The hydroquinone as radical scavenger could inhibit it by removing radical produced in the reaction process.
结果表明,自由基链反应引发剂铜离子能够加速亚硫酸盐与氧的反应,自由基链反应终止剂对苯二酚能够通过消除亚硫酸盐氧化过程中生成的自由基而抑制反应,水的pH值、碱度和硬度成分则无影响。
The first kind is radical scavenger, inhibiting reaction by removing radical produced in the reaction process.
结果发现,下列三类物质能够阻滞亚硫酸盐与氧的反应:第一类物质是自由基链反应终止剂,通过消除亚硫酸盐氧化过程中生成的自由基而抑制反应;第二类物质是螯合剂,通过螯合亚硫酸盐溶液中的过渡族金属元素催化剂杂质而减缓反应速度;第三类物质是链反应引发剂,由于添加过量而由引发剂转变为终止剂,试验结果为亚硫酸盐氧化的自由基机理提供了有力的证据,也为防止亚硫酸盐的贮存失效提供了多种有效的方
Experiment shows that the high-accurate mineral processing modeling can be achieved if the method of early stopping is adopted to set up the model to overcome the shortcoming.
在应用BP神经网络建模时,有时会因盲目地过多的训练网络而造成网络“过度拟合”,为了克服这一缺点,经专门实验证明:采用“早终止”的方式建模,可以建立高精度的选矿数学模型。
To overcome the "overfitting" of a BP model applied to modeling the practical prediction induced by over-training the BP model, the paper discussed the method of " early stopping" during training a BP model for prediction.
为克服基于BP网络的实用预测建模中,盲目地过多训练网络所造成的网络“过度拟合”问题,本文论述了采用“早终止”方式的基于BP网络的预测建模方法,并以一选矿建模实例来说明这种方法的应用及“早终止”方式的具体实施途径。
