The effect of vitriol excesscoefficient, reaction temperature and reaction time on the leaching ratio has been studied.
其次是硫酸浸取，研究了硫酸过量系数、酸浸温度和酸浸时间对铁的浸出率的影响。

And with the excesscoefficient of 1. 2, the workability and mechanical properties of mortar were significantly improved.
采用1.2的超量系数，砂浆的和易性能和力学性能有显著提高。

In the real bake-out process, it suggests that the air excesscoefficient of burning should be controlled within 1 in order to avoid electrode being oxidized by high temperature fume;
