K=±1时FRW宇宙中的线性扰动

摘要

The linear perturbation equations of mass amplitude, particleamplitude, velocity and metric of FRW universe which are completely uniform in various forms can be inferred with Einstein equation and the linear perturbation theory in the case of K=±1, suggesting that the different values of K do not affect the evolution rule of early universe.%在大尺度结构中，应用Einstein方程和线性扰动理论导出K=±1时FRW宇宙中质量密度、粒子数密度、速度和度规等物理量的线性扰动方程，得出不同形状的宇宙的以上四种线性扰动方程完全一样，K的不同取值并不影响早期宇宙的演变规律.
