traditional measuring techniques difficult to construct the precise underlying topography surface. Microwave remote sensing has been demonstrated as a promising technique to retrieve the underlying..., is another powerful tool for topography mapping, but it can only measure the elevation on the forest layer surface, without the ability to detect the underlying topography. To remove forest height signals......
Surface Topography of Fine-grained ZrO2 Ceramic by Two-dimensional Ultrasonic Vibration Grinding丁爱玲School of Mechanical and Automation Engineering,North University of China摘 要:surface topography and the micro structure of the two-dimensional ultrasonic vibration grinding ceramics were especially analyzed. The experimental results indicate......
