论翻译工作中译者与读者的统一

翻译是一个复杂的语码转换过程。此过程会牵涉到译者和读者间的相互关系，他们之间的关系是统一的，缺一不可的。正确处理好这两者的关系，对于译事至关重要，还可以解决翻译中的许多问题。另外，翻译过程中，译者地位的重要性较突出，译者应加强自身素质的培养，以期译出更好、更受读者欢迎的文本。     

存在自干扰码时的短周期伪码截获技术

针对伪码截获这一无线电侦察和导航战中的难题,从模式识别的角度研究存在自干扰码时的伪码截获问题。通过对干扰码的载波频率、相位等参数的估计和补偿,将自干扰码下的伪码截获问题转换为模式识别问题。结合伪码的周期性,采用二进制积累的方法大大降低了判决前所要求的信噪比,使得对扩频信号直接解调以截获伪码成为可能,改变了过去依靠大口径天线提高信噪比的方法。     

用好12种课堂用语

教师的天职是讲课,讲课就离不开语言.课堂语言有自身的特点,与其它语言相比,主要有四个不同:一是不同于书面语.书面语是用眼睛看的,它的载体是文字;课堂语是用耳朵听的,它的外壳是语音.二是不同于日常语.日常语随意性很大;课堂语比较规范,有时还要刻意琢磨.三是不同于广播语.广播员读别人的文章;课堂语是教员深化和讲说自己的稿子.四是不同于表演语.表演语是演员的台词.演员有一个“进入角色”的问题,这就出现了两个“我”,一个是演员自己(真我),一个是角色(假我);课堂语是由教师表达,表达的是自己思考的问题,只有一个我,那就是教师自己,是真我.既然课堂语有其特定的含义和自身要求,那么究竟怎样把握课堂语呢?我的体会是要用好12种课堂语言.     

书面语在国际中文教育中的应用

书面词汇是现代汉语书面语表达的源泉，书面语词汇的正确使用是汉语学习者掌握书面语表达流畅能力的基础。书面语和口语二者属于不同语体，二者之间具有差异，主要包括语法不同、社会功能不同、表达方式不同、词汇系统使用不同、载体不同。从深度国际化角度而言，书面语教学、书面语能力的建构更具有重要意义。促进书面语在国际中文教育中的应用，要积极开展线上教学，教材大纲是核心环节，教师落实好书面语教学，学生要发挥好主体建构能力。     

一种改进的多相码信号参数估计法

目前,对由频率导出的一类多相码脉压雷达信号(Frank码和P1 ～ P4码)进行参数估计是电子对抗侦察技术中的难点之一.针对此问题,提出一种基于改进的分数阶傅里叶变换(FrFT)的多相码信号参数估计方法.该法利用积分二次相位函数将FrFT的二维搜索转换为2次一维搜索,较大减少了计算量.仿真表明,该法能在较小的计算量下达到与RWT和RAT法相当的估计精度.

Terrorism,insurgency, kidnapping,and security in Africa's energy sector

Energy continues to serve as the bedrock of modern economies and the main driver of modern society. For Africa, the production and supply of energy resources such as crude oil, natural gas, uranium, coal, biomass, biofuels and other renewables are an important source of employment, rents, taxes, royalties and profits. This sector brings in several tens of billions of dollars of revenue annually. The production and delivery of such resources, however, depend on critical infrastructures such as pipelines, refineries, processing plants, terminals, rigs, electrical energy pylons, substations, pump stations, vessels, and tankers. These infrastructures have been attacked by terrorists, insurgents, vandals and saboteurs, all of whom see them as targets against which to register their grievances and extract concessions from the state. This paper is a chronological account of some of the documented incidents of terrorism, insurgency, kidnapping, destruction, sabotage, and human casualties suffered in the oil and gas sectors in Africa between 1999 and 2012. It is based on data extracted from the databases of the RAND Database of World Terrorism Incidents and the University of Maryland's Global Terrorism Database (GTD).     

Tacit support for terrorism: The rapprochement between the USSR and Palestinian guerrilla organizations following the 1967 war

This article demonstrates the inconsistent and wavering Soviet attitude towards national liberation movements in general and the Palestinian organizations in particular. Until the late 1960s, the Soviets viewed these organizations with suspicion, hesitating to engage in political dialogue with them. However, in the 1970s, political and military events in the region, as well as modifications in the Kremlin's Cold War strategies, led to a general shift towards the Middle East in Soviet foreign policy. Soviet leaders showed increased willingness to provide certain Palestinian organizations with arms with which to conduct terrorist activities against Israeli, pro-Israeli, Jewish and Western targets. The article explores the complex relations between Palestinian organizations and the USSR in the field of international terror. The study also exposes and analyzes the nature and content of Soviet–Palestinian arms dialogues and transactions. It provides clear evidence that Soviet policymakers and other luminaries were fully informed of, and sometimes directly involved in, these transactions and dialogues at the highest levels.

