最近，广西林业科学研究院苏滴荒同志研制的测距尺，已获得国家专利。该测距尺构造简单，便于操作、精确度高、实用性强，它能测量距离，测量间隔（高度、宽度），测量角度（密位），测量森林蓄积量，测量坡度和坡长等。小工具，大用途，很值得推广应用。　　测距尺用途广泛， Recently, the distance measuring ruler developed by Comrade Su Shuhuang of Guangxi Academy of Forestry has won the national patent. It has simple structure, easy operation, high accuracy and practicality. It can measure distance, measurement interval (height and width), measurement angle (density), measure forest volume, measure slope and slope length. Gadgets, great use, it is worth promoting application. Measuring range uses a wide range,
