美苏关系的新动向

美苏日内瓦第一轮军备控制谈判以没有解决任何一个问题而告结束。这样的结果并不使人感到意外。这次谈判的内容是太空武器、战略核武器和中程核武器,焦点是太空武器问题,即美国“星球大战”计划。太空武器正是美国的王牌,所以美国拚命坚持不放,苏联则坚决要反掉;而战略核武器中的陆基导弹则是苏联优势所在,所以苏联千方百计加以保护,美国则力图打掉它。     

新技术革命与军备竞赛、军备控制

科技革命的发展使战后军备竞赛产生了三次质的飞跃,同时新技术又可以制约军备竞赛,这也是军备控制延续40年未能中断的重要原因。技术还在发展,军备竞赛不仅将进入战略防御和宇宙空间,还将围绕进攻性战略核武器的机动化和精确化进行,另外还将出现新的竞赛领域。未来的威慑力量将不会是单一的核武器,而是由多种武器系统综合组成。但是,反过来,技术的发展又能抑制武器发展,它为军备控制提供朦胧的希望。     

西德的和平主义之风

近一时期,美苏围绕北约追补军备决议的争夺愈演愈烈,西欧一些国家出现了声势较大的反对部署美制新式中程导弹的和平主义浪潮。在荷兰,和平主义思潮渗入了某些主要政党,提出了西方中小国家单方面裁军以推动大国削减军备的主张,并使荷兰政府迟迟无法作出同意部署中程导弹的决定。在英国,争取核裁军的运动也有相当发展,工党“左”翼在反对核军备运动中充当了急先锋的角色。在北欧,反对引进核武器的浪潮此伏彼起,最近,5,000名“和平进军者”从哥本哈根步行1,200公里到达巴黎,沿途进行反核宣传。但是,发展最快、影响最大的还数西德的和平主义运动,它在西方国家引起了震惊,成了国际舆论关注的问题。鉴于西德是北约在欧洲的一个重要支柱,它在美苏争夺欧洲的角逐中具有举足轻重的作用,人们普遍关心:西德的     

美国在中东:拔钉子 除隐患 促变革

“谁是美国的下一个打击目标”?这是目前的热门话题。确实打完了塔利班打萨达姆,打完了萨达姆又接连说出伊朗和叙利亚的不是,总之美国的眼中钉太多了———歧视妇女的、教育落后的独裁的、无赖的、流氓的、极端宗教的、包庇恐怖主义的,再有就是胆敢发展核武器的。但凡事都有个轻重缓急,不同的国家也要区别对待,否则就乱了套了。那么,美国的任务书和日程表上究竟写了些什么呢?分门别类梳理一下,或许会让我们看得稍微明晰一些。冷战期间的中东,热战接连不断。为了扩张势力范围或维持势力均衡,美国和苏联都向中东投入了大量的军备和金钱,在70年…     

防止核扩散形势严峻

奥巴马政府对核扩散问题极端关注，他在2009年9月22日联大讲话中提到“一个和平与繁荣的未来”的四大要素，其中第一项就是“停止核武器的扩散，寻求一个没有核武器的世界”。为此．美国将完成新的《核态势评估报告》：美国呼吁各国从2010年1月开始谈判一项协议．以终止可用于核武器裂变的材料生产；美国和俄罗斯在去年12月就进一步削减战略核武器达成基本共识。     

军控议题在中美战略对话清单上位置前移

正近期,以美国为首的西方突然开始"热衷"与中国展开军控对话。先是美俄欧频繁喊话,企图拉中国加入美苏于冷战时期签署、现形同失效的《中导条约》。白宫发布的新闻稿显示,美国总统特朗普4月4日在白宫会见中共中央政治局委员、国务院副总理、中美全面经济对话中方牵头人刘鹤时提出,鉴于中美经贸谈判已经取得"令人满意"的结果,军费削减和军备控制(尤其是核武器)等议题应     

环球舆论

美曾境外部署核武器《原子科学家公报》最近销密的五角大楼文件表明,从1945年7月到1977年9月,美国在27个国家和地区部署了核武器。这些地点中包括18个主权国家。另一些地点是在美国控制的地区。从1954年到1965年,美国还把核武器上的非核部件存放在日本——尽管美国从来没有承认过。美国曾经计划,万一发生冲突,就用日本作为一个对中国或者对苏联发动该袭击的基地。70年代,为与中国改善关系华盛顿才把核武器撤出台湾。     

美国外交政策的宗教缘起

美国是当今世界宗教色彩最为浓厚的发达国家，具有悠久的宗教传统和众多的宗教信徒，宗教在美国社会生活中占有相当重要的地位，是影响美国内政外交的不容忽视的力量。基督教新教依然是美国的主流宗教，美国人的宗教信仰与其社会政治立场密切相关。美国外交的两大指导思想种族主义和扩张主义都有其宗教源头，分别对应基督教孤立主义和普世主义。宗教对美国外交实践的影响体现在战争、法律、组织建设等方面。研究美国外交政策中的宗教因素，能帮助我们更好地理解美国外交意图，把握美国外交走向，丰富对美国外交政策的全方位研究。     

世界缓和局势中潜藏着危机

缓和并不等于天下太平:固有的国际矛盾依然存在;美苏现存的核武器仍足以毁灭地球10次,它们淘汰旧的军备,发展新的武器;第二、第三世界某些国家也在不断加强军备,这些都是不容忽视的潜在危险。

Markedness and its Interpretation in Language Use

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.     

