以宏观协同学为基础,本文建立了一套系统的从地震历史记录数据中提取概率规律的方法。在地震活动强度描述的层次上,对应用最大信息原理分析地震活动出现的静态概率分布加以了评论。同时,利用最大定标原理进一步详尽地讨论了地震活动的时间关联性及其含时概率分布。本文所提出的公式体系,可用以对地震活动的重现概率进行无偏估计。

最近,斯普灵顿(springer)公司出版的这套协同学丛书几乎全部是论述物理、化学、生物学中的自组织结构,这本韦德里希和哈格所著的专论研究了社会学中的结构(或模式)问题。初看来,这似乎是大胆阐述如何采用物理学的概念和方法研究复杂的社会现象,可实际上十几年来业已证明了各个科学领域有一大类现象可以采用统一的原理来处理。这种统一的原理尤其适合于多体系统在宏观上组成新结构的场合。确实,这就是我十多年前给协同学下的定义,这是我综述包括社会学在内的复杂系统行为的深奥类比所依据的原理(h.哈肯:《协同学导论》,本丛书第一卷)。正如我常常指出的那样,这些原理的普遍适用性并不是偶然的,也不是物理学向其它领域的进一步推广,而是有机联系的多体系统的深刻的结构性质所决定的,这些性质服从严格的数学定律。一般说来,物理学的原理和方法可以采用两种方式用于研究社会现象。其一是根据结构类比作定性论证。它出自我的著作 Erfolgsgeheimnisse der Natur;Synergetik:Die behre Vom Zusammenwirken,现已译成英文。另一方法是根据我的同事W.韦德里希

卢瑟福散射公式的一个简明推导

大学物理 1984年第9期3卷 27-28页

作者： h.haken h. C. Wolf 钱树高希良西德

在d粒子散射中，我们来确定散射角（即偏转角）θ与碰撞参数（或称瞄准距离）p之间的关系（如图一）．粒子以速度υ0来到离核还远的一点A。假如它不偏转，它将经过离核距离为P的地点。

Recently, reconsidering the Rastall idea T_(μ;νν)^(v)=α_(,μ) through relativistic thermodynamics gives a new form for the scalar field α which led us to construct modern modified theory of gravity debugged ‘non-conserved gravity theory’ Fazlollahi 2023 Euro. Phys. J. C 83 923. This theory unlike other modified theories of gravity cannot directly explain the current acceleration expansion in the absence of the cosmological constant and or existence of other forms of dark energy. hence, in this study we have reinvestigated holographic dark energy Ρ_(X)~h^(2) in the non-conserved theory of gravity. In this context, the density and pressure of dark energy depend on the non-conserved term and density of the dust matter field. As shown, due to non-conservation effects on large-scale structures, unlike the original holographic model, our model onsets an acceleration epoch for the current Universe satisfies observations. Moreover, the interaction and viscous scenarios are studied for this model.
