température négative
31negative temperature coefficient thermistor — (NTC) Electronic thermistor which decreases in resistance as temperature increases …
32Deborah Chung's "apparent negative resistance" — History In July 1998, Deborah Chung and Shoukai Wang of the University of Buffalo presented the results of an experiment that showed an apparent absolute negative resistance in bare carbon fibers held together by pressure.[1] In the experiment,… …
33absolute temperature — Temperature measured with respect to absolute zero, i.e., the zero of the kelvin thermodynamic scale of temperature, a scale which cannot take negative values …
34Neutron temperature — A chart displaying the speed probability density functions of the speeds of a few noble gases at a temperature of 298.15 K (25 C). An explanation of the y axis label appears on the image page (click to see). Similar speed distributions are… …
35Thermodynamic temperature — is the absolute measure of temperature and is one of the principal parameters of thermodynamics. Thermodynamic temperature is an “absolute” scale because it is the measure of the fundamental property underlying temperature: its null or zero point …
36Potential temperature — The potential temperature of a parcel of fluid at pressure P is the temperature that the parcel would acquire if adiabatically brought to a standard reference pressure P {0}, usually 1000 millibars. The potential temperature is denoted heta and,… …
37Gram-negative bacteria — Microscopic image of Gram negative Pseudomonas aeruginosa bacteria (pink red rods). Gram negative bacteria are bacteria that do not retain crystal violet dye in the Gram staining protocol.[1] In a Gram …
38Digital Negative — For the informal use of digital negative , see Raw image format. Digital Negative (DNG) Filename extension .dng Developed by Adobe Systems Initial release …
39Minimum resolvable temperature difference — (MRTD) is a measure for assessing the performance of infrared cameras, and is inversely proportional to the modulation transfer function. Typically, an operator is asked to assess the minimum temperature difference at which a 4 bar target can be… …
40Inversion temperature — The inversion temperature in thermodynamics and cryogenics is the critical temperature below which a non ideal gas (all gases in reality) that is expanded at constant enthalpy will experience a temperature decrease, and above which will… …
