| 具体论述了垂准仪量值溯源与传递中存在的实际问题，包括：缺少高准确度的垂准仪校准装置、垂准仪自身的重力线传感器存在误差、激光垂准仪的准确度难以保证。详细分析了重力线与铅垂线之间的关系，解释了不同地理位置铅垂线不一样的原因。阐述了解决垂准仪量值溯源与传递问题的思路。 |
| 英文摘要: |
| The practical problems in tracing and transferring the value of the plumb alignerare discussed in detail, including the lack of high-accuracy calibration device for the plumb aligner, the error of gravity line sensor of the plumb aligner itself, and the difficulty of ensuring the accuracy of the laser plumb aligner. The relationship between the gravity line and the plumb line is analyzed in detail, and the reasons why the plumb line is different in different geographical positions are explained. The idea to solve the problem of the traceability and transmission of the value of the plumb aligner is expounded. |
