摘要
从实践出发,对标尺分划中心零点偏离测点与尺身倾斜共同引起的误差进行了研究,提出了偏斜误差数学模型,并通过实例分析了偏斜误差对水准测量的影响,提出了削弱此类误差的措施。
From the practice,this article studied the error commonly caused by the inconsistency between the partition center zero point deviation and the underside geometric center as well as the tilt of the level rod,and proposed the deflection error mathematical model.At the same time,through the example,the article analyzed the effects of the deflection error in leveling,and provided the measures which could eliminate or weaken such error.
