摘要
本文讨论了测距仪的加常数a、乘常数b和距离改正数ΔS(=a+bS)的显著性检验问题。讨论的结果表明,加常数和乘常数的显著性并不能决定距离改正数的显著性。所以,我们应当对距离改正数进行显著性检验,以决定是否用它来对观测边长进行改正。本文还从公式论证和模拟试验两个方面讨论了距离改正数的检定精度及其可靠性问题。
In this paper,the significant test problems of additive constant a,multiplication constant b and distance correction △S (= a+bS) are discussed. The result make it clear,that the significance of △S is not decided by significance of a and b. Therfore,we should test the significance of △S to decide,if the measured distance need to be corrected. The problems of test accuracy and reliability of distance correction are also discussed theoretically and analogically.
