| 1 | Use of acoustic intensity measurements in underwater acoustics (Modern state and prospects)显示文摘This paper discusses scalar and vector characteristics of underwater ambient noise which were explored by the authors and their colleagues in different regions of the Earth Ocean.The measurements presented were performed in 6 Hz - 1000 Hz band, at depths up to 1000 m and wind speeds less than 15 m/s. The following questions are addressed: ratio between edsotropic (coherent) and isotropic (diffusive) parts of ambient noise; noise energy transport and its cotmection with surface waves propagation direction; noise energy flow cancenation by opposite energy flow of signal; signal-to-noise ratio for combined receiver in dynamic noise field. It follows from the results presellted, that further development of underwater intensity measurements opens new opportunities for investigations in the fields of underwater acoustics and oceanology. | Vladimir A.

| 4 | Structure of the Intermetallic Compound Ni_3Al Synthesized under Compression of the Powder Mixture of Pure Elements Part Ⅰ: Phase Composition and Microstructure of Main Phase显示文摘It was shown by TEM and X-ray analysis that there are four types of grains of the main Ni3Al phase in the structure of the intermetallic obtained by the self-propagation high temperature method (SHS). Every type of grains has its own domain and dislocation structure. There are mono- and polydomains with and without dislocations. The grains of the main phase of monoand polydomains without dislocations and polydomains with dislocations were formed by diffusion in the solid phase. In these conditions NiAl3 phase is located on the grain boundary of the main phase. The Ni2Al3 phase is located at the triple joints of the main phase. | M. V.

| 5 | SUPERPLASTICITY AND SOLID STATE BONDING OF TITANIUM ALLOYS显示文摘Experimental results related to solid state weldability of superplastic titanium alloys are presented. A correlation between superplastic flow and enhanced solid state weldability was established. It has been experimentally shown that a drop in the lower superplastic flow temperature with decreasing mean grain size provides an opportunity to decrease the temperature at whicmethods for titanium alloys. | R.

| 6 | Influence of Al Composition on the Microstructure of B Alloyed Ni_3Al Synthesized under Compression显示文摘It was shown by TEM and X-ray analysis that Ni3Al is the main phase of the intermetallic synthesized under compression from the powder mixture of Ni with Al alloyed by B. The Ni3B is a secondary phase. The value of the lattice parameter of the intermetallic Ni3Al with and without B increases when the concentration of Al increases. The increase in Al concentration from 23.5 to 25.0 in the initial powder mixture leads to decreasing the solubility of B in the Ni3Al phase. | M.V.Fedorischeva, O.B.Perevalova and V.E.Ovcharenko Institute of Strength Physics and Materials Science, Russian Academy of Sciences, Siberian Branch 634021, Tomsk, Russia B.

| 7 | “Color Revolutions” and Beyond显示文摘“Color revolutions” (or “orange revolutions”) broke out in some of the Commonwealth of Independent States in the past couple of years, reminiscent of the drama of disintegration of the former Soviet bloc at the turn of the 1990s. Why those upheavals came hot on the heels of the Soviet collapses merely a dozen or so years ago? Are we expecting more domino effects down the road? What geographical repercussions will they spark? A panel discussion was held on the topic and their views published in the journal. | Dr. Ji Zhiye is Research Professor and Assistant President of China Institutes of Contemporary International Relations (CICIR), and Director of the Institute of Russian Studies concurrently.

