在单三角锁两组严密平差里,第一组条件方程式的解算是对三角形闭合差进行平均配赋,作为第一次改正数;而解算第二组条件方程的关键是计算其余各条件方程的系数和改化系数,其中计算坐标条件系数和改化系数较烦琐。按传统的计算程式难于在小容量的电子计算器(机)上进行连续的程序运算。 In the two sets of tight adjustment of the single triangle lock, the solution of the first set of conditional equations is the average assignment of the triangle closed difference, as the first correction; and the key to solving the second set of conditional equations is to calculate the remaining conditions The coefficient of the equation and the coefficient of modification, wherein the calculation of the coordinate condition coefficient and the modification coefficient are more cumbersome. According to the traditional calculation program is difficult in small-capacity electronic calculator (machine) for continuous program operation.
