龙超清地方主义的表现及其对井冈山斗争的影响

龙超清对江西特别是对湘赣边的工农革命，对建立井冈山革命根据地，作出了重大贡献；但是，龙超清的地方主义，对井冈山斗争产生了极为不利的影响：1．把地方主义和土客籍矛盾带到党的工作中来，使党的组织严重不纯；2．把地方主义和土客籍矛盾带到打土豪分田地斗争中来，造成宁冈三次分田都未分好；3．把地方主义和土客籍矛盾带到干部工作中去，造成一些重要干部被错杀。     

井冈山革命根据地军事体育研究

基于对影响井冈山根据地军事斗争的因素如作战地理环境、武器装备条件、战术需要、后勤保障等的分析,井冈山根据地领导人从军事体能、军事技能、战术训练、军事体育表演、实战演习等方面对广大指战员进行了有效的训练,大大增强了部队的战斗力。井冈山革命根据地军事体育在后来的革命中得到很好的延续发展,影响深远。     

井冈山时期毛泽东的党建思想及其现实启示

井冈山根据地是中国共产党建立的第一块农村革命根据地,从这里中国共产党开始了独立领导中国革命的历程。井冈山时期是中国共产党的初创时期,毛泽东为领导的中国共产党人对党的思想、组织和作风等各方面建设进行了可贵的探索。在农村根据地艰苦的条件下形成了丰富的党建思想,在艰难的革命环境中开辟了一条中国特色的民主革命道路。毛泽东关于党的建设思想不仅为井冈山时期革命根据地党的建设起到了重要的作用,保证中国革命走上正确道路,最终赢得革命胜利,同时也为今天中国共产党的建设提供了宝贵的借鉴。     

Improving the accuracy of GRACE Earth’s gravitational field using the combination of different inclinations

In this paper, the GRACE Earth＇s gravitational field complete up to degree and order 120 is recovered based on the combination of different inclinations using the energy conservation principle. The results show that because different inclinations of satellite are sensitive to the geopotential coefficients with different degrees l and orders m, the design of GRACE exploiting 89° inclination can effectively improve the accuracy of geopotential zonal harmonic coefficients. However, it is less sensitive to the geopotential tesseral harmonic coef- ficients. Accordingly, the second group of GRACE exploiting lower inclination is required to determine high-accurately the geopotential tesseral harmonic coefficients and cover the shortage of the single group of GRACE exploiting 89° inclination. Two groups of GRACE individually exploiting 89° ＋ （82°-84°） inclinations are the optimal combination of the Earth＇s gravitational field recovery complete up to degree and order 120. In the degree 120, the joint accuracy of cumulative geoid height based on two groups of GRACE individually exoloiting 89° and 83° inclinations is averagely two times higher than the accuracy of a group of GRACE exploiting 89~ inclination.     

动车组运营下轨道参数对小半径曲线钢轨侧磨影响研究

为减缓动车组运营下小半径曲线外股钢轨侧磨,延长钢轨使用寿命,利用SIMPACK软件建立了小半径曲线轮轨磨耗仿真模型。仿真分析了超高、轨距、钢轨表面摩擦系数及轨底坡对动车组通过时小半径曲线外轨所受横向力、导向轮冲角及轮轨磨耗指数的影响规律。研究结果表明:钢轨表面摩擦系数及轨底坡对小半径曲线外轨侧磨影响较大,适当降低钢轨表面摩擦系数可以较大程度上降低曲线外轨所受横向力及磨耗指数;调整外轨轨底坡至1∶20,内轨轨底坡至0,对曲线外轨所受横向力及导向轮冲角影响较小;但对轮轨磨耗指数影响较大,有利于减小曲线外轨侧磨。根据研究结果,针对某动车所小半径曲线制定了减磨方法;并对改造后曲线进行了轮轨力测试和钢轨廓形测试。测试结果表明,减磨方法效果明显,可延长曲线外轨服役寿命3倍以上。     

Origin of the Moon's orbital inclination from resonant disk interactions

The Moon is generally believed to have formed from the debris disk created by a large body colliding with the early Earth. Recent models of this process predict that the orbit of the newly formed Moon should be in, or very near, the Earth's equatorial plane. This prediction, however, is at odds with the known history of the lunar orbit: the orbit is currently expanding, but can be traced back in time to reveal that, when the Moon formed, its orbital inclination relative to the Earth's equator was I approximately = 10 degrees. The cause of this initial inclination has been a mystery for over 30 years, as most dynamical processes (such as those that act to flatten Saturn's rings) will tend to decrease orbital inclinations. Here we show that the Moon's substantial orbital inclination is probably a natural result of its formation from an impact-generated disk. The mechanism involves a gravitational resonance between the Moon and accretion-disk material, which can increase orbital inclinations up to approximately 15 degrees.     