| 8 | 经由和谐发展走向地区稳定:新世界格局中的俄罗斯与中国——“瓦尔代”国际辩论俱乐部俄中分组讨论用提纲显示文摘国际格局未来10-20年的核心问题,俄方认为是美国和西方的整体性衰落和中国崛起之间的矛盾;中方倾向于认为,未来相当长时期内大国之间合作维护全球和平与发展的趋势有可能超出其竞争与冲突的一面。中国将继续保持谦虚、谨慎的态度,提升学习与创新能力,承担更多的国际责任。俄方断定,在西方衰落和中国崛起的大背景下,各方围绕俄罗斯的争夺似正日益明显,这既是基于俄的资源和欧亚大陆的重要战略地位,更是由于俄可能成为左右力量平衡的'最后一根稻草'。中方学者认为,俄罗斯重新崛起的基础已经奠定。与中国相比,俄在当代国际体系转型中可能会处于一个相对较为有利的地位。关于中俄双边关系,俄方集中关注两国经济贸易合作,认为主要存在经济关系远远落后于政治关系以及贸易结构原料化等问题。中方学者认为,中俄关系的中长期前景的主要挑战不在于政治关系和经济关系的不对称,而在于双方能否适应彼此关系的重新定位,能否建立起真正意义上的相互信任。俄方主张亚太地区必须建立新的地区安全和发展模式,以解决中美关系对抗性的潜在上升这一核心问题。中方主张,俄罗斯可以改变目前在政治和经济上参与亚太事务明显不足的局面。中俄两国有必要主动提出并推动亚太地区的国际议程设定,担负起'服务型大国'的责任,给地区发展和繁荣带来更多的公共产品。关于中亚地区局势和上海合作组织,两国学者都认为中亚地区不是俄中两国竞争的领域,或是俄中两国发生冲突的地区。 | Center for russian studies of ECNU & Council on foreign and defense policy | 2011 | 俄罗斯研究2011,,4: | 2 |
| 9 | Numerical Solution of Constrained Mechanical System Motions Equations and Inverse Problems of Dynamics显示文摘In this paper the method of design of kinematical and dynamical equations of mechanical systems, applied to numerical ealization, is proposed. The corresponding difference equations, which are obtained, give a guarantee of computations with a given precision. The equations of programmed constraints and those of constraint perturbations are defined. The stability of the programmed manifold for numerical solutions of the kinematical and dynamical equations is obtained by corresponding construction of the constraint perturbation equations. The dynamical equations of system with programmed constraints are set up in the form of Lagrange’s equations in generalized coordinates. Certain inverse problems of rigid body dynamics are examined. | R.G. Muharliamov (Russian Peoples’ Friendship University, 117198, Moscow, Mikluho Maklaya,6,Russia.) | 2001 | 应用数学2001,14,2: | 2 |

Physica and mathematical models describing such processes in CO2, origind software hare been developed.The re- sults of physical simulation and mathemaical modelling permit to determine the influence of energetic parameters of the process on the condition of the 'power source-electrode-arc-molten pool' electrodynamic system at each moment of time. | O.I.Shpigunova S.

| 13 | 研制生态安全的固体火箭推进剂的可能途径显示文摘本文叙述了常规火箭推进剂燃烧时产生大量污染环境,危及人类生存的有害物质,如一氧化碳和含氯化合物等致癌物。为研制生态安全的推进剂,如果不首先考虑推进剂的能量高、化学安定性和燃烧特性俱佳的氧化剂,企图进一步解决其它问题就无意义。当然成本、工艺性和力学性能因素亦很重要。在探索研制配方时,可考虑选用硝酸铵、硝酸肼、二硝酰胺、硝仿肼等氧化剂取代NH_4C1O_4和HMX。为此,本文着重介绍了由七种对化剂组成的配方并进行了热力学计算,结果表明以NH_4N(NO_2):及N_2H_5C(NO_2)3为基的配方的能量均高,而其燃烧室和喷管温度则分别低于以NH_4C1O_4和HMX为氧化剂的推进剂燃烧产生的高温。就上述氧化剂热分解参数而言,在20℃下,热分解0.1%所需时间,以Na-C1O_4的为最长,以NH_4N(NO_2)_2的为最短。其顺序为:N_aC1o_4>NH_4N)_3>β-HMX>N_2H_5NO_3>NH_4C1O_4>N_2H_5C(NO_2):>NH_4N(NO_2)_2。文中对上述氧化剂的燃烧速率、压力指数和温度系数分别进行了实测和计算,除HMX外,所得两值均较一致;还介绍了燃烧速率与氧化剂产物分解比? | Manilis G B(Institute of Chemical Physics in Cherogolovka,Russian Academy of Sciences) | 1995 | 含能材料1995,3,2: | 1 |

| 20 | Role of Ordering Energy in Formation of Grain Structure and Special Boundaries Spectrum in Ordered Alloys with L12 Superstructure显示文摘It was revealed that an average energy of special boundaries is proportional to APB energy in the alloys with the L12 superstructure. This fact proves the appearance of the GAPBs in the planes of location of special boundaries in coincidence sites of ordered alloys. It was determined that the more energy of special boundaries in ordered alloys, the more energy of complex stacking fault. There is a correlation between the distribution of special boundaries as a function its relative energy and ordering energy: the more ordering energy, the more degree of washed away of distribution. The correlation between average relative energy of special boundaries and ordering energy was detected: the more ordering energy, the more average energy of special boundaries. The reverse dependence between ordering energy and average number of special boundaries in grains limited by boundaries of general type was discovered. | O.B.Perevalova (Institute of Strength Physics and Material Science, Russian Academy of Sciences, Siberian Branch pr.
