The Mg-O bonds, the Raman frequencies and the number of the v〓-SO〓 band of the ion pair chain〓(n=1-4) increase with the growing of the chain, and it is well consistent with the experiments. It explains that the phenomena of gel appearance in the supersaturate solution of MgSO〓 and the blue shift of Raman spectra, as well as the phenomena of FWHH getting wider.

在〓（n=1-4）离子对链中电荷交替分布，Mg-O键长随链增长而增长，拉曼光谱频率随链增长而增高，最大强度振动波段的数目随链增长而增大，这些计算结果解释了MgSO〓过饱和溶液中出现的凝胶现象和其拉曼光谱的波段蓝移和半峰宽变宽的变化。

The results show that the reflectivity in the low frequencies could be improved greatly when the FSS with suitable surface percentage of patch is used.

通常对电磁吸波材料的要求是高吸收能力和小的体积，而上述要求在吸波材料的设计中往往是相矛盾的。
