摘要
当高能激光穿过大气时,大气中的分子和气溶胶粒子吸热会使大气密度发生变化,从而导致局部折射率变化,由此产生热晕效应。本文主要分析了气溶胶粒子所致稳态热晕和含时热晕中的大气密度变化问题。
when a high energy laser(HEL)beam propagates through the atmosphere,a small portion of the energy is absorbed by certain molecules and aerosols.The absorbed energy heats the air and leads to the change of local refractive index which cause the effective of thermal blooming at last.This paper main studies the atmospheric density change in the thermal blooming due to aerosols.
