Старение
| Русско-латинский словарь |
- , в биологии - закономерный процесс возрастных изменений организма, снижающий его адаптационные возможности и приводящий к старости. существует большое число гипотез о причинах и механизмах старения. согласно большинству современных гипотез, в основе старения лежат изменения в генетическом аппарате организма.
- Изменение физико-механических свойств материала с течением времени.
- Возникновение в органах и системах организма возрастных изменений, ограничивающих его
- Физико-химические негативные изменения, происходящие в составе смазывающего вещества и возникающие в результате окисления и воздействия теплового и светового излучения.
- (1) результат воздействия на материалы окружающей среды в течение длительного интервала времени. (2) процесс обработки материалов при воздействии окружающей среды в течение длительного времени с целью моделирования производственного срока службы.

Senescentia [ae, f], латинский
Ageing, английский
- British variant of aging. agency 1. a relationship by which one party, usually the agent, is empowered to enter into binding transactions affecting the legal rights of another party, usually called the principal, as, for example, entering into a contract or buying or selling property in his name or on his behalf. 2. an administrative branch of government (federal, state, or local).
- The fact of growing old comment: changes take place in almost every part of the body as the person ages. bones become more brittle and skin becomes less elastic. the most important changes affect the blood vessels which are less elastic, making thrombosis more likely. this also reduces the supply of blood to the brain, which in turn reduces the mental faculties.
- 1. deterioration of textile or other materials caused by gradual oxidation during storage and/or exposure to light. 2. the oxidation stage of alkali-cellulose in the manufacture of viscose rayon from bleached wood pulp. 3. originally, a process in which printed fabric was exposed to a hot, moist atmosphere. presently, the term is applied to the treatment of printed fabric in moist steam in the absence of air. ageing is also used for the development of certain colors in dyeing, e.g., aniline black. ager: a steam chamber used for ageing printed or padded material.
Vanheneminen, финский
Aging, английский
- Spontaneous change in the physical properties of some metals, which occurs on standing, at atmospheric temperatures after final cold working or after a final heat treatment. frequently synonymous with the term " age-hardening."
- Another spelling of ageing
- The life-long process of growing older; not just a later life experience
- A metallurgical change in a metal alloy resulting in an increase in mechanical properties. this change can occur in some instances at room temperatures. more often its effects are increased by holding for specified lengths of time at elevated temperatures. also known as precipitation hardening.
- (1) the effect of long term environmental exposure on materials or components. (2) heat treatment method that alters material properties and microstructure because of the duration of time at ambient (natural aging) or elevated (artificial aging) temperature. aging is commonly applied to alloys after hot working, quenching from an elevated temperature or cold working. see also precipitation hardening.

Senescence, английский
- The ageing process
- That portion of aging that begins at older ages, after one passes the point of minimum mortality, around age 12 for humans. more specifically, senescence is not a single disease. it is characterized as a generic, increased susceptibility to various age-related chronic diseases and a reduced ability to repair the damage.
