在闵可夫斯基四维时空中利用二维坐标图解析了双生子效应.特别对飞船转向所引起的同时线跃变而导致的地球人年龄的跃变作出了定量解析,得出了孪生子重逢时经历过加速运动的飞船人比可以看作为惯性系的地球人更年轻的绝对性结论.然后通过对解析结果的讨论并辅之以数值计算,给出了飞船往返飞行的两个不同阶段及全程在两个不同参考系的具体的观测结果. 相似文献

Inertial mass in relativity theory is discussed from a conceptual view. It is shown that though relativistic dynamics implies a particular dependence of the momentum of a free particle on its velocityin special relativity, which diverges as v approaches c, the inertial mass itself of a moving body remains constant, from any frame of observation. However, extension to general relativity does conceptually introduce variability of the inertial mass of a body, through a necessarily generally covariant field theory of inertia, when the Mach principle is incorporated into the theory of general relativity, as a theory of matter. 相似文献

A magnetized cylindrically symmetric universe with two degrees of freedom in which the free gravitational field is Petrov
type I degenerate, is obtained. The magnetic field is due to an electric current produced along the x-axis. The distribution
consists of an electrically neutral perfect fluid with an infinite electrical conductivity. The behaviour of the model when
magnetic field tends to zero and other physical aspects of the model are also discussed. 相似文献

The characteristics of the memory of accelerated motion in Minkowski spacetime are discussed within the framework of the nonlocal theory of accelerated observers. Two types of memory are distinguished: kinetic and dynamic. We show that only kinetic memory is acceptable, since dynamic memory leads to divergences for nonuniform accelerated motion. 相似文献

In this paper, we have investigated Bianchi type I inflationary universe in the presence of massless scalar field with a flat
potential. To get an inflationary solution, we have considered a flat region in which potential V is constant. The inflationary scenario of the model is discussed in detail. 相似文献
