| 摘 要： | 作者以Mohr圆表示了平面坐标系中点位协因数的各分量。本法不仅能给出任意方向上的自协因数,也可容易表示出两正交方向间的互协因数。Mohr圆不仅全面地反映了一点的误差状态,并可解决位移检验等实际问题。文中还指出,三维空间点坐标的协因数阵存在3个与坐标系无关的不变量。

| Abstract: | The main purpose of this paper is to combine Mohr circle with analysis of positional error. The four components of weight coefficient matrix as to a point, in any rectangular plan coordinate system, can be expressed completely by the new method. The author also expounds three invariants existing in 3-d problem. |
