| 摘 要： | Measurements by using the ultrasonic technique together for electric resistance verified thatthe first sound velocity valley on cooling is mainly due to the soft-mode of driving the com-mensurate phase transition,and the second one due to the soft-mode of driving the martensitictransformation.The starting point,R_s,and finishing point,R_f,of the commensurate phasetransition of the alloy have been determined.
