As is well known that Low-molecular-weight organic acids ( LOAs) can promote activation of P and base ion from soil, and accelerate dissolution of soil minerals. 低分子量有机酸(Low-molecular-weightorganicacids,简称LOAs)能促进土壤中磷素及盐基离子的活化,加速土壤矿物溶解,早已被人们认识。
Based on the characteristics of existing structures, the analyses are presented for an effect on the resistance of existing structures using a deterministic load and random loas. 基于服役结构的特点,分析了确定性和随机性验证荷载对服役结构抗力的影响。
Therefore, from the angles of dissolution model, dissolution mechanism and influence factor, the article gives a introduction about the effect of LOAs on mineral dissolution. 因此,从溶解模型、溶解机理及影响因素等方面,概述了LOAs对土壤矿物的溶解作用。
Kinetics experiments indicate that LOAs accelerate K release from the soils obviously, and K release will show an accumulate tendency with the time. 动力学试验研究结果表明,有机酸能够明显的促进两种土壤钾的释放,并且释钾量随着时间的增加而呈现累积趋势。
