标背道而驰,还把其降为政治上的二流国家。在对日索赔过程中,亚洲正义和友好人士的积极合作,已经成为民间外交的重要组成部分。日本只有妥善解决战争受害者的赔偿问题,与受害民族达成谅解与和解,才能促进东亚和谐社会的早日形成。     

2017年国际篮联亚洲杯中国队与对手攻防实力比较研究

采用文献资料法、录像观察法、数理统计法和秩和比综合评价法等,对2017年男篮亚洲杯中国队与四强球队的攻防技术指标进行比较分析,结果表明:在进攻方面,中国男篮与澳大利亚男篮在总投中数、 2分球命中数、助攻和得分指标上差异具有统计学意义,与韩国男篮在助攻指标上差异具有统计学意义;在防守方面,中国男篮与伊朗男篮在防守篮板上差异具有统计学意义.建议进攻端提高球员身体素质,增强身体对抗,加强投篮训练,提高罚球命中数,增强争抢前后场篮板意识,加强整体配合,丰富技战术手段;防守端提高抢断和盖帽预判能力,增强团队整体防守强度,端正态度,积极防守,提升脚步移动速度,及时做到补防、协防和换防,减少犯规次数.     

黑龙江省气候成因

黑龙江省的气候,是在众多的相关地理要素共同作用下形成的,本文从纬度位置、季风环流和地形因素3个主要方面进行了分析．而且,在分析其对气候形成的影响时,涉及的气候要素主要是气温和降水．纬度位置对气候的影响,主要体现在热量条件上．季风环流从气温和降水两个方面影响黑龙江省气候．地形因素干扰、破坏着上述两种因素所形成的规律,在一定程度上隔断了气候要素经向和纬向的空间地带性分布,从而使气候变得更为复杂。

东海低氧区浮游植物群落的昼夜垂直变化

根据2011年5月航次(春季)、8月航次(夏季)和11月航次(秋季)在东海低氧区共6个站位进行的昼夜连续观测所获浮游植物水样,用Uterm?hl方法分析了浮游植物群落的昼夜垂直变化.春季共检出浮游植物99种,优势种为具齿原甲藻(Prorocentrum dentatum)、具槽帕拉藻(Paralia sulcata)和骨条藻(Skeletonema sp.);夏季检出93种,优势种为劳氏角毛藻(Chaetoceros lauderi)、铁氏束毛藻(Trichodesmium thiebautii)、具槽帕拉藻;秋季检出78种,优势种为具槽帕拉藻、骨条藻和圆筛藻(Coscinodiscus sp.).春季细胞丰度明显高于夏、秋季;春、夏季细胞丰度随水深增加逐渐降低,秋季细胞丰度分布较均匀;春、夏季上层水体浮游植物丰度昼夜变化较剧烈,下层水体相对平缓;秋季D3站位表层和J1站位底层细胞丰度昼夜变化较剧烈,其余水层细胞丰度昼夜波动不明显.春季D2站位20,m水层及夏季O11站位各水层优势种组成存在明显的昼夜变化,其余各水层浮游植物群集相对稳定.调查站位各水层间浮游植物群集结构差异明显.
