The parameter of model are confined by the observational data of the Galactichalo stars.
利用已有的晕星的观测资料限定模型的参数。

These speedy electrons interact with photons in the galactichalo, boosting some of them up to the gamma-ray energies observed in the bubbles.
这些高速电子与银河晕的光子相互作用，将它们中的一些激发，使之成为泡泡中观测到的伽马射线。

We also describe the basic principle of White Dwarf cosmochronology and its application in defining the age of the Galactic disk, globular clusters, open clusters and Galactichalo.
