一氧化氮和酸性物质在大鼠吸入性肺损伤中的差异

After adding the acidic material,the pH reduced to neutral-m.

结果表明,花卉培养土的pH值由于配置比例不同而呈现从微碱性到强酸性的变化,保定植物园拟栽培花卉土壤的pH值为微碱性,加入酸性物质后土壤的pH值降低至中性-微酸性,适合多种花卉栽植。

The effects of acid materials, including furfural residue, solid oxalic acid, ferrous sulfate, sulphur powder and vinegar residue,on phosphate activation in calcareous soil were studied based on culture experiments.

结果表明,除醋渣外,其他几种酸性物质均可显著提高石灰性土壤磷的有效性,其效应从高到低依次为糠醛渣、固体草酸、硫酸亚铁、硫磺粉,速效磷的平均值依次较对照提高了26。

In this thesis , the effects of acid materials on calcareous soil were studied by using laboratory soil trial and pot experiments trail.

本文采用室内模拟试验和盆栽试验相结合的方法，研究了不同酸性物质对石灰性土壤的酸化效果；磷酸和硫酸对石灰性土壤pH值及微量元素有效性的影响；植物体内磷、有效铁、锌的关系；不同酸性基质对嗜酸植物生长的影响。
