【摘要】 引入了大气中的吸收系数、风速、大气压强、密度和温度模型,然后利用加权等效的方法对上述参数进行了等效处理,得到了等效热畸变参数,从而把斜程传输下的热晕问题转化为水平传输下的热晕问题,利用该模型进行了理论计算。结果表明,天顶角越大,等效热畸变参数越大,热晕效应越强。计算结果符合理论预期的结果。更多还原

【Abstract】 The model of absorbtion coefficient,wind speed,pressure and temperature of atmosphere were introduced,the weighted equivalent method was adopted to deal with the above mentioned parameters,so that the thermal blooming effect on slant path transmission was transferd to horizon transfer problem.With this equivalent model,theoretical calculations are carried out,the results show that the larger that of zenith angle,the greater that of equivalent thermal distortion parameter,which lead to stronger thermal blooming effect.In accordance with the theoretical results it is expected.更多还原
