3.The Inverse Compton Contribution to Medium-Latitude Galactic Diffuse Gamma Rays
4.The gamma-ray emissivity q/4π of galactic cosmic rays interacting with inter-staller gases at medium-latitude(|b| = 10°- 20° )is determined by using recent EGRET data.
5.Using the recorded phase data of VLF wave (16 kc/s) transmitted by GBR (England) we have obtained the VLF phase drift and the electron density change in the D-region in the mid-latitude during the galactic cosmic ray storms (Forbush decrease) and the strong geomagnetic storms.
