replacement reaction

基本解释

The experimental data showed that high temperature was beneficial to improve replacement reaction rate.
实验表明，提高温度有利于置换反应的进行。
And is was found the degree of replacement reaction increased with the advance of time and temperature in raction.
在合成时，反应温度越高，反应时间越长，亲核取代反应越完全。
When accessing to the by-product, the speed of replacement reaction is choked back and soil exchangeable sodium can not immediately discharged soil.
当加入脱硫副产物后，置换反应的速度受到抑制，土壤中的代换性钠也不能立即排出土体。
