同时，其pH低，Eh高，这是因为周期性的干湿交替会促进矿物的表面风化，

At the same time, its pH is low and Eh is high. This is because the periodic dry and wet alternation will promote the weathering of the mineral surface and destroy the crystal lattice structure of the mineral (such as silicate minerals), which is beneficial to acidic media and strong oxidizing minerals. Release (Xuan, 2013; Sun, 2016).

At the same time, its pH is low and Eh high because periodic wet and dry alternatings promote surface weathering of minerals, destroy the lattic structure of minerals (e.g. silicate minerals), and facilitate the release of acidic media and more oxidizing minerals (Xuan, 2013; Sun, 2016).

At the same time, its pH is low and EH is high, which is because the periodic alternation of drying and wetting can promote the surface weathering of minerals, destroy the lattice structure of minerals (such as silicate minerals), which is conducive to the release of acidic media and highly oxidizing minerals (yuan, 2013; sun, 2016).<br>
