  1. GIS application to construction and production in mines is analyzed . Data storage structure of GIS is emphatically studied . Four-dimensional spacetime data structure is integrated with mine production .

    分析了GIS在矿山建设和生产管理中的综合应用,着重研究了GIS中的数据存贮结构,将四维时空数据结构与矿井生产相联系,并探讨了矿山GIS所包含的内容。

  2. We find that the probability for the Yang-Mills baby universe to undergo a spontaneous compactification down to a four-dimensional spacetime is greater than that to remain in the original homogeneous multidimensional state .

    我们发现仅对于Yang-Millsbaby宇宙,流形紧致到四维时空的几率才可能最大。

  3. Secondly , we investigate the energy density produced by a state vector which is the superposition of three single electron states in the Dirac field in the four-dimensional Minkowski spacetime .

    然后,研究了在四维平直时空下三个单粒子态构成的量子态的负能密度。
