根据分析所得到的各种衰减量，可以推导出工作于此波段的近程雷达受作用距离的影响及抗干扰性能。

Based on the all attenuation, we can find the short range radar worked in this band is affected by action distance and interfere.

由于化学转换和衰减的作用，初生污染物随着下风距离而较快地减少，特别是在10公里以后的中距离上更加明显；

As a result of chemical conversion and decay, the primary pollutant decreases with the downwind distance more rapidly, especially as the mesoscale distance further than 10 km.

知识生产的局部溢出是存在的； 邻近地区的R&D的努力对当地知识生产的影响作用是随着距离而衰减的。

Moreover, the production of knowledge by regions seems to be also affected by spatial spillovers due to R&D activity performed in other regions.
