摘要：
A resonance-ultrasound microscopy has been developed to measure material's local Young's modulus. It detects the effective Young modulus through a resonance frequency of a langasite (La3Ga5SiO14) oscillator touching the specimen. The vibration of the oscillator is excited and detected with a surrounding solenoid coil in a noncontacting way and it can be affected only by the contact with the specimen, achieving an absolute quantitative measurement.
