How to understand 'climb and glide occur as a parallel which leads to the creep strain having a hyperbolic sine dependence on the applied stress'?

Dear researchers: I have difficulty in understand a technical phrase written in (Perrin and Hayhurst, 1996) Creep constitutive equations for a 0.5Cr0.5Mo0.25V ferritic steel in the temperature...
