Claim 7:
8. The non-destructive testing method for the elastic modulus of the fine ceramic according to claim 2, further comprising:
performing testing according to the grades of the mechanical property to form a regression analysis sample, and fitting and creating a relation curve of resilience-ultrasonic for testing the elastic modulus of the fine ceramic;
using the built data model according to the obtained resilience effective value and the ultrasonic effective values to perform calculation and analysis to obtain the elastic modulus E; and
obtaining an effective numerical value of the elastic modulus E of each test sample in each group, and taking an arithmetic mean value as the elastic modulus E′ of the group of test samples.
