偏差模型 meaning in English

deviation model

An atmosphere structure constant cn2 model , which varies with height , is presented based on itu - r amplitude scintillation model , existing itu - r optical cn2 model and meteorologic measurement relative humidity and temperature profile data , at 10 ~ 30ghz . the log - amplitude scintillation deviation calculated in terms of the cn2 model based on humidity and temperature vertical profile compare with values predicted by means of itu - r and ortgies model . it is emerged that the calculation results based on the cn2 model agree almost with prediction results by itu - r and ortgies model at 10 ~ 30ghz and there is an advantage that relative humidity and temperature varied with height has be considered in the cn2 model
根据光波段的itu - rc _ n ~ 2模型， itu - r幅度闪烁标准偏差模型，和温度和相对湿度随高度变化的气象数据，在10 30ghz ，分析得到了大气结构常数c _ n ~ 2随高度变化的模型；并根据温度和湿度垂直分布数据计算了对数幅度闪烁_ x ，还与itu - r和ortgies模型的预测结果进行了比较，结果表明，在10 30ghz ，用该c _ n ~ 2模型计算的结果和用itu - r及ortgies模型预测的值符合较好，且在用c _ n ~ 2模型计算时考虑了温度和相对湿度随高度变化关系。
