In this work we have proposed a variable relation between densities of cosmic string. Bianchi type II,VIII and IX space time is explored in the context of general relativity. The field equations are solved by assuming that the shear scalar is proportional to expansion scalar. Three different cases are investigated. It is observed that strings contribute significantly in isotropy and acceleration of the universe.

字符串密度之间的可变关系

在这项工作中，我们提出了宇宙弦密度之间的可变关系。在广义相对论的背景下探索了Bianchi II，VIII和IX型时空。通过假设剪切标量与膨胀标量成比例来求解场方程。研究了三种不同的情况。据观察，弦在宇宙的各向同性和加速中起重要作用。
