本文还对超高频波段在一些特定区产生的散射增强，用电离层中某些尺寸的不均匀结构的影响给予初步解释。
This enhancement of scattered em waves under special condition of higher frequencies of special zones may be explained by using the influence of the irregular structure of some size in the ionosphere.
所以结构会处于一个复杂的不均匀温度场之中。
Therefore, the structure will be in a complex of non-uniform temperature field.
当不均匀沉降较明显时，必须检查其对结构内的作用效应。
Where significant differential settlements are likely their influence on the action effects in the structure should be checked.
