重力固体潮的计算无论是在流动重力观测的校正还是在固定台站重力观测值的校正上都是必不可少的,并且很大程度上决定了最终结果的准确性.固体潮的计算程序比较成熟,但是目前大多数程序所采用的公式、参数和方法比较陈旧.为了提高计算结果的时效性和准确度,经过对原公式的详细分析和计算程序的改进,本文给出一个改进的计算公式和计算方法.特别在计算儒略日和六个天文参数时采用J2000.0系统,更合时宜.另外,Matlab是非常优秀的数学计算软件,本文利用Matlab的优势,重新编写固体潮计算程序,最后利用改进的计算程序给出一个计算实例,证明了程序的可靠性和结果的精确性,得到较好的结果.因此,本文利用新参数和软件改进重力固体潮计算程序的方法是成功的,值得在相关计算领域推广. The calculation of gravity tide is essential both for the correction of gravity observations and for the correction of gravity observations at fixed stations, and to a large degree determines the accuracy of the final result. Mature, but most of the procedures used in the current formula, parameters and methods are outdated.In order to improve the timeliness and accuracy of the calculation results, after a detailed analysis of the original formula and the improvement of the calculation program, this paper gives an improved formula And calculation method.Moreover, J2000.0 system is more suitable when calculating Julian day and six astronomical parameters.Moreover, Matlab is a very good mathematical calculation software.This paper uses the advantage of Matlab to rewrite the calculation program of solid tide, At last, an improved calculation program is given to give a calculation example, which proves the reliability of the program and the accuracy of the result and gets better results.Therefore, the method of using the new parameters and software to improve the gravity tide calculation program is successful, It is worth promoting in the related calculation field.
