The results showed that the amounts of base cations leached from calcareous soils and coastal solonchak were lower than the cation exchange capacity and the releasing amounts of Al3+ being lower than 0.40mmol·kg-1 all the way under the treatment of simulated acid rain with each pH value from 2.5 to 5.6,so the H+ buffering...
结果表明,石灰土和滨海盐土的阳离子淋溶量低于阳离子交换量,土壤主要处于阳离子交换缓冲范围和碳酸盐-硅酸盐缓冲范围,Al释放量一般低于0.40mmol·kg~(-1),铁铝土纲系列土壤在阳离子释放总量超过阳离子交换量后,淋溶液pH值急剧下降,此时Al淋溶量明显增加,质子缓冲转向Al缓冲范围,其释放量决定于土壤富铁铝化程度的高低和活性Al含量的多少,紫色土在低pH模拟酸雨淋溶下,由于含大量硅铝率较高的易风化原生或次生矿物,盐基释放量高于CEC,但Al释放量未明显增加,淋溶液pH也较稳定,土壤尚处于矿物风化为主的硅酸盐缓冲范围。

In this dissertation, the weak gels with good thermal stability and/or salt tolerance for use in EOR were prepared from HPAM and aluminium citrate or the compound containing hydroxymethyl groups in aqueous solution. The gelation mechanisms, structure, and properties of the HPAM-AlCA and HPAM-PRIM gels were investigated. For the HPAM-AlCA gelling system, the effects of aluminium : citrate and pH value on the properties of AlCA were systematically studied.
