| math. | analysis of dispersion | spredninganalyse |
| math. | Ansari-Bradley dispersion test | Ansari-Bradley spredning test |
| math. | binomial index of dispersion | binomisk indeks over dispersjon |
| environ. | dispersion calculation The calculation of pollutant dispersion is based on the use of air dispersion models that mathematically simulate atmospheric conditions and behaviour. Dispersion models can provide concentration or deposition estimates and can be used to evaluate both existing and hypothetical emissions scenarios | utbredelsesberegning |
| math. | dispersion index | spredningsindeks |
| math. | dispersion matrix | kovariansmatrise |
| math. | dispersion stabilising transformation | dispersjon stabiliserende transformasjon |
| math. | dispersion stabilizing transformation | dispersjon stabiliserende transformasjon |
| math. | exponential dispersion model | eksoponensiell spredning modell |
| math. | index of dispersion | spredningsindeks |
| environ. | pollutant dispersion The spreading of pollutants from a point of release in air, soil and water. The dispersion of air pollutants is heavily influenced by how and where the pollutant is emitted, e.g., by continuous low-level versus accidental releases, multiple stacks versus a few, or the height of the stacks. The nature of the local terrain meteorology and the chemistry of the released material strongly influence the pattern of regional and, finally, global dispersion and transport | forurensningsdispersjon |
| math. | subnormal dispersion | subnormal dispersjon |
| environ. | waste gas dispersion The process of breaking up and producing a diffuse distribution of the unusable aeriform fluid or suspension of fine particles in air resulting from a manufacturing process or the burning of a substance in an enclosed area | avgasspredning |
