a gamma-ray reaction in which the gamma-ray, after colliding with an electron, shifts some energy to the electron. The higher the energy loss by Compton scattering in a zone, the higher the electron concentration or density. The basis for the density log.

n: 1. the spontaneous movement and scattering of particles of liquids, gases, or solids. 2. the migration of dissolved substances from an area of high concentration to an area of low concentration.

n: A process in which the molecular ,ion or material in the solvent disperse until the uniform solution forms. Namely a process in which the molecular, ion or material move from the high concentration area to the low concentration area until the whole solu

the random scattering of particles due to kinetic energy of the particles. Affected by viscosity, density and temperature.

n: a kind of tool which can make gas frame with molecular weight surround the electron beam so as to reduce the scattering of the electron beam and improve the ability of beaking rock
