摘　　要：给出了形式简单、规律，无需初值、迭代和过渡点的优化解法公式，适合于手工计算和计算机编程；推出了空间测边交会点位精度的通用精度估算公式，并据此找到了各精度指标与各边倾角的内在关系。对应用条件提出了具体建议。In this paper, the formulae for the optimum solution method without initial values, interation and transition points are introduced, which are simple in form, quite suitable for manual calculation and computer programming. The precision formulae of position for the intersection point are derived, according that the expressions about all precision indexes with all inclined angles of linear sides are also glven. Some suggestions for using this network are proposed.