Lower Paleozoic oil relationships within Williston Basin, Canada

The Williston Basin is a significant petroleum province, containing oil production zones that include the Middle Cambrian to Lower Ordovician, Upper Ordovician, Middle Devonian, Upper Devonian and Mississippian and within the Jurassic and Cretaceous. The oils of the Williston Basin exhibit a wide range of geochemical characteristics defined as "oil families", although the geochemical signature of the Cambrian Deadwood Formation and Lower Ordovician Winnipeg reservoired oils does not match any "oil family". Despite their close stratigraphic proximity, it is evident that the oils of the Lower Palaeozoic within the Williston Basin are distinct. This suggests the presence of a new "oil family" within the Williston Basin. Diagnostic geochemical signatures occur in the gasoline range chromatograms, within saturate fraction gas chromatograms and biomarker fingerprints. However, some of the established criteria and cross-plots that are currently used to segregate oils into distinct genetic families within the basin do not always meet with success, particularly when applied to the Lower Palaeozoic oils of the Deadwood and Winnipeg Formation.     

An Analysis of Catherine＇s Character——Wuthering Heights

Wuthering Heights, Emily Bronte＇s only novel, was published in December of 1847 under the pseudonym Ellis Bell. The book did not gain immediate success, but it is now thought one of the finest novels in the English language. Catherine is the key character of this masterpiece, because everybody and everything center on her though she had a short life. We can understand this masterpiece better if we know Catherine well.     

Features of Women's language

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women＇s language from these perspectives： pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women＇s language, more attention should be paid to language use in social context. What＇s more, the linguistic phenomena in a speaking community can be understood more thoroughly.     

Characterization of Ordovician carbonate reservoirs, southeastern Saskatchewan, Canada

The discovery of the prolific Ordovician Red River reservoirs in 1995 in southeastern Saskatchewan was the catalyst for extensive exploration activity which resulted in the discovery of more than 15 new Red River pools. The best yields of Red River production to date have been from dolomite reservoirs. Understanding the processes of dolomitization is, therefore, crucial for the prediction of the connectivity, spatial distribution and heterogeneity of dolomite reservoirs.The Red River reservoirs in the Midale area consist of 3～4 thin dolomitized zones, with a total thickness of about 20 m, which occur at the top of the Yeoman Formation. Two types of replacement dolomite were recognized in the Red River reservoir: dolomitized burrow infills and dolomitized host matrix. The spatial distribution of dolomite suggests that burrowing organisms played an important role in facilitating the fluid flow in the backfilled sediments. This resulted in penecontemporaneous dolomitization of burrow infills by normal seawater. The dolomite in the host matrix is interpreted as having occurred at shallow burial by evaporitic seawater during precipitation of Lake Almar anhydrite that immediately overlies the Yeoman Formation. However, the low δ18O values of dolomited burrow infills (-5.9‰～ -7.8‰, PDB) and matrix dolomites (-6.6‰～ -8.1‰, avg. -7.4‰ PDB) compared to the estimated values for the late Ordovician marine dolomite could be attributed to modification and alteration of dolomite at higher temperatures during deeper burial, which could also be responsible for its 87Sr/86Sr ratios (0.7084～0.7088) that are higher than suggested for the late Ordovician seawaters (0.7078～0.7080). The trace amounts of saddle dolomite cement in the Red River carbonates are probably related to "cannibalization" of earlier replacement dolomite during the chemical compaction.

橡胶颗粒沥青混合料低温抗裂性试验研究

以AC-13级配为基础,将橡胶颗粒代替部分集料掺入混合料中,以低温弯曲试验为评价方法对不同橡胶颗粒掺量下沥青混合料的低温抗裂性进行研究,并引入应变能密度值对混合料的低温抗裂性进行综合评价.试验结果表明:橡胶颗粒沥青混合料试件的破坏微应变均超过2 300,满足冬寒区的技术指标;无论是否掺加橡胶颗粒,随着温度的下降,沥青混合料破坏时的最大弯拉强度增大,弯拉应变降低,劲度模量增大;弯曲应变能密度在胶粒掺量为1%左右时具有较大的弯曲应变能密度值,此时橡胶颗粒沥青混合料具有较好的低温抗裂性.     

低渗透非均质砂岩油藏启动压力梯度研究

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。     

Quantitative trait loci （QTLs） for quality traits related to protein and starch in wheat

Quality traits in wheat （Triticum aestirum L.） were studied by quantitative trait locus （QTL） analysis in a recombinant inbred line （RIL） population, a set of 131 lines derived from Chuan 35050 × Shannong 483 cross （ChSh）. Grains from RILs were assayed for 21 quality traits related to protein and starch. A total of 35 putative QTLs for 19 traits with a single QTL explaining 7.99-40.52% of phenotypic variations were detected on 10 chromosomes, 1D, 2A, 2D, 3B, 3D, 5A, 6A, 6B, 6D, and 7B. The additive effects of 30 QTLs were positive, contributed by Chuan 35050, the remaining 5 QTLs were negative with the additive effect contributed by Shannong 483. For protein traits, 15 QTLs were obtained and most of them were located on chromosomes 1 D, 3B and 6D, while 20 QTLs for starch traits were detected and most of them were located on chromosomes 3D, 6B and 7B. Only 7 QTLs for protein and starch traits were co-located in three regions on chromosomes 1D, 2A and 2D. These protein and starch trait QTLs showed a distinct distribution pattern in certain regions and chromosomes. Twenty-two QTLs were clustered in 6 regions of 5 chromosomes. Two QTL clusters for protein traits were located on chromosomes 1D and 3B, respectively, three clusters for starch traits on chromosomes 3D, 6B and 7B, and one cluster including protein and starch traits on chromosome 1D.     

On Tragic Consciousness In The Works By Ernest Hemingway

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.
