英文摘要	We construct charged black hole solutions with hyperscaling violation in the infrared (IR) region in Einstein-Maxwell-Dilaton-Axion theory and investigate the temperature behavior of the ratio of holographic shear viscosity to the entropy density. When translational symmetry breaking is relevant in the IR, the power law of the ratio is verified numerically at low temperature T, namely, eta/s similar to T-kappa, where the values of exponent kappa coincide with the analytical results. We also find that the exponent kappa is not affected by irrelevant current, but is reduced by the relevant current.
