本文提出了一种系统地计算开放宇宙中宇宙微波背景辐射各向异性的多重矩的方法。该公式是非常普遍的意义上说，它需要照顾的所有条款，有助于各向异性完全和严格。利用该方法，我们计算了三种典型的宇宙学模型（纯重子模型、冷暗物质模型和热暗物质模型）中负曲率对绝热和等曲率初始密度涨落的影响
We formulate a method to calculate systematically any multiple moment of the cosmic microwave background (CMB) anisotropy in an open universe. The formulation is very general in the sense that it takes care of all the terms which contribute to the anisotropy completely and rigorously. Using the method, we evaluate the effect of negative curvature to the quadrupole moment in the three representative cosmological models (pure baryonic, cold dark matter and hot dark matter models) for adiabatic and isocurvature initial density fluctuations with power-law spectra
