The experimental data showed that high temperature was beneficial to improve replacementreaction rate.
实验表明，提高温度有利于置换反应的进行。

When accessing to the by-product, the speed of replacementreaction 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。

The preparation method of potassium pentaborate (KB5O8) was studied with the replacementreaction between potassium chloride and sodium pentaborate solution.
