内容記述 | A crude estimate for the current degassing rate of He-4 on of 2.2 x 10 exp 5/sq cm/s is obtained by scaling from the amounts of helium and argon on earth. Nonthermal escape processes of helium on Mars are discussed and a nonthermal helium escape rate is calculated for each process. The helium mixing ratio in the lower Martian atmospheres and the intensity of its airglow at 584 A are calculated. |
