根据热力学平衡原理和设计的可逆电池反应，由 E~0Hg~(2++S/HgS数据，计算了 E~0HgCl_4~(2++S/HgS+4Cl~-数值，将其与 HNO_3的标准电极电位比较，定量地揭示了 HgS 溶于王水的原因在于该溶液中高浓度 Cl~-离子降低了 HgS 中硫的还原电位，从而提高了 HgS 的还原性所致，并非王水的氧化性比 HNO_3的更强。

Thermogravimetry curve shows that NiOH embedded in AAO decomposed slowly compared to thin film.

可能存在两个原因：氧化钛纳米丝具有比氧化钛纳米膜更大的比表面积；氧化钛纳米丝的光学带隙大于氧化钛纳米膜的，带宽的增加，使得价带电子电位变得更正，导带电位变得更负，这实际上增加了光生电子和空穴的氧化还原能力，提高了半导体光催化氧化有机物的活性。
