Quantitative model considering surface enrichment to estimate soil erosion rates using 137cs 地表富集作用的土壤侵蚀速率的定量模型
Cells , and the cyanobacterial physiological process is involved in lanthanum bioaccumulation 满江红鱼腥藻对镧的富集作用可能与其光合作用电子传递和能量合成有关。
Experiments of the influence of rare earth element lanthanum on the growth , chlorophyll a and oxygen production of cyanobacterium 的生理影响和满江红鱼腥藻对镧的富集作用进行了研究。
The high sensitivity and good selectivity were accomplished in the determination of the dopamine due to the selective penetration and the accumulative effect of the . polyglycine membrane 利用聚甘氨酸膜的选择渗透性和富集作用,研制了高灵敏度和高选择性的多巴胺生物传感器。
Its mechanism is to reduce the surface tension of solution , to enhance the efficiency of nebulization , to generate glue group of chemical combination and to concentrate molybdenum by surfactant 其机理是溶液表面张力的降低、雾化效率的提高、胶团化合物的形成及表面活性剂对钼的富集作用。
However , more soil pollutions have no clear signs , but the production is decreased . especially , the toxins can remain in the agricultural products and poison the people or livestock who ingest them 更多的土壤污染并无明显表现,却降低了农产品的质量,特别是通过农作物对有害物的富集作用,暗地里危害牲畜和人体健康,必须引起高度警惕。
This paper reviews the formation and feature of iron and manganese plaque , alleviation of metal ( loid ) toxicity via adsorption and accumulation , eutrophication purification , plant acid proof and barren resistance 文章综述了植物根表铁锰氧化物的形成与特征,对有害金属和类金属污染物、有机污染物的吸附和富集作用,对富营养化水体的净化作用,以及提高植物的耐酸和耐贫瘠能力。
However , more soil pollutions have no clear signs , but the production is decreased . especially , the toxins can remain in the agricultural products and poison the people or livestock who ingest them . extreme measures must be taken to prevent this from happening 更多的土壤污染并无明显表现,却降低了农产品的质量,特别是通过农作物对有害物的富集作用,暗地里危害牲畜和人体健康,必须引起高度警惕。
