attenuation rate meaning in Chinese
衰减率
Examples
- And , the attenuation rate rose out of fog is studied , calculating that and modeling it prediction formula using non - linear system identification method
计算了雾的衰减率，并用非线性系统辨识方法得到了雾的衰减率的预报模型；计算了雾的反射率随能见度的变化规律。 - The deviation value was used to characterize the inhomogeneous degree of concentration fields , and the attenuation rate with time was used to characterize the injection dispersion performance of flow field
以此方差近似表征了示踪剂浓度场的非均匀度，其衰减规律可用于定量描述振荡流场的注入分散特性。 - Traces of dyes indicate that the stable length increases with an augment of h , and the relations between spatial attenuation rates of disturbance and wavenumbers are correspondent with theoretical results by the analysis of spatial mode
染色线观测显示h值增大使扰动失稳距离增加，扰动衰减率与波数的关系同空间模式稳定性分析的理论结果定性一致。 - As for a space - based cloud radar , the change of the radar reflectivity n and the change of attenuation rate along with the cloud liquid water content have been compared between 37 ghz and 94ghz . the transmittance t of single level cloud for different heights and liquid water content has also been calculated at 2 frequencies . by defining a = n tr , which combines both effects of radar reflectivity and transmittance , we have examined the values of a at 37ghz and 94ghz for high , middle and low cloud liquid water contents
对空间测云雷达，讨论了37ghz和94ghz这两个频率的雷达反射率和衰减系数随云液水含量的变化；计算了不同高度的单层云在不同频率，不同含水量情况下的云层透过率_ ；定义a = _来综合考虑雷达反射率和透过率对空间测云雷达回波的影响，分析比较了云含水量高、中、低时37ghz和94ghz的a值大小。
