中文百科

热辐射

热辐射,是一种物体用电磁辐射的形式把热能向外散发的热传方式。它不依赖任何外界条件而进行。它是热的三种主要传递方式之一。

辐射物的功率 P_{rad} = \epsilon \sigma AT^{4}

斯特藩-玻尔兹曼常数 \sigma = 5.6704 \times 10^{-8} W  \cdot m^{-2} \cdot k^{-4}

物体表面放射率 \epsilon 介于0~1之间,黑体辐射为1

Thermal radiation 热辐射

The peak wavelength and total radiated amount vary with temperature according to Wien's displacement law. Although this shows relatively high temperatures, the same relationships hold true for any temperature down to absolute zero. Visible light is between 380 and 750 nm.
Thermal radiation in visible light can be seen on this hot metalwork. Its emission in the infrared is invisible to the human eye and the camera the image was taken with, but an infrared camera could show it (See Thermography).

Thermal radiation is electromagnetic radiation generated by the thermal motion of charged particles in matter. All matter with a temperature greater than absolute zero emits thermal radiation. When the temperature of the body is greater than absolute zero, inter-atomic collisions cause the kinetic energy of the atoms or molecules to change. This results in charge-acceleration and/or dipole oscillation which produces electromagnetic radiation, and the wide spectrum of radiation reflects the wide spectrum of energies and accelerations that occur even at a single temperature.
