It should be noted that not only in the complex perovskite like BaO3,(X=Mg, Zn, Co, Ni, Mn: Y=Nb, Ta) but also in the compounds with tungsten bronze structure such as Ba6-3xLn8+2XTi18O54, they are consisted of corner-sharing oxygen octahedra and the ratios of ion in B site to ion in A site are usually larger than one.

值得注意的是业已开发出来的材料不论是复合钙钛矿BaO_3，(X=Mg，Zn，Co，Ni，Mn；Y=Nb，Ta)还是钨青铜结构，它们都是由氧八面体共顶连接，而且氧八面体内、外阳离子比例都等于或略大于1，因此，我们推测在B位与A位阳离子比例略小于1的类钙钛矿结构中极有可能存在具有优良介电性能的新材料。

However, because S is more easily combined with Fe than As does, hence when hydrothermal fluids are rich in S, the possibility of As presence in pyrite crystal lattice decreased, but the chance for Co and Ni to substitute Fe in pyrite crystal lattice increased, thus S rich is not favorable for the formation of P type of pyrite.

但另一方面，由于S与As相比更易与Fe结合，因而成矿介质中富S将使As进入黄铁矿晶格中的能力或几率降低，并进一步使Co、Ni因补偿类质同像进入黄铁矿晶格中代替Fe的能力或几率增大，反而不利于形成P型黄铁矿。
