Isotope, английский
- An isotope represents atoms of the same element that have the same number of protons but a different number of neutrons . they therefore have different atomic masses but the same chemical properties. a radio-isotope is an isotope which is radioactive .
- A form of a chemical element which has the same chemical properties as other forms but a different atomic mass
Isotope (rt), английский
One of several nuclides having the same number of protons in their nuclei, and hence belonging to the same element, but differing in the number of neutrons, and therefore in mass number. small quantitative differences in chemical properties exist between elements and isotopes. isotopes may or may not be unstable. unstable isotopes undergo transitions to other isotopes or elements with a loss of energy. such energy is usually given off in the form of electromagnetic or particle radiation. isotopes are used as source of radiation for radiography.
Isotope cask, английский
Isotope container; isotope can; isotope flask, английский
Isotope-powered thermoelectric generator, английский
Радиоизотопная термоэлектрическая батарея
Isotopes, английский
Изотопы. нуклиды, имеющие один и тот же атомный номер, но различное массовое число (мос, 5). (атомный номер равен числу протонов, массовое число.— это число нуклонов, т. е. число протонов и нейтронов). все изотопы данного элемента имеют идентичные химические свойства, но различную атомную массу; одни могут быть радиоактивными, другие — нет. 6—1113 jet, overfire — верховая струя. струя воздуха или пара, подаваемая для усиления турбулентности над топливным слоем в печи и тем самым для снижения образования дыма. к
Parent, английский
- A biological or adoptive mother or father verb to carry out the role of a parent ‘…in most paediatric wards today open visiting is the norm, with parent care much in evidence. parents who are resident in the hospital also need time spent with them’ [nursing times]
- Same as birth mother, birth parent
- Порождающая м-последова- тельность м-последова- тельность, используемая для формирования других последовательностей, напр., последовательность йетса-хоулгейта см.также yates-holgate sequences, single correlation sy s tem
- A device, bus, function, or process at one level of a hierarchy. the parent controls the behavior of components below it in the hierarchy.
- In a tree structure, an element that contains subordinate elements called child elements.
- The controlling side of a hierarchical relationship. in a hierarchical structure, a parent has one or more child nodes directly beneath it in the hierarchy.
Parent account, английский
An account that is above other accounts in the hierarchy to which any action taken on the main account entity can propagate to.
Parent activity, английский

Parent business unit, английский

Parent cache server, английский
In a multi-tiered cache hierarchy, a disk-based cache proxy/server that sits between the edge cache node and the origin server.
Parent category, английский
An entity used in catalogs to group a set of products in a hierarchy. for example music is a parent category and rock jazz and classical are child categories.

Mass spectrometer, английский
- A device used to identify the kinds of molecules present in a given substance: the molecules are ionized and passed through an electromagnetic field. the way in which they are deflected is indicative of their mass and identity.
- Analytical technique that detects the identity and amount of elements and molecules present in a sample by first ionizing, separating the ions through electromagnetic forces, and then measuring their mass-to-charge ratio. data is presented as a mass spectrum of ion signal as a function of the mass-to-charge ratio. in leak testing, use of a mass spectrometer leak detector specially tuned for helium detection is common. compare spectrometer.
