原形：blackbody复数：blackbodies

A blackbody is an idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence.
黑体是一个理想的物理物体，它能吸收所有照射到其上的电磁辐射，无论频率或入射角度如何。
The temperature of a blackbody can be determined by its spectral radiance, according to Planck's law.
根据普朗克定律，可以通过黑体的光谱辐亮度来确定其温度。
The sun can be approximated as a blackbody radiator at around 5,500 degrees Celsius.
太阳可以近似看作在大约5500摄氏度时的一个黑体辐射器。
Blackbodies emit thermal radiation due to their temperature and have a continuous spectrum.
黑体由于其温度而发出热辐射，并且具有连续的光谱。
In astronomy, stars are often modeled as blackbodies for the purpose of analysis.
在天文学中，为了分析目的，恒星经常被建模为黑体。
A perfect blackbody has an emissivity of 1, meaning it emits the maximum possible amount of radiation for its given temperature.
完美的黑体具有发射率1，意味着对于给定的温度，它发出的最大可能辐射量。
The Stefan-Boltzmann law states that the total energy radiated by a blackbody is proportional to its surface area and the fourth power of its absolute temperature.
斯蒂芬-玻尔兹曼定律指出，黑体所辐射出的总能量与其表面积及其绝对温度的四次方成比例。
The color of light emitted by a blackbody changes with increasing temperature, from red to orange, yellow, white, and finally blue-white as the temperature rises.
随着温度升高，黑体发出的光线颜色会从红色变为橙色、黄色、白色，最后变为蓝白色。
Engineers use blackbody calibration sources to calibrate infrared cameras and other thermal sensors.
