This paper analyzes the principle, error sources and precision of triangulated height surveying, points out the key problems about first order leveling replaced by triangulated height surveying ; and for the first time puts forward that in some given conditions, it is not only feasible but also valuable to replace first order leveling by precise triangulated height surveying, and proves it by experimentation as well
摘要通過對三角高程測量的原理、誤差來源及精度分析,指出了用三角高程測量代替一等水準的關鍵問題,第一次提出了在特定條件下用三角高程測量代替一等水準是完全可行的,並在生產實踐中得到了驗證。
