atmospheric inversion
A temperature inversion in the atmosphere in which the temperature, instead of falling, increases with height above the ground. With the colder and heavier air below, there is no tendency to form upward currents and turbulence is suppressed. Inversions are often formed in the late afternoon when the radiation emitted from the ground exceeds that received from the sinking sun. Inversions are also caused by katabatic winds, that is cold winds flowing down the hillside into a valley, and by anticyclones. In inversion layers, both vertical and horizontal diffusion is inhibited and pollutants become trapped, sometimes for long periods. Low-level discharges of pollutants are more readily trapped by inversions than high level dischargers, hence the case for high stacks. Furthermore, high level discharges into an inversion tend to remain at a high level because of the absence of vertical mixing. (Source: GILP96)

Earth-Sun relationship
The Earth depends on the sun for its existence as a planet hospitable to life, and solar energy is the major factor determining the climate. Hence, conditions on the sun and conditions on Earth are inextricably linked. Although the sun's rays may appear unchanging, its radiation does vary. Many scientists suspect that sunspot activity has a greater influence on climatic change than variations attributed to the greenhouse effect. (Source: WRIGHT)

persistence of pesticides
The ability of a chemical to retain its molecular integrity and hence its physical, chemical, and functional characteristics in the environment through which such a chemical may be transported and distributed for a considerable period of time. (Source: GILP96)

taxation policy
The use of government tax and spending policies to achieve desired macroeconomic goals. Accordingly, they involve discretionary efforts to adjust governmental tax and spending to induce changes in economic incentives and, hence, to stabilize fluctuations in aggregate demand. (Source: INDEDU)

5 система физических величин

система физических величин
система величин
Совокупность физических величин, образованная в соответствии с принятыми принципами, когда одни величины принимают за независимые, а другие определяют как функции независимых величин.
Примечание. В названии системы величин применяют символы величин, принятых за основные. Так система величин механики, в которой в качестве основных приняты длина L, масса М и время Т, должна называться системой LMT. Система основных величин, соответствующая Международной системе единиц (СИ), должна обозначаться символами LMTIQNJ, обозначающими соответственно символы основных величин - длины L, массы М, времени Т, силы электрического тока I, температуры Q, количества вещества N и силы света J.

system of quantities
set of quantities together with a set of non-contradictory equations relating those quantities
NOTE – Ordinal quantities, such as Rockwell C hardness, are usually not considered to be part of a system of quantities because they are related to other quantities through empirical relations only. Nominal properties, such as colour of light, are not quantities and hence are not part of a system of quantities.

système de grandeurs, m
ensemble de grandeurs associé à un ensemble de relations non contradictoires entre ces grandeurs
NOTE – Les grandeurs ordinales, telles que la dureté C de Rockwell, ne sont généralement pas considérées comme faisant partie d'un système de grandeurs, parce qu'elles ne sont reliées à d'autres grandeurs que par des relations empiriques. Les propriétés qualitatives, telles que la couleur d’une lumière, ne sont pas des grandeurs et ne font donc pas partie d’un système de grandeurs.

caesium
A soft silvery-white and highly reactive metal belonging to the alkali group of metals. It is a radiation hazard, because it can occur in two radioactive forms. Caesium-134 is produced in nuclear reactors, not directly by fission, but by the reaction. It emits beta- and gamma-radiation and has a half-life of 2.06 years. Caesium-137 is a fission product of uranium and occurs in the fallout from nuclear weapons. It emits beta- and gamma-rays and has a half-life of 30 years. Caesium-137 was the principal product released into the atmosphere, and hence the food chain, from atmospheric testing of nuclear weapons and from the Windscale fire and Chernobyl nuclear accidents. After the Chernobyl accident, which spread a radiation cloud across Europe, the European Commission proposed new and more restrictive limits on levels of caesium in food and drinking water.
