| description | The invention relates to a comet quasi bound state dust dynamics modeling method considering ice content. According to the method, a comet dust dynamic model is established according to comet nucleus gravitation, solar gravitation, sunlight pressure, gas acting force and sublimation recoil force, a dust surface ice coverage rate coefficient is introduced, and the analysis of the content of the dust surface ice can be realized, specifically, the method comprises the following steps: step 1, establishing a dust surface temperature model; 2, establishing a comet orbital coordinate system; and 3, establishing a quasi bound state dust kinetic equation. According to the method, on the basis of the escape-state dust kinetic model, the gas acting force and the sublimation recoil force are additionally considered, the quasi-bound-state dust kinetic model is established, and the movement of the quasi-bound-state dust can be solved through the model. And meanwhile, the dust surface ice coverage rate determines the subli |
