摘要
1、本文根据误差传播理论,推导出导线网点权数的计算公式;角度和距离测量的必要精度的计算公式.2、实例说明在作方案设计时,初步估算导线网点必要精度的计算方法和步骤.据此,选择适当的测角和量距仪器,拟定施测纲要,以期使导线网最后平差成果达到预定的精度要求.
1. In the paper,bassd on the law of propagation of errors,the-author- presents the formula for the calculation of the weight of- the points of traverse net; and the formula for the calculation of angles as well as the distance measurement.
2.The author explains,illustrated by the examples,the method and steps in the evaluation of the required, accuracy of the spoints of traverse net.with the proper, angular measurement and distance measurement instrument,you can
draw up an outline of 'surveying,so as to instate the result of the final adjustments of traverse net to meet the requirement of accuracy.
