In terms of Dirac matrices the self dual and anti self dual decomposition of a conformal supergravity is given and a self dual conformal supergravity theory is developed as a connection dynamic theory in which the basic dynamic variables include the self dual spin connection i.
利用狄拉克矩阵对共形超引力进行自对偶—反自对偶分解得出了自对偶的共形超引力理论 。
) are triggered by tide-generating force resonance at collinearity of three stars when the internal conditions are satisfied.
运用中华传统文化的整体思维和现代统计学、气象学、地震学原理 ,发现特大暴雨、台风突变和大地震临震、火山爆发等突发性特大自然灾害 (均为当前公认的世界性科学难点 ) ,都是在内部条件基本具备情况下 ,由月亮为主的“三星一线”时的引潮力共振异常叠加而触发。
In this paper,the author proposed an approach to analysis facility service areas,named gravity polygon,which is based Reilly s model and Huff s model,constructed by geography spatial interaction theory.
文章以地理学区位分析理论中的空间相互作用模型为基础,提出了基于引力模型的设施服务域分析———引力多边形方法;并在GIS分析环境,建立了以Huff模型为例的引力多边形服务域算法。
For low-moon(or low-Mars) orbit satellites,the eccentricity is mainly caused by odd zonal coefficients in non-spherical gravitation of a central body.
对于地球低轨卫星,主要受大气耗散作用的影响,而对环月(或环火星)低轨卫星,主要受非球形引力位中奇次带谐项的影响,会出现变幅较大的长周期变化,从而导致近星点高度h_p在一段时间内有明显的下降趋势。
Moreover, the quasiconformal Schwarz lemma is improved by these new properties.
同时，运用这些性质，改进了拟共形Schwarz引理。
