16.We should consider that multiple addition or increase concentration of Krilium in field practice may strength the effectiveness of soil amelioration.
同时,野外进行改良应该考虑多次少量施用或增加改良剂浓度的方法来增强改良效果。
17.Aluminum toxity is the main factor that limits crops growth in the acid soil, and many crops response to micromole aluminium.
铝毒是酸性土壤限制物生长的主要原因之一,许多物对微摩尔浓度的铝发生毒害反应。
18.The membrane can be used for concentrating ethanol from dilute ethanol-water mixture through pervaporation process owing to its alcohol-permselective properties.
通过对低浓度乙醇-水的渗透蒸发的试验研究,表明该膜是一种性较好的新型优先透醇膜。
19.Otherwise it will be very difficult to redissolve the crystallized out component, since these solutions contain already a high content of solutes.
否则一旦析出,由于溶液含有高浓度的盐类,就很难重新溶解。