Country survey XVI the defence sector in the economy of a declining superpower: Soviet Union and Russia, 1965-2001

The Soviet Union was able to develop a large military-industrial complex and become the world's second superpower despite deficiencies in its centrally planned economy because defence was given high priority status and special planning, rationing and administrative mechanisms were used to attain national security objectives. However, in the period 1976-85 the effectiveness of priority protection diminished and defence institutions experienced more of the problems typical of the shortage economic system. The heavy defence burden also created growing difficulties for the civilian economy. The attempts by the Gorbachev government to reform the defence sector and improve defence-economic relationships during perestroika (1985-91) uniformly failed. For most of the transition period, the Russian military-industrial complex has been adversely affected by its low priority status, cuts in defence spending, instability of the hybrid politico-economic system, and negative growth of the economy. The armed forces and defence industry have been reduced in size and their outputs of military services and equipment have fallen to low levels. Nevertheless, the Russian armed forces still have over one million troops, significant stocks of sophisticated conventional weapons, and a large nuclear arsenal. The government of President Putin has raised the priority of the defence sector, increased real defence spending, and adopted ambitious plans to revive Russian military power. It is likely, though, that tight resource constraints will hamper efforts to reform the armed forces and to upgrade weapons. By 2010 Russia will be an important, but not dominant, military power in Eurasia.     

Helping hands: civil–military cooperation and Italy's military operation abroad

In the Post-Bipolar Era the growing complexity of the military operations requires a new approach for the resolution of international crises. Since the end of the Cold War, peace support operations (PSO) have become the mainstay and principal occupation of most Western armies. At the same time, Italy has been one of the most important actors in such an area. The article focuses on the cooperation between military and civil components (a process called CIMIC) as a key variable in the Italian PSOs. We will analyse in detail the main lessons learned from past military interventions as well as the general context in which new tendencies are taking place. The maintaining of a minimum security frame becomes essential to fulfil activities ‘collateral’ to the mission: reconstructing services and infrastructure, food distribution, water and medication, law and order, de-mining, training of local forces, and supporting local institutions. These are the main tasks to obtain thrust and support from the population.     

Formation and impact-induced separation of tandem EFPs

The formation and separation behaviors of tandem EFPs are studied by the combination of experiments and simulations. The results show that different formation and separation processes can be obtained by adjusting the double-layer liners, and simulations agree with experiments well. Then, the interaction process between the two liners is discussed in details, and the formation and separation mechanism are revealed. It can be found that there are four phases in the formation and separation processes, including impact phase, propulsion phase, slide phase and free flight phase. During the impact phase, the velocities of two liners rise in turns with kinetic energy exchange. In the propulsion phase, the axial impact becomes insignificant, but the radial interaction between two liners influences the appearance of tandem EFPs. Meanwhile, it should be mentioned that the inner surface of foregoing EFP remains to be in contact with the outer surface of following EFP in the propulsion phase, and the following one would continue to push the foregoing one for about 10μ to 20 μs, causing the velocities of following and foregoing EFPs gradually decreasing and increasing respectively. In the slide phase, an obvious relative movement occurs between the two EFPs, and there would be barely kinetic energy exchange. Then, the two EFPs separate gradually and get into the phase of free flight. Generally, if the outer and inner liners have the same thickness, the outer copper-inner copper liners form two long EFPs, the outer copper-inner steel liners become a foregoing short steel EFP and a following long copper EFP, and the outer steel-inner copper liners produce a foregoing long copper EFP and a following conical steel EFP. In addition, thickness match also has an important impact on formation appearance and separation process for both outer copper-inner copper liners and outer steel-inner copper liners. With the thickness ratio of outer liner to inner liner decreasing, the length and length-diameter ratio of both foregoing and following EFPs increase gradually.

Bourdieu’s capital and insurgent group resilience:a field-theoretic approach to the polisario front

The conflict between the rebel group, the Polisario Front, and the Kingdom of Morocco is nearing its 43rd year. Though under-reported, the conflict itself garners attention for the resilience – some would say tenacity – of the ethnically Sahrawi Polisario Front. Despite shifting regional and international politics and the nearly 150,000 Sahrawi refugees waiting in nearby Algerian camps, the rebel group has survived. What explains its resilience? This article uses Bourdieu’s ‘forms of capital’ to understand the Polisario Front’s persistence. Based on field research in Algeria, Western Sahara, and the United States, it finds that social, cultural, symbolic, and economic capital may provide an explanation.     

基于区块链的地学大数据管理

随着地理观测技术、计算机网络和地理信息系统、社会调查统计的迅速发展,具有空间位置的自然环境数据正在急剧增长,上升到大数据级别。而传统的数据库已经无法满足现有地学大数据的规模和增长速度。在资源访问方面,人们更加担心数据安全与隐私保护问题。由于数据交易的双方和交易中介都是互不信任的,这显然不利于数据的共享与流通,将阻碍地学大数据产业的发展。常用地学数据管理系统主要由单一机构进行维护管理,在多方用户参与的情形下,由于无法信任数据库中的数据,每一方用户都需要一个专用数据库,这样不同数据库之间数据的差异将产生繁琐的争议。区块链的到来却给这一问题的解决带来了希望,区块链技术实现了不完全可信网络环境中的可信数据管理,具有去中心化、防篡改、不可抵赖、完整性等特性,从而为解决目前依靠中心或第三方机构存在的高成本低效率和信息安全问题提供了切实的方法。本文从区块链的共识机制、智能合约、身份验证、数据溯源等方面进行阐述,并重点分析区块链如何解决流通和共享数据的问题,让地学大数据真正得以广泛应用。
