三角測量中的現測工作,不僅本身繁雜瑣碎,还随時随地受着大气及地理环境的影响,因之造成观測过程中不少臨時的困难,所以提高观測質量,就需要我們經常的付出很大的技术力量。今年有机会实际参加一等三角观测,少有体驗,茲將目前質量中所存在的一些問題,提出共同研究,并借以發表个人的意見。 (一)消滅断光是提高观測質量的首要条件一般說在观測中的断光有两种:一是長时间的断光;一是短時间隙的断光。前者会造成某少數單角或某少數方向在同一折光条件下短時完成全部观測,旁
The current work of triangulation is not only complicated and trivial in itself, but also affected by the atmospheric and geographical environment anytime, anywhere. As a result, many temporary difficulties in the observation process are caused. Therefore, to improve the quality of observation, we often need to pay Great technical force. This year, we have the opportunity to actually participate in the observation of the first-class triangles and have few experiences. We hereby propose to jointly study some problems that exist in the present quality and make our personal opinions public. (A) eliminate the broken light is to improve the quality of the primary conditions for the observation Generally speaking, there are two kinds of broken light in the observation: one is a long time off light; one short-time gap of the light. The former will result in a small number of single corners or a few directions in the same refractive conditions to complete all observations in a short time, next to
