<正> A group of formulae for measuring strain rate sensitivity index is established under the conditions of constant strain rate, constant velocity and constant load. And measuring methods are given corresponding to each kind of experimental curves. Furthermore the experimental results are measured and compared on Zn-wt5 % Al alloy at room temperature (18℃), which shows that this kind of alloy is structural sensitive even at room temperature.
