Suggestions on Verifying Methods for Horizontal Deviation of Collimating Line in Level Verification Devices

根据水准仪检定装置的工作原理，建立了水准仪检定装置水平准线偏差检定方法的数学模型，并以三点互调式水准仪检定装置为研究对象进行了不同检定方法的比对实验，发现了不同检定方法的检定结果存在较大差异。通过分析检定方法的数学模型，提出了引起水平准线偏差测量结果不确定度的因素，指出检定结果差异的原因，证明了水平准线标准装置检定法是检定水准仪检定装置水平准线偏差的最佳方案。

Some mathematic model of verifying methods for horizontal deviation of collimating line are described , according to the operation principle of level verification device. As the experiment is performed with the three-point mode level verification device, the obvious difference from the experimental results achieved by vary verifying method is founded. The cause of the obvious difference of the experimental results is inferred from the uncertainty contributors of the horizontal deviation of collimating line which is analyzed and every mathematic model of verifying method for horizontal deviation of collimating line is described, so that an optimum scheme for horizontal deviation of collimating line in level verification devices is proved.
