When the process was done, the porosity-a measure of the empty space in the structure-was about 94 percent, just below the theoretical limit of 96 percent.

当整个过程完成后，空隙度达到94%，刚好低于96%的极限水平。

This contradicts numerous theoretical studies which indicated a primarily tetrahedral coordination structure with a solvation number near 2 or 3, depending on the prevalence of ion pairing.

这与大量的理论研究——一个主要的四面体配位结构是2或3左右，取决于离子对的流动率的溶剂化数是相悖的。
