置换作用 meaning in English
metathesis
Examples
- But how they interact with other substances , such as gold , acts as a proxy for that behaviour
但是他们如何与其他物质交互作用,比如金,起着置换作用。 - Our aim is to provide reference data for the mechanism of the effects of ree on crops and the safety evaluation of re used in agriculture . 1 . in soil culture experiment , re applications with appropriate dose in dry condition increased the contents of soil available n , whose no - effect value were 505mg / kg at eighth week , whereas higher levels of re had negative effects , re applications with both appropriate and higher dose in inundated condition reduced the contents of soil nh / - n and hydrolysable n . re treatment concentrations showed significant positive correlation with the contents of soil exchangeable re . and significant negative correlation with the contents of soil available p and soil ph value . there was no significant effects of re on soil exchangeable cations , but applications of re increased the contents of soil water soluble cations , especially that of ca2 * and mg2 +
两种培养条件下,稀土处理浓度与土壤交换态稀土含量成正比,与有效磷含量、土壤ph成反比,对土壤交换态盐基离子含量无显著影响,但通过置换作用增加了水溶态离子,尤其是ca ~ ( 2 + ) 、 mg ~ ( 2 + )离子的含量;第二周稀土处理增加交换态zn含量,对交换态fe有降低作用,旱培条件下增加交换态mn含量,淹水条件下对其有降低作用;第八周稀土处理均提高交换态fe 、 mn 、 zn含量,其机制主要与稀土降低土壤ph有关。
