Claim 3:
4. The non-destructive testing method for the flexural strength of the fine ceramic according to claim 3, wherein the step of adjusting the ultrasonic testing instrument, controlling and adjusting the positions of the ultrasonic testing probes of the ultrasonic testing instrument until the ultrasonic testing probes, the uncut intact fine ceramic test sample are located on the same plane, performing ultrasonic testing on the uncut intact fine ceramic test sample, and collecting ultrasonic testing data of the uncut intact fine ceramic test sample further comprise:
connecting an ultrasonic transmitter and an ultrasonic receiver to the ultrasonic testing instrument;
controlling the ultrasonic testing instrument to be in communication connection to the data collection mechanism;
uniformly selecting, in advance, at least eight testing points that are distributed at an equal interval at the center of each side surface of the uncut intact fine ceramic test sample in a thickness direction;
adjusting the ultrasonic transmitter and the ultrasonic receiver to the at least eight testing points on two opposite side surfaces of the uncut intact fine ceramic test sample and to be on the same plane as the two opposite side surfaces; and
performing ultrasonic testing once on each testing point, and testing data, such as a time difference, a wave velocity and an amplitude at the signal receiving moments of the two ultrasonic testing probes, to obtain an ultrasonic velocity V of each testing point.
