机械工程 进动 Basing on this discovery,a novel double-sensor vortex precession meter (DSVPM),aimed to improve measuring accuracy,was developed. 这一研究结果,为新型差动式传感器旋涡进动流量计的研制提供了理论依据。 岁差 The subsequent chapter described the method of amendment for the algorithm on the basis of previous chapter, including the precession, nutation, atmospheric refraction, and other amendments to improve the accuracy to the level of arc seconds. 第三章阐述了在上一章的基础上对中间步骤和最终结果进行修正的计算方法,包括对岁差、章动、大气折射等的修正,从而提高计算精度到弧秒的级别。
