摘　　要：本文应用史赖伯法则导出了测边网设立一个尺度比未知数的平差计算和精度评定公式,给出了消去尺度比未知数的算法及设立两个尺度比禾知数的平差公式。最后结合算例对设立一个尺度比未如数与不设立尺度比未知数的两种平差方法进行精度分析,得出了有益的结论。A set of formulen for the adjustment of observation equations with scale factor as the unknown in the trilateration network, and for the accuracy evaluation, are dirived. An efficient algorithm for eliminating the scale factor unknown and for the adjustment of observation equations with two scale factor unknowns is presented. An example is givan to comparing the adjustments with one scale factor and without it. Some beneficial conclusions are obtained.
