| 摘 要： | 测边网平差可按间接平差法进行,也可按条件平差法进行,通常多按条件平差法进行。因为后者工作量比前者要小,而条件平差工作量的大小在很大程度上又取决于条件式系数计算的简便程度。因此研究测边网条件式系数的实用简便算式,具有一定的实用意义。本文以一种新的途径研究了测边网条件平差系数的计算方法,它不同于现有的一般计算

| Abstract: | Method of calculating coefficient for the conditional equation based on the ratio of observed sides of trilateration nets is discussed in this paper.The calculating formulae are first derived from a few typical simple figures by the principle of angular closure,Then based on the rule of the derived formulae,the method of calculating coef- ficient is explained.The paper indicates that the rule of the derived formulae can be applied the same way to the case of more than two conditional equations.An example fo... |
