摘　　要：目前大多数的教材对附有限制条件的条件平差有现成的公式,但总体来说计算比较复杂。文章提出了一种新的方法,从消除限制条件出发,把非独立参数表达成独立参数的函数,从而把附有限制条件的条件平差转化为附有参数的条件平差,达到求解简单的目的。文章的研究也证明了目前有的教材删除附有限制条件平差的正确性。At present, many courses have existed formulas about condition adjustment with constraints, but it is difficult to do the computation for these formulas on the whole. The paper provided a method that eliminates constraint conditions and translates the dependent parameters into the function of independent parameters, by which the condition adjustment with constraints is converted into that with added parameters by simple computation. Moreover, the result proved the correctness to eliminate the part of condition adjustment with constraints in some courses.
