The study of the radiation emitted by atoms was largely responsible for the growth of modern ideas about atomic structure . 对原子发出的辐射的研究在很大程度上导致现代的原子结构概念的发展。
The resolution of a telescope is determined by the ratio of the wavelength of the radiation received to the diameter of the instrument . 一个望远镜的分辨本领取决于它所接收的辐射的波长对这个仪器本身的直径的比值。
With a careful theoretical analysis various physical parameters such as the gas density, temperature, and pressure, and the ultraviolet and ionizing radiation fluxes can be derived . 通过仔细的理论分析，可以推导出如气体密度、温度和压力等各种物理参量，以及紫外辐射和电离辐射的流量。
The absorption of this radiation in various lines followed by cascade transitions to lower levels might ultimately produce an anomalously high population for the excited levels of these molecules . 在各谱线处对这种辐射的吸收以及接着向低能级的级联跃迁最终可能使这些分子的激发能级产生异常高的粒子数。
