森林调查所以能迅速而经济地完成,是由于瑞典林学院同Micronie公司协作研制出一种新的技术装置,该项产品已命名为SMR数据轮尺。它由一个数据终端和一个机械电子轮尺组成。这两个部件由导线连接(图1)。
The forest survey was completed quickly and cost-effectively as a result of the Swedish Institute of Forestry collaborating with Micronie to develop a new technical device that has been named SMR Data Calipers. It consists of a data terminal and a mechanical electronic caliper. These two parts are connected by wires (Figure 1).