关于高师生物学实验如何与基础生物学实验接轨探讨

生物学作为一门应用性、实践性和实验性极强的学科 ,在基础教育阶段 ,人们对实验教学的重视程度越来越高。新的教学大纲以及新的教材体系也充分显示了对实验的重视。包括一些新的学习方法的提出 ,象探究性学习、研究性学习、创新性学习等等在教学中的运用 ,使得人们重新审视实验在生物学中的地位。由此也对于从事基础生物学教学的老师提出了新的更高的要求 ,老师必须具备极高的从事实验操作和实验教学以及科学研究能力 ,才可能胜任当前的基础教育改革形势 ,这无疑也对高师人才的培养体系和培养方式提出了新要求。分析形势我们会发现高师有很多地方与基础生物学不适应 ,需要高师加大实验改革力度以与基础生物学接轨。     

湍流场中涡线单元的结构分析

与描述湍流速度场的流线管单元[Wang L. On properties of fluid turbulence along streamlines. J Fluid Mech,2010, 648:183–203]的思想类似,为了描述湍流涡矢量场的结构,我们提出了一种新的结构分析方法,即涡线单元,可以用单元尺度和极值点涡量差值来表征.涡线单元与常用的涡管结构的不同可以概括为:涡线单元结构可以定量描述,并且是全空间填充的.在理论上这两个条件是保证我们可以将涡线单元的结构分析与全流场统计规律联系起来的必要前提,帮助理解和重构湍流涡量场.根据直接数值模拟数据,我们研究了涡线单元的统计与结构特性,包括尺度与手性等.根据涡线单元结构可以定量表征精细的条件统计,例如发现涡相关的动力学参数(例如拟涡能耗散率和涡拉伸率)强烈依赖于基于涡线单元结构的条件统计.这样一种结构分析方法为深入研究湍流场提供了新的手段.

Origin and evolution of new genes

Organisms have variable gcnome sizes and contain different numbers of genes. This difference demonstrates that new gene origination is a fundamental process in evolutionary biology. Though the study of the origination of new genes dated back more than half a century ago, it is not until the 1990s when the first young genejingwei was found that empirical investigation of the molecular mechanisms of origination of new genes became possible. In the recent years, several young genes were identified and the studies on these genes have greatly enriched the knowledge of this field. Yet more details in a general picture of new genes origination are to be clarified. We have developed a systematic approach to searching for young genes at the genomic level, in the hope to summarize a general pattern of the origination and evolution of new genes, such as the rate of new gene appearance, impact of new genes on their host genomes, etc.     

Chaos-assisted capture of irregular moons

It has been thought that the capture of irregular moons--with non-circular orbits--by giant planets occurs by a process in which they are first temporarily trapped by gravity inside the planet's Hill sphere (the region where planetary gravity dominates over solar tides). The capture of the moons is then made permanent by dissipative energy loss (for example, gas drag) or planetary growth. But the observed distributions of orbital inclinations, which now include numerous newly discovered moons, cannot be explained using current models. Here we show that irregular satellites are captured in a thin spatial region where orbits are chaotic, and that the resulting orbit is either prograde or retrograde depending on the initial energy. Dissipation then switches these long-lived chaotic orbits into nearby regular (non-chaotic) zones from which escape is impossible. The chaotic layer therefore dictates the final inclinations of the captured moons. We confirm this with three-dimensional Monte Carlo simulations that include nebular drag, and find good agreement with the observed inclination distributions of irregular moons at Jupiter and Saturn. In particular, Saturn has more prograde irregular moons than Jupiter, which we can explain as a result of the chaotic prograde progenitors being more efficiently swept away from Jupiter by its galilean moons.     

Origin of the orbital architecture of the giant planets of the Solar System

Planetary formation theories suggest that the giant planets formed on circular and coplanar orbits. The eccentricities of Jupiter, Saturn and Uranus, however, reach values of 6 per cent, 9 per cent and 8 per cent, respectively. In addition, the inclinations of the orbital planes of Saturn, Uranus and Neptune take maximum values of approximately 2 degrees with respect to the mean orbital plane of Jupiter. Existing models for the excitation of the eccentricity of extrasolar giant planets have not been successfully applied to the Solar System. Here we show that a planetary system with initial quasi-circular, coplanar orbits would have evolved to the current orbital configuration, provided that Jupiter and Saturn crossed their 1:2 orbital resonance. We show that this resonance crossing could have occurred as the giant planets migrated owing to their interaction with a disk of planetesimals. Our model reproduces all the important characteristics of the giant planets' orbits, namely their final semimajor axes, eccentricities and mutual inclinations.
