数种不同情况下所用的计算式,若能系统归纳成一个通用公式,则可简化计算程序。为此,笔者在学习了“在曲线桥梁中偏角乘率法的应用”一文(以下简称原文,见本刊1979年第9期)之后,归纳出一个偏角乘率c_n的通用公式: c_n=3jt_n+3kL_s±j~3/l′ (1) (前视用+,后视用-) 式中l′——观测曲(直)线段(置镜点至观测点)全长、(米); Several different situations using the formula, if the system can be summarized into a common formula, you can simplify the calculation program. Therefore, after learning the article “Application of Declination Method in Curved Bridge” (hereinafter referred to as the original text, see the article No. 9 of 1979), the author summed up a generic formula of angle-angle multiplier c_n: c_n = 3jt_n + 3kL_s ± j ~ 3 / l (1) (forward looking +, rear view using -) where l ’- the total length of the observation curve );
