| 摘 要： | 通过分析觇标及仪器对中误差对测角的影响,最终确定这种误差是主要误差.觇标对中误差与对中线量误差成正比,与所测角度的两边成反比,与角度本身的大小无关;仪器对中误差与其线量对中误差成正比,与所测角的两边长度成反比,与所测角的大小有关.针对这种误差的属性,采取有效措施,减小其对测角的影响.

| Abstract: | Through analyzing the influence of centering error of survey maker and instrument to angle measurement,finally determines this error is the main error.The centering error of survey maker is proportional with the median line quantity error,with the both sides of measured angle is in reverse proportion,has nothing to do with the size angle;The centering error of instrument is proportional with its probable error of the median line quantity,with two side lengths of measured angle is in reverse proportion,with ... |
