Putting lime into the oceans has the potential to decrease ocean acidity and reduce atmospheric CO2 levels.
向海洋中施石灰能够降低海水的酸性,并减少大气中的二氧化碳水平。
Additionally, the effect and criterion of lime treated expansive soils can be decided from swell potential and strength.
另外石灰改良膨胀土灰剂量确定和检验标准应该从膨胀潜势和强度两个方面确定。
Furthermore, addition of fibre caused a decrease in swelling potential of lime treated soils while led to an increase in shrinkage potential.
此外,在胀缩性方面,纤维的掺入减小了石灰土的膨胀性,但增加了收缩性。
