| 摘 要： | 讨论了尘埃粒子解的时空结构及其性质，导出了尘埃粒子的内空间的离散结构.证明了尘埃粒子内部的物质球是一个无坐标的平直球，因而具有最小的体积和整体的关联性.导出了在尘埃粒子的内外时空中的径向测地线并说明其连续性.阐述了由这个解所揭示的物质、引力与时空之间的内在联系.

| Abstract: | The spacetime structure and properties of the solution of dust particle are discussed. We derive the discrete structure of interior space of dust particle, and prove that the matter ball in the interior of dust particle is a flat ball without coordinates and has minimal volume and unitariness. Then, we derive the radial geodesics in the interior and exterior spacetime of dust particle and prove its continuity. Finally, we expound the inherent links between matter, gravitation and spacetime which were brought to light in the solution of dust particle. |
