| 摘 要： | 利用误差传播律和点在任意方向的位差理论，提出并论证了交通线路上任一点对应中桩的横向位差为零，纵向位差等于该点的点位误差。对中桩的误差曲线和误差椭圆的分析认为，误差椭圆无实际意义，误差曲线实用而有效。

| Abstract: | On the basis of the error spread law and the theory of position error in arbitrary direction of point,it is put forward and demonstrated that transverse position error equals to zero and longitudinal position error equals to the error of point position.Besides,error curve and error ellipse are analyzed.So,it is shown that error ellipse is inutility,and error curve is useful and effective. |
