As gas in the seams effuses all around on the horizontal direction and can not straightly goes upwards, the entrainment is less, and the mash processing efficiency is high; 由于气体在缝隙中以水平主向向四周喷出,气体不会向上直冲,因此雾沫夹带少,处理醪液效率高;
Restoration of lead and zinc mine tailings in South China Effect of Different Amendments on the Growth and Heavy Metals Accumulation of Juncus effuses Grown on the Soil polluted by Lead/ Zinc Mine Tailings 华南铅锌尾矿生态恢复的理论与实践不同改良剂对铅锌尾矿污染土壤中灯心草生长及重金属积累特性的影响
With the decrement by 10% in biomass of Juncus effuses as a reference point, the threshold for soil Cd, Pb and Cu was set at 10,100 and 100~ 200 mg · kg~ (-1), respectively. 以灯心草生物量减产10%为依据,将土壤中Cd、Pb、Cu3种重金属临界值分别设定为10、100、100~200mg.kg-1。
Effects of Cu, Cd, Pb, Zn and As single pollution on the growth and heavy metal accumlation character of juncus effuses 重金属单&污染对灯心草生长及重金属积累特性的影响
The Eco-toxicological Effect of Cu, Cd, Pb, Zn and As Compound Pollution on Juncus Effuses and Its Accumulation Character of Heavy Metals 重金属复合污染对灯心草的生态毒性效应及重金属积累特性的影响
Physical properties of lava, flow rate of magma as it effuses from the underground and its surrounding environmental factors, play the important roles in learning the transportation and cooling of lava flow and dynamical mechanics. 熔浆的物理性质、岩浆从地下流出的速率及影响其变化的环境因素是研究熔岩流的运移和冷却及其动力学机制的重要方面。
The soil criteria value of As in soil remains to study further, it was vary in Cd, Pb, Zn, Cu and As uptake and distribution in Juncus Effuses. 灯心草不适合在Zn污染的土壤中种植,土壤中As临界值则尚需作进一步的研究来确定。
