查询词典 deoxidant

But it is difficult to find a perfect method to control drum boiler's corrosion. Now deoxidization water chemistry for drum boiler has the characteristics of high corrosion speed, high Fe content in feedwater and boiler water, high scaling speed, short chemical cleaning interval and needing poisonous chemical deoxidant, etc.

火力发电站由于大量使用金属材料，并且金属材料的使用环境大都接近其极限使用条件，因而常由腐蚀而引发事故，造成重大损失。

Among the various packaging conditions examined, black soybean or black soybean koji held with desiccant and deoxidant showed the highest retention of total phenolic compound, isoflavone and antioxidant activity.

在所测试之包装条件中，以含乾燥剂及脱氧剂之处理组保有最高量之总酚、异黄酮素与抗氧化活性，不添加任何食品保存剂处理组之含量与活性最低。

The four conditions are as follows: the molten alloy only with the addition of deoxidant during melting; only applying high-density pulse electric current on castings during solidification; compound addition of grain refiner and sodium modifier, and addition of borax r modifier liquid along with applying pulse electric current during melting.

这4种工艺条件分别为：在合金液熔炼过程中，除了加脱氧剂外不做任何处理；凝固过程中单独施加高密度电脉冲；添加晶粒细化剂和钠盐变质剂混合剂，或者添加硼砂变质细化剂，并施加高密度电脉冲。

The vacuum package and adding deoxidant model 100 package with material of low venting quality can constrain the accelerating speed of peroxide values,TBA values and carbonyl group values,and delay rancidification obviously.

结果表明：采用低透气性的包装材料添加100型铁系脱氧剂抽真空包装，可明显抑制过氧化值、TBA值和羰基价的增加，延缓酸败。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
