n: Efflux velocity decreases continuously due to diffusional effect and resistance of submerged fluid. Decreasing coefficient of jet velocity is the ratio of the circulation velocity at any point of center line of jet and circulation velocity at outflow poin

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 computer processing system of drill information produced by Martin Decker corporation .By using this kind of technology,after the digger choose the preprocessing information, the system can change the information into digital form in order to a
