摘要
在测量平差概述的教学过程中,通过对必要量、观测量、必要观测量、多余观测量、必要起算数据、多余起算数据等几个概念之间关系的分析,有助于学生理解与掌握平差数学模型的建立,教学效果较好。
In the teaching process of surveying adjustment, analysis is made on the relations among several concepts,such as necessary elements,observation elements, necessary observation elements, redundant observation, necessary initial data and unnecessary initial data. It will be helpful for students to understand mathematic model of surveying adjustments which has been proved by the teaching practice.
