A computer - based method and computer - readable medium containing computer - executable instructions for assimilating data collected by a time domain reflectometer and displaying more than two waves representing reflections of a pulse on conductors is provided 提供了基于计算机算法及可被计算机读出的包含着计算机可执行指令的媒体，用以接收由时域反射计收集的信息，显示导体内一个脉冲反射的两个以上的波形。
Therefore , it is necessary for guaranteeing the quality of steel plate to detect and repair the roll profile timely and exactly . this paper presents the sonic circulation and multi - pulse echo principle and designs roll profile ultrasonic measurement system based on the analysis of 3d surface measurement technology and roll profile measurement methods 本文在分析了三维面型检测的发展现状及目前辊型的检测方法的基础上，提出了声循环多次脉冲反射测量原理，并以此为基础设计了上位机化的超声波辊型测量系统。
