摘要：
A new class of solutions of Einstein field equations has been investigated for inhomogeneous cylindrically symmetric space-time with string source. To get the deterministic solution, it has been assumed that the expansion (theta) in the model is proportional to the eigen value sigma(1)(1) of the shear tensor sigma(i)(j) . Certain physical and geometric properties of the models are also discussed.
