Conductivity, английский
- Conductivité
- The rate at which heat is transmitted through a material.
- A term used in describing the capability of a material to carry an electrical charge. usually expressed as a percentage of copper conductivity copper being one hundred (100%) percent. conductivity is expressed for a standard configuration of conductor.
- Проводимость
- Удельная электропроводность; удельная электрическая проводимость
- Parameter used for characterising hydrogeological conditions, more
- This is the inverse of resistance, and refers to the ability of a conductor to carry current.
Conducting, английский
Conduction, английский
- Conduction
- The direct transfer of heat energy through a material.
- The transfer of energy through a solid without motion of the conducting solid as a whole. steady-state conduction calls if the temperature at each point is independent of time. unsteady or transient conduction situations changes with time (time dependant)
- The process of passing heat, sound or nervous impulses from one part of the body to another
- Проводимость; электрическая проводимость; электропроводность
- The transfer of heat energy through matter.
- The transfer of heat energy in materials (usually solids) via molecular scale vibrations and collision interactions.
- Heat transfer to another body or within a body by direct contact.
- Heat transfer occurring when more energetic particles collide with — and thus impart some of their heat energy to — adjacent less energetic (slower moving) particles. this action is passed on from one atom (or free electron) to the next in the direction of cooler regions. thus, heat always flows from a warmer to a cooler region.1 conductivity, thermal (k): material property defining the relative capability to carry heat by conduction in a static temperature gradient. conductivity varies slightly with temperature in solids and liquids and with temperature and pressure in gases. it is high for metals (copper has a k of 380 w·m–1·k–1) and low for gases and porous materials (concrete has a k of 1.0 w·m–1·k–1).3 682 infrared and thermal testing

Conductance, английский
- Of a tube, manifold, or leak path, flow characteristics expressed as a volumetric flow rate in m3/s. see also leakage rate; mass flow rate; rotameter; throughput. d
- (1) in leak testing, the flow characteristics of a tube, manifold or leak path expressed in m3·s–1. (2) transmission of electric current through material. conductance (g) is measured in siemens (s). inversely related to electrical resistance (r):
