-
摘要: 本文讨论了根据重复水准、重力测量资料利用虚拟质点法计算水准面随时间的变化,提出了虚拟质点位置参数的优化方法(该法克服了司托克斯方法和配置法的缺点)。模拟计算表明,水准面位移的计算精度是很高的。Abstract: In this paper the computation method of geoid variation with time by repeated level-ling and gravimetry is discussed by the authors.The optimization method of positional parameters of fictitious point masses is presented.The fictitious point mass method over-comes the disadvantage of stokes integral and collocation.Simulated computation shows that the computed geoid variation is very accurate.
