摘　　要：边角网采用条件平差时,多余观测数较多,条件方程的列立需考虑边角两类观测量形成的各种条件,可列立的条件方程数量和类型都比较多。本文结合笔者多年教学经验,对边角网可列立的各类条件进行综合分析对比,提出条件选择时可行的方法和建议。Features and Picking of Various Type Conditions in the Condition Adjustment of the Triangulateration Network and the Earth Quadrilateral—Conditional adjustment method was used by the triangulateration network,the number of redundant observations was more. Establishment of the condition equations need to be considered a variety of conditions formed by the two type observables of the corners,the number and the types of the establishment of the condition equations were more. In the paper,based on the years of teaching experience,the conditions established the corners were compared and analyzed comprehensively,and methods and suggestions were provided in selecting the conditions.
