By using single point, linear and lateral scanning, the elements composition and distribution in samples can be studied in micrometer scale.

同时利用微束扫描分析可获得样品中元素的点、线、面分布信息。

In this paper, as a unit of a linear scanning radar, an angle-measuring system made up of a microcomputer (single-board or monolithic) is discussed.

本文讨论用微处理机(单板机或单片机)实现一种线扫描雷达的测角系统。
