coarse silt

The marked difference in various soil are that there are many fine silt and clay but rather less for coarse silt and sany in strong accumulation clay layer, the loamy layer are just the contrary.

各土壤间粉粒含量差异很小，所不同的是，坝地富粘层粗粉粒少细粉粒多，砂粒少粘粒多，坝、坡轻壤层反之。

本文以植物为研究材料,测定了它们对滑刃目松材线虫、垫刃目南方根结线虫、水稻潜根线虫离体活性和毒力,并对活性较高的植物粗粉进行了室外盆栽防效试验。

By means of the tests of compressive strength, toxicity characteristic leaching procedure(TCLP) and dynamic leaching test(DLT), it was studied that the feasibility of solidification and stabilization (S/S) of heavy metals using reject fly ash (rFA).

利用强度发展、毒性浸出试验(TCLP)和动态浸出试验(DLT)等手段探讨了废弃粗粉煤灰水泥系统固化/稳定含铅、铜和锌的重金属废弃物的可能性。

Compared with the influence of different chemical activators on the strength development, hydration degree of reject fly ash and hydration products, it can be found that the addition of Na 2SO 4 and K 2SO 4 can significantly increase the compressive strength at both early and later curing ages.

通过研究不同化学激发剂对废弃粗粉煤灰 -水泥系统的强度发展、水化程度、水化产物等的影响 ,发现掺入Na2 SO4 和 K2 SO4 可以大幅提高废弃粗粉煤灰 -水泥系统在早期和晚期的抗压强度 ,而掺入 Ca Cl2 和 Ca(OH) 2 的效果则不明显 ,X射线衍射的测试结果也证明了这一点。

Comparing the influence of chemical reagents-Na 2SO 4 and K 2SO 4 on the strength development,hydration degree and porosity of reject fly ash blended cement pastes,it is found that the addition of these two chemical reagents can increase the compressive strength significantly at both early and later curing stages.

通过研究碱式硫酸盐对废弃粗粉煤灰 -水泥系统的强度发展、水化程度及样品孔隙率等的影响 ,发现掺入Na2 SO4 和 K2 SO4 可以大幅提高废弃粗粉煤灰 -水泥系统在早期和晚期的抗压强度 ,在试验条件下 ,掺 Na2 SO4 的最佳掺量为总重量的 6 % ,K2 SO4 的最佳掺量为总重量的 4 % ,这些最优掺量都与激发剂的溶解度有关。
