查询词典 longitudinal wave

Experimental results demonstrate that when the tensile speed is fast, longitudinal volume electrical resistance decreases with the increasing of the stress, before the rupture the electrical resistance decreases to the most low, the moment the sample rupture, the electrical resistance increases suddenly. when the tensile speed is slow, longitudinal volume electrical resistance decreases with the increasing of the stress during the tensile prophase, before the rupture, the big surging of the electrical resistance occurres.
