| According to the specification and technical requirement of the national skills competition
in higher vocational colleges occupation group " Surveying and mapping ", where it gave a connector
layout, especially the calculation about traverse coordinate calculate and coordinate inverse calculation in
competition. This paper made a systematic review, combined with an engineering calculation, reveals the
scores accounted for 70% of the traverse calculation content, especially the inner peace (Σ βi) difference,
two coordinate increment (Σ xi,j、Σ yi,j), adjustment calculation and relative error (K) was the calculation
process. At last, combined with the experience of participating in the competition, the experience and
training suggestions were given |
平差、两个坐标增量
、
平差计算及导线相对误差K值的计算过程。最后结合参赛经验总结给出了心得体会及训练建议。
