Dispersal, английский
- Рассеяние, дисперсия; диспергирование
- The spreading of individuals away from each other, e.g., the offspring from their parents and from regions of high density to regions of low density; (analog to diffusion, as seen with the import of the potato beetle to europe). d. capacity: d. polymorphism: two or more types of dispersal structures found within a species or among the progeny of an individual. 4 4
Dispersal airfield, английский
Dispersancy, английский
Ability of an oil to disperse and suspend potential deposit-forming materials so that they can be removed from the system when the oil is drained.
Dispersant, английский
- In lubrication, a term usually used interchangeably with detergent. an additive, usually nonmetallic ("ashless"), which keeps fine particles of insoluble materials in a homogeneous solution. hence, particles are not permitted to settle out and accumulate.
- An admixture which is capable of maintaining finely ground materials in suspension; used as a slurry thinner or grinding aid.
- A dispersing agent, often of a surface active chemical, that promotes formation of a dispersion or maintains a state of dispersion by preventing settling or aggregation.
- An additive that keeps insoluble contaminants dispersed (colloidally suspended) in a lubricant, preventing the particles from settling and accumulating. dispersants help prevent the buildup of sludge, varnish and other deposits.
- A non-metallic engine oil additive that helps to prevent sludge, varnish, etc., by keeping particles suspended in a colloidal state. similar to and ordinarily used with detergents, dispersants are capable of keeping large quantities of particles in suspension, and they are ashless when burned.
Dispersant (pt), английский
A substance for promoting the formation and stabilization of dispersed particles of one substance in another.

Disperse array, английский
Разреженный массив; разреженная матрица
Disperse dyes, английский
- A class of slightly water-soluble dyes originally introduced for dyeing acetate and usually applied from fine aqueous suspensions. disperse dyes are widely used for dyeing most of the manufactured fibers. fiber-reactive dyes: a type of water-soluble anionic dye having affinity for cellulose fibers. in the presence of alkali, they react with hydroxyl groups in the cellulose and thus are liked with the fiber. fiber-reactive dyes are relatively new dyes and are used extensively on cellulosics when bright shades are desired.

Dispersion, английский
- Увеличение ширины импульса сигнала при его распространении по оптоволокну. основной фактор, ограничивающий полосу пропускания многомодового оптоволокна.
- Дисперсия.
- Эффект расширения световых импульсов во время их передачи по оптическому волокну. дисперсия пропорциональна длине кабеля (см. также хроматическая дисперсия).
- Refers to the spread of values observed for a variable. the standard deviation is a measure of dispersion, in contrast to the mean which is a measure of central tendency or location.
- The cause of bandwidth limitations in fiber. in multimode systems, modal dispersion is caused by differential optical path lengths known as differential path delay. for singlemode systems, chromatic dispersion is a combination of material dispersion (caused by the line width of the laser source) and waveguide dispersion (caused by the difference in the speed of light in the core and the cladding of the fiber). another type of dispersion is polarization mode dispersion (pmd), which is caused by random vibration, temperature variations, and bending of the fibers known as birefringence
- (1) the variation in the refractive index of a medium as a function of wavelength. (2) the property of an optical system which causes the separation of the monochromatic components of radiation.
- The dependence of the phase velocity in a medium on the optical frequency or the propagation mode
- The stretching of light pulses as they travel in an optical fiber, which increases their duration. the temporal spreading of a light signal in an optical waveguide caused by light signals traveling at different speeds through a fiber either due to modal or chromatic effects.
- This occurs when white light is split into separate wave lengths and component colors.
- Модовая дисперсия dispersion-compensating fiber волокно с компенсацией дисперсии
- Also known as "fire," dispersion refers to the separation of white light into different colors.
- Separation of white light into spectral colours, each of which vibrates at a different frequency. also called fire.
- Sometimes referred to as fire, dispersion is the break-up of white light into a spectrum of colors.
- 1. a system consisting of finely divided particles and the medium in which they are distributed. 2. separation of light into colors by diffraction or refraction. 3. a qualitative estimation of the separation and uniform distribution of fibers in the liquid during the production of a wet-formed nonwoven fabric.
- Losses`, pi потери воды при капельном орошении за счет фильтрации за пределы очага увлажнения
- The separation of light of different frequencies due to different degrees of refraction
- In acoustics, variation of wave phase with frequency.
- In acoustics, variation of wave phase with frequency.7

Steady state modal distribution, английский
Equilibrium modal distribution (emd) in multimode fiber, achieved some distance from the source, where the relative power in the modes becomes stable with increasing distance.
Profile dispersion, английский
Dispersion attributed to the variation of refractive index contrast with wavelength.
