utilisation of calorific value
Calorific value is the heat per unit mass produced by complete combustion of a given substance. Calorific values are used to express the energy values of fuels; usually these are expressed in megajoules per kilogram. They are also used to measure the energy content of foodstuffs; i.e. the energy produced when the food is oxidized in the body. The units here are kilojoules per gram. Calorific values are measured using a bomb calorimeter (apparatus consisting of a strong container in which the sample is sealed with excess oxygen and ignited electrically. The heat of combustion at constant volume can be calculated from the resulting rise in temperature). (Source: DICCHE)

coherent system of units
system of units, based on a given system of quantities, in which the unit of measurement for each derived quantity is a coherent derived unit
NOTE 1 – A system of units can be coherent only with respect to a system of quantities and the adopted base units.
NOTE 2 – For a coherent system of units, numerical value equations have the same form, including numerical factors, as the corresponding quantity equations.
NOTE 3 – An example of coherent system of units is the set of coherent SI units with the relations between them.

système cohérent d'unités, m
système d'unités, fondé sur un système de grandeurs donné, dans lequel l'unité de mesure de chaque grandeur dérivée est une unité dérivée cohérente
NOTE 1 – Un système d'unités ne peut être cohérent que par rapport à un système de grandeurs et aux unités de base adoptées.
NOTE 2 – Pour un système cohérent d'unités, les équations aux valeurs numériques ont la même forme, y compris les facteurs numériques, que les équations aux grandeurs correspondantes.
NOTE 3 – Un exemple de système cohérent d’unités est l’ensemble des unités SI cohérentes muni des relations entre elles.

3 время дифференцирования

время предварения
время дифференцирования
Время, в течение которого входной сигнал, изменяющийся с постоянной скоростью, достигнет значения выходного сигнала, изменяющегося с той же скоростью, в момент начала отсчета.

derivative action time
for a derivative element the same as the derivative action coefficient, if its input and output variables have the same unit
Note 1 – Then the derivative action time is given by TD = KD, where KD is the derivative action coefficient.
Note 2 – The derivative action time can also be given as the duration of the time interval that a rampwise variation of the input variable needs to reach the same value as the stepwise varying output variable.
[IEV ref 351-28-26]FR
constante de temps de dérivation
pour un élément à action par dérivation, la constante de temps de dérivation est égale au coefficient d'action par dérivation, si ses variables d'entrée et de sortie sont dans la même unité
Note 1 – La constante de temps de dérivation est alors donnée par TD = KD, où KD est le coefficient d'action par dérivation.
Note 2 – La constante de temps de dérivation peut également être donnée comme la durée de l'intervalle de temps nécessaire pour qu'une variation en rampe de la variable d'entrée atteigne la même valeur que la variable de sortie correspondante.

время интегрирования
Время, в течение которого интегральная составляющая регулятора изменяет выходной сигнал на значение, равное значению скачкообразного изменения входного сигнала.

integral action time
for an integral element, the reciprocal of the integral action coefficient, if its input and output variables have the same unit
Note 1 – The integral action time then is given by
TI=1/KI
where KI is the integral action coefficient.
Note 2 – The integral action time can also be given as that duration of the time interval which the output variable needs to reach the same value as a stepwise variation of the input variable.

constante de temps d'intégration
pour un élément à action par intégration, inverse du coefficient d'action par intégration, si ses variables d'entrée et de sortie sont dans la même unité
Note 1 – La constante de temps d'intégration est alors donnée par
TI=1/KI
où KI est le coefficient d'action par intégration.
Note 2 – La constante de temps d'intégration peut également être donnée comme la durée de l'intervalle de temps nécessaire pour que la variable de sortie atteigne la même valeur qu'une variation en échelon de la variable d'entrée.
