1) indirect reduction index
间接还原指数
1.
Based on the research of direct and indirect reduction during self-reducing reaction of iron ore coal mixed briquettes at high temperature, an indirect reduction index α was defined, and the relation between indirect reduction index (α) and direct reduction degree (γd) of self-reducing reaction was established.
通过对内配煤团块高温自还原过程中的直接还原和间接还原反应的研究,定义了内配煤团块自还原反应的间接还原指数(α),并建立了间接还原指数(α)与直接还原度(γd)之间的关系。

间接指数
1.
In this paper,we classify investor sentiment index,which has been used in studies both domestic and abroad,into two categories: the first one is direct index,which is acquired directly by surveying investors,the other one is indirect index,which is calculated by relevant data that can reflect investors psychology.
对国内外学者在投资者情绪指数方面的研究工作进行了研究梳理,把它们划分为两类:一是通过直接调查投资者的情绪而得到直接指数;另一类是通过获取客观数据整理后,间接反映投资者的心理变化的间接指数。
6) indirect redox-titrimetry
间接氧化还原法
1.
The oxygen deficiency in the CexZr1-xO2-δ solid solution was determined by indirect redox-titrimetry after dissolving the solid sample in 3 mol/L sulphuric acid.
用3 mol/L硫酸溶液溶解样品,(NH4)2Fe(SO4)2作为还原剂,K2Cr2O7作为氧化剂,利用间接氧化还原法测定CexZr1-xO2-δ固溶体的氧缺陷值δ,方法的相对标准偏差为1。

indirect reduction
J ianjie huanyuan间接还原(indireet reduetion)用气体还原剂CO或H:将金属氧化物还原成金属的过程，属还原熔炼范畴。 金属氧化物MeO被CO还原成金属Me的反应为: MeO+CO一Me+COZ平衡气相成分与温度的关系为: △G。~A+BT一RTln%COZ/%CO=0式中△G“为标准自由能变化，A和B为与MeO有关常数，%COZ、%CO为平衡气相成分，T为反应热力学温度，R为气体常数。 对于某Meo的还原，只要控制一定的还原条件，即温度和气相中CO、CO:浓度，就可使CO还原MeO的反应顺利进行。对于H:还原MeO的间接反应，情况也类似。
