This invention belongs to the field of radiative heat transfer technology, specifically relating to a method for obtaining the radiation characteristics of divergent suppressed particles. The calculation results of the absorption factor and scattering factor obtained by this method are in good agreement with those obtained by traditional Mie scattering calculations. When the shape factor increases to the point that traditional Mie scattering calculations diverge, the proposed divergent suppressed particle radiation calculation method does not diverge, effectively solving the divergence problem that occurs in traditional Mie scattering calculations when the shape factor increases. By introducing the divergent suppressed Riccati-Bessel formula and stepwise recursive calculations, the stable calculation of the absorption factor Qa and scattering factor Qs is ensured, avoiding divergence and thus improving the reliability and accuracy of particle radiation characteristic calculations.

This invention provides a method and system for verifying the accuracy of tidal force estimation. By calculating the tidal force at a given measuring station and the force exerted by the Earth on the station, the total change in gravitational acceleration at that station is calculated and matched with data collected by a gravimeter. Positioning is then performed using a gravitational positioning method. The accuracy of the tidal force calculation is evaluated based on the positioning accuracy, thus verifying the accuracy of the tidal force estimation. Due to error propagation, even small errors in the tidal force calculation will manifest as significant positioning errors in the positioning results. This invention, by verifying the tidal force through the positioning results, can greatly improve the verification accuracy.
