Abstract:
     The invention relates to a method for measuring the sound speed inside the bone in the field of measuring technology. It comprises the following steps: arranging four sending-receiving units which can send and receive the hypersonic on the outer surface of a period of bone with the order: A1, A2, B1, and B2 in side a probe casing, arranging L as the distance between A1 and A2, B1 and B2 so as to send and receive the hypersonic between A1 and A2, B1 and B2 with the time parameter: T1、T2、T3 and T1’,T2’,T3’. When T1=T2’, the spreading speed of the hypersonic is V＝L/delta T inside the bone.
