1·Scientists have known for a long time that aerosols such as soot, dust and other small particulate matter, alter cloud density and the radiative balance of the atmosphere.
科学家们很早之前就发现，诸如煤烟、灰尘和其他细小的微粒，能改变云体的密度及大气的辐射平衡。
2·This is the study of "radiative transfer, " an elegant and difficult branch of theory.
这就是“辐射传输”，一门非常高深艰难的学科。
3·The new study focused on surface melt, runoff and the number of days when bare ice, free of snow, is exposed to the Sun's radiative force.
这项新研究的重点是表面融化，径流以及暴露于太阳辐射下的裸冰和无雪天数。
4·In this approximation, it is assumed that the effect of radiative heat transfer would be so strong that the temperature of the medium could be regarded as uniform.
在这种近似中，突出地强调了辐射热传导的作用，即认为介质中的温度分布由于热传导极强而可以近似地看成与空间无关。
5·The impacts of clouds on the radiative heating rate depend on the height and thickness of clouds.
云对沙尘层辐射加热(冷却)率的影响与云的高度和厚度有关。
