Global Geometry of 3-body Motions with Vanishing Angular MomentumⅠ

引用

Chinese Annals of Mathematics,Series b 2008年第1期29卷 1-54页

作者： Wu-Yi HSIANG eldar STRAUME Department of Mathematics University of California Department of Mathematical Sciences

Following Jacobi＇s geometrization of Lagrange＇s least action principle, trajectories of classical mechanics can be characterized as geodesics on the configuration space M with respect to a suitable metric which is the conformal modification of the kinematic metric by the factor （U ＋ h）, where U and h are the potential function and the total energy, respectively. In the special case of 3-body motions with zero angular momentum, the global geometry of such trajectories can be reduced to that of their moduli curves, which record the change of size and shape, in the moduli space of oriented m-triangles, whose kinematic metric is, in fact, a Riemannian cone over the shape space M^＊≌S^2 （1/2）. In this paper, it is shown that the moduli curve of such a motion is uniquely determined by its shape curve （which only records the change of shape） in the case of h≠0, while in the special case of h = 0 it is uniquely determined up to scaling. Thus, the study of the global geometry of such motions can be further reduced to that of the shape curves, which are time-parametrized curves on the 2-sphere characterized by a third order ODE. Moreover, these curves have two remarkable properties, namely the uniqueness of parametrization and the monotonieity, that constitute a solid foundation for a systematic study of their global geometry and naturally lead to the formulation of some pertinent problems.

Thermal and Magnetic Peculiarities of Metal-Containing Carbon Nano-Phase Formed in the Reaction of Fine-Dispersed Aluminium with Dichlorethane in Paraffin Medium

Electron magnetic resonance (EMR) spectroscopy, X-ray-fluorescent microscopy (XFM) and thermal analysis (TGA/DTA) are used to characterize the carbon nano-phase obtained in the reaction between fine-dispersed aluminum and dichloroethane in the liquid paraffin medium and its modified with Mn(II), Fe(III), Ni(II), Cu(II) chlorides forms were studied.. It was shown that the solid nano-structured functionalized carbon systems containing metals possess specific magnetic and thermal properties. Key parameters of the process, influencing on the size and structure of the formed carbon nano-phase were determined. Results and regularities established in this work create presumably the certain basis for optimization of physical and chemical properties of similar systems

[背景]年幼时受到低或中等剂量放射性碘131(131I)暴露导致的甲状腺功能紊乱是一个公共卫生问题。然而,鲜见有关这些常见疾病的131I相关风险的定量数据。[目的]评估甲状腺功能紊乱的发病率与童年(≤18岁)时受到来自切尔诺贝利事故放射性微尘131I暴露的关联。[方法]在一项白俄罗斯队列研究中,对甲状腺功能减退、甲状腺功能亢进、自身免疫性甲状腺炎(AIT)、血清促甲状腺激素(TSH)浓度、甲状腺过氧化物酶自身抗体(ATPO)与基于测定的131I剂量估计之间的关联进行横断面分析。这项队列研究筛查10827名参加者的各种甲状腺疾病。[结果]暴露时的平均年龄(±SD)为(8.2±5.0)岁。甲状腺131I剂量的平均(中位数)估值为0.54(0.23)Gy(范围值为0.001～26.6Gy)。131I剂量与甲状腺功能减退(主要为亚临床型及抗体阴性)和血清TSH浓度呈显著正相关。每1Gy对于甲状腺功能减退症的附加比值比为0.34(95%CI:0.15～0.62),并随着暴露和检测时的年龄、存在甲状腺肿大、居住于城市/农村而显著变化。未发现与抗体阳性甲状腺功能减退、甲状腺功能亢进、AIT或ATPO升高之间有正关联的证据。[结论]在此白俄罗斯队列中,131I剂量与甲状腺功能减退之间的关联与以前报道的一项乌克兰队列的研究结果相一致。上述研究提供了强有力的证据表明,儿童期环境131I暴露的影响结果是甲状腺功能减退,而不是其他甲状腺疾病。
