English term or phrase:derating
Definition from Martek Power Abbott, Inc.: Reducing one operating parameter to compensate for changes in other parameters to maintain reliability. For example, the reduction in output power at elevated temperatures.
Two things can be inferred from these ratings: the maximum storage temperature is equal to the derated temperature. Also, the slope of the derating can be used to calculate an equivalent thermal resistance in degrees C per watt. The difference between the no-load and maximum full load temperature is less than or equal to the temperature rise at full load. P-N Designs, Inc.
Most dc/c manufacturers have design-derating guidelines, but sometimes designers use guidelines they have developed themselves. As engineers, we derate components to improve their reliability by decreasing component stress. Hearst Business Communications, Inc
A derating chart is often used, with derating starting at 70oC. Since parameters are application dependent, power de-rating curves or charts should be considered general rather than absolute, and only used as a guideline. interfacebus.com
Definition: Ev aletlerinin kapasitelerinin düşürülmesi bir taraftan dünya çapındaki enerji gereksinimini azaltırken, diğer taraftan sera gazı salınımının düşürülmesi suretiyle de gelecek nesillere daha yaşanabilir bir çevreninin islah edilmesine önemli ölçüde sürekli katkı yapılması sağlanmış olur.
Definition from own experience or research: Ev aletlerinin kapasitelerinin düşürülmesi bir taraftan dünya çapındaki enerji gereksinimini azaltırken, diğer taraftan sera gazı salınımının düşürülmesi suretiyle de gelecek nesillere daha yaşanabilir bir çevreninin islah edilmesine önemli ölçüde sürekli katkı yapılması sağlanmış olur.
Derating can be defined as "the practice of limiting electrical, thermal and mechanical stress on parts, in a given design application, to levels that are below their specified ratings or their proven capabilities in order to enhance reliability". Reducing these stresses extends part life and usually, but not always (depending upon the nature of the part and the specific parameter involved) improves part reliability and hence system reliability. In addition, derating helps protect parts from unforeseen application anomalies and overstresses.
Derating is a structured engineering approach to part application tailored to deal with, among other things, part variability. All parts do not have the same "strength." Part "strength" variability within any given population of parts is a fact of life and derating helps to compensate for this variability. Even parts from a so-called homogenous population, the same production line and from the same "production lot" exhibit some parameter variability. When so-called "interchangeable parts" are supplied by different manufacturers, possibly using different internal circuitry and different manufacturing processes, this parameter variability can be expected to become even greater. Derating helps to compensate for this type of "strength" variability. - İnternet

Notes to answerer
Binnur Tuncel van Pomeren Tabi, kesinlikle! Sadece biraz tercihi bir durum. Kesinlikle yanlis oldugunu dusunmuyorum soyledigim gibi!
Belli ki hep guc, kapasite soz konusu oldugunda kullaniliyor. Ama grafikte adindan bahsetmeye gerek duymamislar (yani power derating dememisler) Ben de o yuzden derating curve icin dusurme egrisi diyenlere de katilacagimi ifade ettim sadece. Iyi gunler!
