摘要
针对普通测树角规在森林调查中存在的弊端 ,研究发明了一种能自动改正坡度的新型角规 ,详细介绍了其原理、结构设计及使用方法。经实地测试 ,精度达 97 3%。
Focusing on overcome the shortcomings of routine angle gauge using in forest measuration, a new-type angle gauge with the function of correct slope automatically was developed. The principles, design of structure and using method of this new-type angle gauge were described in detail. The results of site measuring showed that the precision attained 97.3 %.
