在水准测量中利用“差数法”来计算和检核

A Method of "Margin" Use to Calculate and Check in Leveling

主要介绍在水准测量中,用一种新的方法来计算和校核。这种方法称为"差数法",它利用常数213(313)替代尺常数4787(4687)进行计算和检核。之所以称为"差数法",是因为313=5000-4687或213=5000-4787.差数就是313(213)和尺常数4687(4787)一样,水准测量的计算和检核的方法差数313(213)一样做到。尽管在计算和检核方面它们都一样重要,有时"差数法"在快速度和准确度上更胜一筹。我们能用更少的时间完成同样的工作量。多年来的实践表明这种算法是切实可行的。

This article describes a new method that use for calculate and check of leveling.This method is called the ＂Margin＂ which uses a constant 213（313） instead of feet constant 4787（4687） to calculate and check.It is called the ＂Margin＂ because 313=5000-4687 or 213=5000-4787.The Difference constant and feet constant plays the same in leveling,sometimes the difference constant has superior speed and accuracy.Using the difference constant.we can work faster.Years of practice proves that this algorithm is feasible.
