The Prediction on the Size and Location of Internal Defects of Standing Trees Using Ultrasonic Technology

Abstract:

Article Preview

A new method was proposed to determine the size and location of the internal deficiency of the standing trees using the acoustic velocity of the ultrasonic, and the method was explained in specific on the process of how to put it into practice. Through the comparison of the experiment on defective Dahurian Larch between the ultrasonography and the Resistance Drilling, the results proved that the method was available and concluded the accuracy of this method when testing deficiency. Meanwhile, the average transmission velocity of the ultrasonic in Dahurian Larch was obtained through large amount of experimental data.
