摘　　要：根据测边交会计算公式的特点,本文详细论述了一种方便、高效、自动化程度较高的三边网坐标概算的电算算法。这种算法既不需要输入辅助计算的多余数据,也不需要逐点判断解算的坐标正确与否。在只有两个已知点的情况下,这种算法只需一次人工干预就能正确地概算出控制点坐标。在有多于两个已知点的情况下,此算法不需要任何人工干预就能正确地解算出控制点坐标。This article discusses an arithmetic which can complete the trilateration network coordinate machine - reada- ble with convenience, eiticiency and automation. The arithmetic neither needs any parameter data to support to calcu- late, nor needs gradually examine the correctness of any coordinate calculated formally. If only 2 points were known, the arithmetic just needs one artificial intervention which can calculate the coordinate of control point. On the other hand, while having more than two known points, this arithmetic can calculate control point accurately without any artifi-cial interventions.
