Results of P-wave velocity (vP) and electrical conductivity measurements on anorthosite are presented from room temperature to 880C at 1.0 GPa using ultrasonic transmission technique and impedance spectra technique respectively.
Methods:Based on the law of ultrasonic transmission,principle of ultrasonic imaging,basic structure of ultrasonic diagnostic apparatus and experimental observation,influencing factors in ultrasonic echo intensity and the transmission law of medium lamella were systematically analyzed.
The relationships between ultrasonic velocity and concentrations of glucose, fructose, sucrose, and mixed solution of glucose and sucrose were determined by experimental equipment based on ultrasonic transmission properties for liquid food quality measurement.
Effect of specimen size on velocity of ultrasonic transmission through concrete
On the boundary conditions for ultrasonic transmission by partially closed cracks
A quasi-static model for the ultrasonic transmission and reflection at imperfect interfaces is developed.
Femoral neck cortical bones were removed during surgery for cortical histomorphometric evaluation and determination of elasticity indices (C33) using ultrasonic transmission method.
Although a positive association has been reported between physical activity and bone densitometry measurements in children, no studies have reported the relationship between physical activity and ultrasonic transmission in bone in children.
